    return;
(the body is just a function called for each item)

When you converted your loop into a compatible definition for the Parallel.Foreach logic, you ended up making the statement body a lambda. Well, that is an action that gets called by the Parallel function.

So, replace `continue` with `return`, and break with `Stop()` or `Break()` statements.

How to get first 5 characters from string

I have a `LinearLayout` (oriented horizontally) that contains 3 buttons. I want the 3 buttons to have a fixed width and be evenly distributed across the width of the `LinearLayout`.

I can manage this by setting the gravity of the `LinearLayout` to center and then adjusting the padding of the buttons, but this works for a fixed width and won&#39;t work for different devices or orientations.

```
&lt;LinearLayout
    android:layout_width=&quot;match_parent&quot;
    android:layout_height=&quot;wrap_content&quot;
    android:gravity=&quot;center&quot;
    android:orientation=&quot;horizontal&quot;&gt;

    &lt;Button
        android:id=&quot;@+id/btnOne&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:width=&quot;120dp&quot; /&gt;

    &lt;Button
        android:id=&quot;@+id/btnTwo&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:width=&quot;120dp&quot; /&gt;


    &lt;Button
        android:id=&quot;@+id/btnThree&quot;
        android:layout_width=&quot;wrap_content&quot;
        android:layout_height=&quot;wrap_content&quot;
        android:width=&quot;120dp&quot; /&gt;
&lt;/LinearLayout&gt;
```


Is it possible to evenly distribute buttons across the width of a LinearLayout

I am porting some code to `Parallel.ForEach` and got an error with a `continue` I have in the code. Is there something equivalent I can use in a `Parallel.ForEach` functionally equivalent to `continue` in a `foreach` loop?

    Parallel.ForEach(items, parallelOptions, item =&gt;
    {
        if (!isTrue)
    	    continue;
    });

I&#39;ve had been told that since .net linq is so slow we shouldn&#39;t use it and was wondering anyone else has come up with the same conclusion, and example is:

Took 1443ms to do 1000000000 compares non-LINQ.  
Took 4944ms to do 1000000000 compares with LINQ.  
(243% slower)

the non-LINQ code:

    for (int i = 0; i &lt; 10000; i++)
    {
        foreach (MyLinqTestClass1 item in lst1) //100000 items in the list
        {
            if (item.Name == &quot;9999&quot;)
            {
                isInGroup = true;
                break;
            }
        }
    }
Took 1443ms to do 1000000000 compares non-LINQ.


LINQ code:      

    for (int i = 0; i &lt; 10000; i++)  
        isInGroup = lst1.Cast&lt;MyLinqTestClass1&gt;().Any(item =&gt; item.Name == &quot;9999&quot;);  


Took 4944ms to do 1000000000 compares with LINQ.

I guess its possible to optimize the LINQ code but the thought was that its easily to get really slow LINQ code and given that it shouldn&#39;t be used. Given that LINQ is slow then it would also follow that PLINQ is slow and NHibernate LINQ would be slow so any kind on LINQ statement should not be used. 

Has anyone else found that LINQ is so slow that they wished they had never used it, or am I making a too general conclusion based on benchmarks like this?

Should LINQ be avoided because it&#39;s slow?

I was wondering if anyone knows how to link an interface xml comment to an implementation. The problem is that I want the base comments to come from my interface first. Example:

    interface myinterface {
        
           /// &lt;summary&gt;
           /// Does something.
           /// &lt;/summary&gt;
           void method1(string foo);

    }

and then the implementation is:

    public class myclass : myinterface {
            
           
           public void method1(string foo) {
                 //do something...
           }
    }

So now if I hover over the method with my mouse after instantiating the object:

    myclass foo = new myclass();
    foo.method1(&quot;do something&quot;);

how can I make the comments appear in the hover popup? Is there some way I can link the interface comments to the implementation? I know there&#39;s a way in Java, but can&#39;t find the solution for C#.

Thanks

How do I display a literal curly brace character when using the String.Format method?

Example:

    sb.AppendLine(String.Format(&quot;public {0} {1} { get; private set; }&quot;, 
    prop.Type, prop.Name));

I would like the output to look like this:

    public Int32 MyProperty { get; private set; }

I tried to truncate a table with foreign keys and got the message:

&gt; &quot;**Cannot truncate table  because it is being referenced by a FOREIGN KEY constraint**&quot;. 

I read a lot of literature about the problem and thought that I found the solution by using delete 

    DELETE FROM table_name DBCC CHECKIDENT (table_name, RESEED, 0)

But I still got an error message:

&gt; &quot;**The DELETE statement conflicted with the REFERENCE constraint**&quot;. 

When I try to delete with Microsoft Management Studio and execute the previous query 
    
    DELETE FROM table_name DBCC CHECKIDENT (table_name, RESEED, 0)

it doesn&#39;t give an error and works properly. I want to delete all information from a table and add new into it, but I don&#39;t want to drop and create foreign keys.

I have the following comma-separated string that I need to split. The problem is that some of the content is within quotes and contains commas that shouldn&#39;t be used in the split.

String:

    111,222,&quot;33,44,55&quot;,666,&quot;77,88&quot;,&quot;99&quot;

I want the output:

	111  
	222  
	33,44,55  
	666  
	77,88  
	99  

I have tried this:  

	(?:,?)((?&lt;=&quot;)[^&quot;]+(?=&quot;)|[^&quot;,]+)   
	
But it reads the comma between &quot;77,88&quot;,&quot;99&quot; as a hit and I get the following  output:  

	111  
	222  
	33,44,55  
	666  
	77,88  
	,  
	99

I want to iterate over some DOM elements, I&#39;m doing this:

    document.getElementsByClassName( &quot;myclass&quot; ).forEach( function(element, index, array) {
      //do stuff
    });

but I get an error:

&gt; document.getElementsByClassName(&quot;myclass&quot;).forEach is not a function

I am using Firefox 3 so I know that both `getElementsByClassName` and `Array.forEach` are present. This works fine:

    [2, 5, 9].forEach( function(element, index, array) {
      //do stuff
    });

Is the result of `getElementsByClassName` an Array? If not, what is it?

1. How does the above for-each loop work?
2. How do I get an iterator for an array in Java?
3. Is the array converted to a list to get the iterator?

Bash foreach loop

Does it make sense to you to use for every normal foreach a parallel.foreach loop ?

When should I start using parallel.foreach, only iterating 1,000,000 items?

Should I always use Parallel.Foreach because more threads MUST speed up everything?

I am trying to skip to the next iteration of the loop if certain conditions are not met. The problem is that the loop is continuing regardless.

Where have I gone wrong?

Updated Code sample in response to first comment.

        foreach ($this-&gt;routes as $route =&gt; $path) {
			$continue = 0;

			...

			// Continue if route and segment count do not match.
			if (count($route_segments) != $count) {
				$continue = 12;
				continue;
			}

			// Continue if no segment match is found.
			for($i=0; $i &lt; $count; $i++) {
				if ($route_segments[$i] != $segments[$i] &amp;&amp; ! preg_match(&#39;/^\x24[0-9]+$/&#39;, $route_segments[$i])) {
					$continue = 34;
					continue;
				}
			}

			echo $continue; die(); // Prints out 34

Erg, I&#39;m trying to find these two methods in the BCL using Reflector, but can&#39;t locate them. What&#39;s the difference between these two snippets?

A:

    IEnumerable&lt;string&gt; items = ...
    
    Parallel.ForEach(items, item =&gt; {
       ...
    });

B:

    IEnumerable&lt;string&gt; items = ...
    
    foreach (var item in items.AsParallel())
    {
       ...
    }

Are there different consequences of using one over the other? (Assume that whatever I&#39;m doing in the bracketed bodies of both examples is thread safe.)


Parallel.ForEach() vs. foreach(IEnumerable&lt;T&gt;.AsParallel())

I am looking for ways to run test suites in parallel. 

I am aware of  &lt;Execution parallelTestCount=&quot;0&quot;&gt; `.testrunconfig` setting. This allows you to **multiplex** on the number of CPUs. 

I want to run 1000 tests in parallel. This makes sense because I am testing a web service, so 90% of the time spent in a test is waiting for the service to respond. 

Any ideas on how to pull this off ? The tests are written for VS, but I am open to running them outside of VS. 

**Later edit**: the Visual Studio test team have added this in VS 2015 Update 1. See Mark Sowul&#39;s answer bellow. 



How to run unit tests (MSTest) in parallel?

I was wondering if there is a [Parallel.For](http://msdn.microsoft.com/en-us/magazine/cc163340.aspx) equivalent to the .net version for Java?

If there is could someone please supply an example? thanks!


&quot;Parallel.For&quot; for Java?

I have a powershell script to do some batch processing on a bunch of images and I&#39;d like to do some parallel processing.  Powershell seems to have some background processing options such as start-job, wait-job, etc, but the only good resource I found for doing parallel work was writing the text of a script out and running those ([PowerShell Multithreading][1])

Ideally, I&#39;d like something akin to parallel foreach in .net 4.

Something pretty seemless like:

    foreach-parallel -threads 4 ($file in (Get-ChildItem $dir))
    {
       .. Do Work
    }

Maybe I&#39;d be better off just dropping down to c#...
