Like this:

    &lt;p&gt;
        @Html.Action(MVC.MeetingActions.ListActions(Model.MeetingId))
    &lt;/p&gt;

or if you insist on `RenderAction` like this:


    &lt;p&gt;
        @{Html.RenderAction(MVC.MeetingActions.ListActions(Model.MeetingId));}
    &lt;/p&gt;

Personally I prefer the first, makes fewer keystrokes.

[Html.Partial][1] should work as well :)

    @Html.Partial(&quot;View&quot;, Model);

I had the same issue. What worked for me is to encapsulate the expression it in **curly brackets**. 

`@{Html.RenderPartial(&quot;viewName&quot;, Model);}`

How can I remove a line (or lines) of a matplotlib axes in such a way as it actually gets garbage collected and releases the memory back?  The below code appears to delete the line, but never releases the memory (even with explicit calls to `gc.collect()`)

    from matplotlib import pyplot
    import numpy
    a = numpy.arange(int(1e7))
    # large so you can easily see the memory footprint on the system monitor.
    fig = pyplot.Figure()
    ax  = pyplot.add_subplot(1, 1, 1)
    lines = ax.plot(a) # this uses up an additional 230 Mb of memory.
    # can I get the memory back?
    l = lines[0]
    l.remove()
    del l
    del lines
    # not releasing memory
    ax.cla() # this does release the memory, but also wipes out all other lines.

So is there a way to just delete one line from an axes and get the memory back?
[This potential solution](https://stackoverflow.com/questions/2732578/delete-lines-in-matplotlib) also does not work.

I&#39;m new to .Net 4.0&#39;s Tasks and I wasn&#39;t able to find what I thought would be a Task based replacement or implementation of a Timer, e.g. a periodic Task. Is there such a thing?

***Update***
I came up with what I think is a solution to my needs which is to wrap the &quot;Timer&quot; functionality inside a Task with child Tasks all taking advantage of the CancellationToken and returns the Task to be able to participate in further Task steps.  

    public static Task StartPeriodicTask(Action action, int intervalInMilliseconds, int delayInMilliseconds, CancellationToken cancelToken)
    { 
        Action wrapperAction = () =&gt;
        {
            if (cancelToken.IsCancellationRequested) { return; }
    
            action();
        };
    
        Action mainAction = () =&gt;
        {
            TaskCreationOptions attachedToParent = TaskCreationOptions.AttachedToParent;
    
            if (cancelToken.IsCancellationRequested) { return; }
    
            if (delayInMilliseconds &gt; 0)
                Thread.Sleep(delayInMilliseconds);
    
            while (true)
            {
                if (cancelToken.IsCancellationRequested) { break; }
    
                Task.Factory.StartNew(wrapperAction, cancelToken, attachedToParent, TaskScheduler.Current);
    
                if (cancelToken.IsCancellationRequested || intervalInMilliseconds == Timeout.Infinite) { break; }
    
                Thread.Sleep(intervalInMilliseconds);
            }
        };
    
        return Task.Factory.StartNew(mainAction, cancelToken);
    }      



Is there a Task based replacement for System.Threading.Timer?

I have the following controller action:

    [ChildActionOnly]
    public virtual PartialViewResult ListActions(int id)
    {
        var actions = meetingActionRepository.GetAllMeetingActions(id);
            
        return PartialView(actions);
    }

And the following action link (using t4MVC and the razor syntax)

    &lt;p&gt;
       @Html.RenderAction(MVC.MeetingActions.ListActions(Model.MeetingId))
    &lt;/p&gt;


However this gives me the error:

&gt;cannot implicitly convert type void to object

As far as i can tell the controller action is ok, so what could be giving me this error?

When I create a new project, I get a strange behavior for unhandled exceptions. This is how I can reproduce the problem:

1) create a new Windows Forms Application (C#, .NET Framework 4, VS2010)

2) add the following code to the `Form1_Load` handler:

    int vara = 5, varb = 0;
    int varc = vara / varb;
    int vard = 7;

I would expect that VS breaks and shows an unhandled exception message at the second line. However, what happens is that the third line is just skipped without any message and the application keeps running.

I don&#39;t have this problem with my existing C# projects. So I guess that my new projects are created with some strange default settings.

Does anyone have an idea what&#39;s wrong with my project???

I tried checking the boxes in Debug-&gt;Exceptions. But then executions breaks even if I handle the exception in a `try-catch` block; which is also not what I want. If I remember correctly, there was a column called &quot;unhandled exceptions&quot; or something like this in this dialog box, which would do excatly what I want. But in my projects there is only one column (&quot;Thrown&quot;).

VS2010 does not show unhandled exception message in a WinForms Application on a 64-bit version of Windows

I&#39;m trying to call `System.Windows.Threading.Dispatcher.BeginInvoke`. The signature of the method is this:

    BeginInvoke(Delegate method, params object[] args)

I&#39;m trying to pass it a Lambda instead of having to create a Delegate.

    _dispatcher.BeginInvoke((sender) =&gt; { DoSomething(); }, new object[] { this } );

It&#39;s giving me a compiler error saying that I 

&gt; can&#39;t convert the lambda to a System.Delegate. 

The signature of the delegate takes an object as a parameter and returns void. My lambda matches this, yet it&#39;s not working. What am I missing?

So sometimes I want to include only one class from a namespace rather than a whole namespace, like the example here I create a alias to that class with the using statement:

    using System;
    using System.Text;
    using Array = System.Collections.ArrayList;

I often do this with generics so that I don&#39;t have to repeat the arguments:

    using LookupDictionary = System.Collections.Generic.Dictionary&lt;string, int&gt;;

Now I want to accomplish the same with a generic type, while preserving it as a generic type:

    using List&lt;T&gt; = System.Collections.Generic.List&lt;T&gt;;

But that doesn&#39;t compile, so is there any way to achieve creating this alias while leaving the type as generic?

Using a &#39;using alias = class&#39; with generic types?

    public class PricePublicModel
    {
        public PricePublicModel() { }

        public double Size2 { get; set; }
        public int[] PrintType { get; set; }
        public double[] Price { get; set; }
    }

    List&lt;PricePublicModel&gt; pricePublicList = new List&lt;PricePublicModel&gt;();



How to check if element of `pricePublicList` contains certain value. To be more precise, I want to check if there exists `pricePublicModel.Size == 200`? Also, if this element exists, how to know which one it is?


EDIT If Dictionary is more suitable for this then I could use Dictionary, but I would need to know how :)

I&#39;m attempting to create a strongly-typed view based on a class from another assembly. For whatever reason though, my Razor view doesn&#39;t seem to have any visibility of other assemblies referenced on my project. e.g.

    @model MyClasses.MyModel

results in the error in Visual Studio 2010, &quot;The type or namespace name `MyClasses` could not be found (are you missing a using directive or an assembly reference?).&quot;

The same class referenced in the standard view engine works fine. I have the same trouble trying to reference the class in the body of my view.

Am I missing something about Razor or do I need to reference the assembly some other way?

I&#39;m currently developing a site using ASP.Net MVC3 with Razor. Inside the &quot;View/Shared&quot; folder, I want to add a subfolder called &quot;Partials&quot; where I can place all of my partial views (for the sake of organizing the site better.

I can do this without a problem as long as I always reference the &quot;Partials&quot; folder when calling the views (using Razor):

    @Html.Partial(&quot;Partials/{ViewName}&quot;)

My question is if there is a way to add the &quot;Partials&quot; folder to the list that .Net goes through when searching for a view, this way I can call my view without having to reference the &quot;Partials&quot; folder, like so:

    @Html.Partial(&quot;{ViewName}&quot;)

Thanks for the help!

I am trying to use ViewBag in my application, I have all of the recent dlls, the latest version of MVC 3, but yet I am still getting the Error:
&gt;&quot;The name &#39;ViewBag&#39; does not exist in the current context&quot;

I have even uninstalled and then re-installed MVC 3 and yet there is no change. 

Also, I do not believe that the dll&#39;s are showing up in the GAC. 

What might be my problem? Or how to add the dll&#39;s to the GAC?

I have a razor view that I added a delete button to inside of an &#39;if&#39; statement and when the view is rendered in the browser it is displaying **&quot;System.Web.Mvc.Html.MvcForm&quot;** next to the delete button. 

How do I get rid of it?

Here is the code:

    &lt;div id=&quot;deletestatusupdate&quot;&gt;
        @if (update.User.UserName.Equals(User.Identity.Name, StringComparison.OrdinalIgnoreCase))

            &lt;button name=&quot;id&quot; value=&quot;@update.StatusUpdateId&quot;&gt;Delete&lt;/button&gt;
        }
    &lt;/div&gt;

**Here is how it shows up in the rendered Razor View:**
