Try this:

    System.Reflection.MethodBase.GetCurrentMethod().Name 

You can check the stack trace

    using System.Diagnostics;
    
    // get call stack
    StackTrace stackTrace = new StackTrace();
    
    // get calling method name
    Console.WriteLine(stackTrace.GetFrame(0).GetMethod().Name);

But beware, if the method is inlined you get the parent method name.

I&#39;m becoming crazy figuring out what is the best way to handle screen rotation. I read hundreds of questions/answers here but I&#39;m really confused.

How can I save myClass data before the activity is re-created so I can keep everything for redrawing activity without another useless initialization?

Is there a cleaner and better way than parcelable?

I need to handle rotation because I want to change layout in Landscape mode.


    public class MtgoLifecounterActivity extends Activity {
    	
		MyClass myClass;
	
		// Called when the activity is first created
		@Override
	    public void onCreate(Bundle savedInstanceState) {
	        super.onCreate(savedInstanceState);
	        setContentView(R.layout.main);
	 		
			If ( ?? first run...myClass == null ? ) {
				myClass = new MyClass();
			} else {
				// do other stuff but I need myClass istance with all values.
			}
			// I want that this is called only first time. 
			// then in case of rotation of screen, i want to restore the other instance of myClass which
			// is full of data.
	    }

I&#39;m playing with these Windows 8 WinRT tasks, and I&#39;m trying to cancel a task using the method below, and it works to some point. The CancelNotification method DOES get called, which makes you think the task was cancelled, but in the background the task keeps running, then after it&#39;s completed, the status of the Task is always completed and never cancelled. Is there a way to completely halt the task when it&#39;s cancelled?


    private async void TryTask()
    {
        CancellationTokenSource source = new CancellationTokenSource();
        source.Token.Register(CancelNotification);
        source.CancelAfter(TimeSpan.FromSeconds(1));
        var task = Task&lt;int&gt;.Factory.StartNew(() =&gt; slowFunc(1, 2), source.Token);
    
        await task;            
    
        if (task.IsCompleted)
        {
            MessageDialog md = new MessageDialog(task.Result.ToString());
            await md.ShowAsync();
        }
        else
        {
            MessageDialog md = new MessageDialog(&quot;Uncompleted&quot;);
            await md.ShowAsync();
        }
    }
    
    private int slowFunc(int a, int b)
    {
        string someString = string.Empty;
        for (int i = 0; i &lt; 200000; i++)
        {
            someString += &quot;a&quot;;
        }
    
        return a + b;
    }
    
    private void CancelNotification()

I have two DLL files which I&#39;d like to include in my EXE file to make it easier to distribute it. I&#39;ve read a bit here and there how to do this, even found a good thread [here][1], and [here][2], but it&#39;s far too complicated for me and I need real basic instructions on how to do this.

I&#39;m using Microsoft Visual C# Express 2010, and please excuse my &quot;low standard&quot; question, but I feel like I&#39;m one or two level below everyone else&#39;s expercise :-/ If someone could point out how to merge these DDL files into my EXE in a step-by-step guide, this would be **really** awesome!

Does the .net function [Parallel.ForEach][1] block the calling thread? My guess as to the behavior is one of these:

 1. Yes, it blocks until the slowest item executing returns.
 2. No, it doesn&#39;t block and returns control immediately. The items to run in parallel are done on background threads.

Or perhaps something else is happening, anyone know for sure?

This question came up when implementing this in a logging class:

    public class MultipleLoggingService : LoggingServiceBase
    {
        private readonly List&lt;LoggingServiceBase&gt; loggingServices;

        public MultipleLoggingService(List&lt;LoggingServiceBase&gt; loggingServices)
        {
            this.loggingServices = loggingServices;
            LogLevelChanged += OnLogLevelChanged;
        }

        private void OnLogLevelChanged(object sender, LogLevelChangedArgs args)
        {
            loggingServices.ForEach(l =&gt; l.LogLevel = LogLevel);
        }

        public override LogMessageResponse LogMessage(LogMessageRequest request)
        {
            if (request.LogMessage)
                Parallel.ForEach(loggingServices, l =&gt; l.LogMessage(request));

            return new LogMessageResponse{MessageLogged = request.LogMessage};
        }
    }

Notice the `LogMessage` method calls some other logging services. I need that part to return immediately, so it doesn&#39;t block the calling thread.


-----------------------
Update: Based on comments from others (we have confirmed the behavior is #1). So I have taken advice to use the [Task][2] library and rewritten the loop like this:

              if (request.LogMessage)
                foreach (var loggingService in loggingServices)
                    Task.Factory.StartNew(() =&gt; loggingService.LogMessage(request));

What is the most modern (best) way of satisfying the following in C#?

    string encryptedString = SomeStaticClass.Encrypt(sourceString);
    
    string decryptedString = SomeStaticClass.Decrypt(encryptedString);

BUT with a minimum of fuss involving salts, keys, mucking about with byte[], etc.

Been Googling and confused at what I&#39;m finding (you can see the list of similar SO Qs to see this is a deceptive question to ask).

I have a homework to build an application which will send and receive simple string between server and client. I know how to establish connection, but don&#39;t know how to send and receive string. This is my code : 

    public partial class Form1 : Form
    {
        private Thread n_server;
        private Thread n_client;
        private Thread n_send_server;

        private int port = 2222;
        private string IP = &quot; &quot;;
        private Socket socket;
        public Form1()
        {
            InitializeComponent();
        }

        private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

        public void Server()
        {
            listener = new TcpListener(IPAddress.Any, port);
            listener.Start();
            try
            {
                socket = listener.AcceptSocket();

        {
            IP = &quot;localhost&quot;;
            client = new TcpClient();
            try

                textBox3.Invoke((MethodInvoker)delegate { textBox3.Text = &quot;Connected...&quot;; });

            }

            // on client side. First I read text from textbox2 on server side or textbox3
            // on client side than accept and write the string to label2(s) or label3(c).

I&#39;ve seen [a lot of talk about running Mono/.NET code on the Raspberry Pi][1]. Has there been any success in actually running any Mono code on a Raspberry Pi?

On their site, they list several Linux distributions that work on the device and some of these distributions include Mono. However, none detail whether Mono works on it.

Is there a working implementation?

Given the following enum:

    public enum Operations_PerHourType : byte
    {
        Holes = 1,
        Pieces = 2,
        Sheets = 3,
        Strips = 4,
        Studs = 5
    }

When I run the Microsoft code analysis tool, it tells me:

&gt; CA1028 : Microsoft.Design : If possible, make the underlying type of &#39;Enums.Operations_PerHourType&#39; System.Int32 instead of &#39;byte&#39;.	

It will never have more than a couple possible values, so I declared it as a byte.  Why would they recommend using int32?  More values for future scalability? Or is there a performance improvement?

Why should I make the underlying type of an Enum Int32 instead of byte?

It says in AssemblyInfo.cs for C# projects that it&#39;s possible to specify version information with `*`

    // Version information for an assembly consists of the following four values:
    //
    //      Major Version
    //      Minor Version 
    //      Build Number
    //      Revision
    //
    // You can specify all the values or you can default the Revision and Build Numbers 
    // by using the &#39;*&#39; as shown below:
    [assembly: AssemblyVersion(&quot;1.0.0.0&quot;)]
    [assembly: AssemblyFileVersion(&quot;1.0.0.0&quot;)]

I changed it to this:

    [assembly: AssemblyVersion(&quot;1.0.*.*&quot;)]
    [assembly: AssemblyFileVersion(&quot;1.0.*.*&quot;)]

and this is the error I get from the compiler:

    error CS0647: Error emitting &#39;System.Reflection.AssemblyVersionAttribute&#39; attribute -- &#39;The version specified &#39;1.0.*.*&#39; is invalid&#39;
    warning CS1607: Assembly generation -- The version &#39;1.0.*.*&#39; specified for the &#39;file version&#39; is not in the normal &#39;major.minor.build.revision&#39; format

How does (does it even?) it work?
