copied!<p>I would punt on getting the file name. It can be done, but it is probably not worth the effort. Instead, set the <code>Name</code> property on the <code>Thread</code> to the name of the class that created it.</p> <p>You will be able to see the <code>Name</code> value when inspected with the Visual Studio debugger. If you want to get a list of all managed threads in the current process via code then you will need to create your own thread repository. You cannot map a <code>ProcessThread</code> to a <code>Thread</code> because there is not always a one-to-one relationship between the two.</p> <pre><code>public static class ThreadManager { private List<Thread> threads = new List<Thread>(); public static Thread StartNew(string name, Action action) { var thread = new Thread( () => { lock (threads) { threads.Add(Thread.CurrentThread); } try { action(); } finally { lock (threads) { threads.Remove(Thread.CurrentThread); } } }); thread.Name = name; thread.Start(); } public static IEnumerable<Thread> ActiveThreads { get { lock (threads) { return new List<Thread>(threads); } } } } </code></pre> <p>And it would be used like this.</p> <pre><code>class SomeClass { public void StartOperation() { string name = typeof(SomeClass).FullName; ThreadManager.StartNew(name, () => RunOperation()); } } </code></pre> <p><strong>Update:</strong></p> <p>If you are using C# 5.0 or higher you can experiment with the new <a href="http://msdn.microsoft.com/en-us/library/hh534540.aspx" rel="nofollow">Caller Information</a> attributes.</p> <pre><code>class Program { public static void Main() { DoSomething(); } private static void DoSomething() { GetCallerInformation(); } private static void GetCallerInformation( [CallerMemberName] string memberName = "", [CallerFilePath] string sourceFilePath = "", [CallerLineNumber] int sourceLineNumber = 0) { Console.WriteLine("Member Name: " + memberName); Console.WriteLine("File: " + sourceFilePath); Console.WriteLine("Line Number: " + sourceLineNumber.ToString()); } } </code></pre>
