Examples

The following example demonstrates how to use the Collection property.

public static void TestThreadProperties(DTE2 dte)  
{  
    // Setup debug Output window.  
    Window w =   
      (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);  
    w.Visible = true;  
    OutputWindow ow = (OutputWindow)w.Object;  
    OutputWindowPane owp = ow.OutputWindowPanes.Add("Thread Test");  
    owp.Activate();  

    EnvDTE.Threads threads = dte.Debugger.CurrentProgram.Threads;  
    owp.OutputString("\nNumber of items in the Thread collection: " +   
      threads.Item(1).Collection.Count + "\n");  
    foreach(EnvDTE90.Thread2 thread in threads)  
    {  
        owp.OutputString("\nThread: " + thread.ID + "  Name: " +   
          thread.Name);

        owp.OutputString("\n  Is alive                   : " +   
          thread.IsAlive);  
        owp.OutputString("\n  Is frozen                  : " +   
          thread.IsFrozen);  
        owp.OutputString("\n  Location                   : " +
