Examples
The following example demonstrates how to use the IsAlive property.
public static void TestThreadProperties(DTE 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(EnvDTE.Thread thread in threads)
{
owp.OutputString("\nThread: " + thread.ID + " Name: " + thread.Name);
owp.OutputString("\n Edition of the environment : " + thread.DTE.Edition);
owp.OutputString("\n Is alive : " + thread.IsAlive);
owp.OutputString("\n Is frozen : " + thread.IsFrozen);
owp.OutputString("\n Location : " + thread.Location);
owp.OutputString("\n Parent's current mode : " + thread.Parent.CurrentMode);
owp.OutputString("\n Priority : " + thread.Priority);
owp.OutputString("\n Program name : " + thread.Program.Name);
owp.OutputString("\n Number of stack frames : " + thread.StackFrames.Count);
owp.OutputString("\n Suspended number of times : " + thread.SuspendCount);
}
}

Remarks
Returns true
if the referenced thread is still alive; otherwise, false
.
