<summary>
<para> Represents errors that occur when a method is invoked on
a <see cref="T:System.Threading.Thread" /> and the
thread is in a <see cref="P:System.Threading.Thread.ThreadState" /> that is
invalid for the method.</para>
</summary>
<remarks>
<para>Once a thread is created, it is in one or more states, as defined
by <see cref="T:System.Threading.ThreadState" />, until it
terminates. <see cref="T:System.Threading.ThreadStateException" /> is
thrown by methods that cannot perform the requested operation due to
the current state of
a thread. For example, calling <see cref="M:System.Threading.Thread.Start" />
on a thread that has terminated results in a <see cref="T:System.Threading.ThreadStateException" /> exception.</para>
</remarks>
<example>
<para>The following example demonstrates an error that causes
a <see cref="T:System.Threading.ThreadStateException" /> exception to be thrown.</para>
<code lang="C#">using System;
using System.Threading;
public class ThreadWork {
public static void DoWork() {
Console.WriteLine("Working thread...");
