<para>
<see cref="T:System.Threading.WaitCallback" /> represents a callback method that you want to execute on a <see cref="T:System.Threading.ThreadPool" /> thread. Create the delegate by passing your callback method to the <see cref="T:System.Threading.WaitCallback" /> constructor. Your method must have the signature shown here.</para>
<para>Queue your task for execution by passing the <see cref="T:System.Threading.WaitCallback" /> delegate to <see cref="M:System.Threading.ThreadPool.QueueUserWorkItem(System.Threading.WaitCallback,System.Object)" />. Your callback method executes when a thread pool thread becomes available.</para>
<para>[Visual Basic]</para>
<block subset="none" type="note">
<para>Visual Basic users can omit the <see cref="T:System.Threading.WaitCallback" /> constructor, and simply use the AddressOf operator when passing the callback method to <see cref="M:System.Threading.ThreadPool.QueueUserWorkItem(System.Threading.WaitCallback,System.Object)" />. Visual Basic automatically calls the correct delegate constructor.</para>
</block>
<para>If you want to pass information to your callback method, create an object that contains the necessary information and pass it to <see cref="M:System.Threading.ThreadPool.QueueUserWorkItem(System.Threading.WaitCallback,System.Object)" /> when you queue your task for execution. Each time your callback method executes, the <paramref name="state" /> parameter contains this object.</para>
