<para>When a managed thread is created, the method that executes on the thread is represented by a <see cref="T:System.Threading.ThreadStart" /> delegate or a <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate that is passed to the <see cref="Overload:System.Threading.Thread.#ctor" /> constructor. The thread does not begin executing until the <see cref="Overload:System.Threading.Thread.Start" /> method is called. The <see cref="T:System.Threading.ThreadStart" /> or <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate is invoked on the thread, and execution begins at the first line of the method represented by the delegate. In the case of the <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate, the object that is passed to the <see cref="M:System.Threading.Thread.Start(System.Object)" /> method is passed to the delegate. </para>
<block subset="none" type="note">
<para>Visual Basic and C# users can omit the <see cref="T:System.Threading.ThreadStart" /> or <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate constructor when creating a thread. In Visual Basic, use the AddressOf operator when passing your method to the <see cref="Overload:System.Threading.Thread.#ctor" /> constructor; for example, Dim t As New Thread(AddressOf ThreadProc). In C#, simply specify the name of the thread procedure. The compiler selects the correct delegate constructor.</para>
</block>
<block subset="none" type="note">
<para>When you create a <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate for an instance method in C++, the first parameter of the constructor is the instance variable. For a static method, the first parameter of the constructor is zero. For a static method, the delegate constructor requires only one parameter: the address of the callback method, qualified by the class name.</para>
</block>
<para>The <see cref="T:System.Threading.ParameterizedThreadStart" /> delegate and the <see cref="M:System.Threading.Thread.Start(System.Object)" /> method overload make it easy to pass data to a thread procedure, but this technique is not type safe because any object can be passed to <see cref="M:System.Threading.Thread.Start(System.Object)" />. A more robust way to pass data to a thread procedure is to put both the thread procedure and the data fields into a worker object.
