Causes the operating system to change the state of the current instance to ThreadState.Running, and optionally supplies an object containing data to be used by the method the thread executes.
Once a thread is in the ThreadState.Running state, the operating system can schedule it for execution. The thread begins executing at the first line of the method represented by the System.Threading.ThreadStart or System.Threading.ParameterizedThreadStart delegate supplied to the thread constructor.
Once the thread terminates, it cannot be restarted with another call to Start.
This overload and the System.Threading.ParameterizedThreadStart delegate make it easy to pass data to a thread procedure, but the technique is not type safe because any object can be passed to this overload. 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. For more information, see Creating Threads.
