passing parameter to thread ??

cmrchs

Hi,

Is there a way to pass a parameter to a thread ?

Creating a thread is done using a ThreadStart-delegate object

example :
Thread thread1 = new Thread(new ThreadStart(MyF unction))

Unfortunately, it doesn't allow me to pass arguments to MyFunction since the definition of the ThreadStart is :
public delegate void ThreadStart();

Is there a way, anyhow, to pass a parameter to a thread ?
Using some other mechanism ?

thnx
Christian

Also, in .NET 2.0, the Thread class has an overloads for the constructor
and the Start methods to allow for the ParameterizedTh readStart delegate,
which allows a parameter to be passed to the thread routine.

Oh, nice - cheers, I'll add looking into that onto my list of things to
do for the multithreading pages :)
