Thread of a delegate

[C# Programming]

Hi all,

I would like in C# to initialize a thread with a delegate. It looks like this :

internal delegate void MyDelegateType();
internal MyDelegateType MyDelegate;

public Init_Launch_Thread()
{
Thread lThread_Groupe = new Thread(MyDelegate); //Is not allowed
lThread_Groupe.Start();
}


It is not allowed and I do not really get why. My problem is that I do not know before construction of my class what actually will be launched in the thread. Is anyone got an idea ? I would like to avoid polymorphism there for other reasons.
thx
