Can a C# Thread start on a non-static member function of a
specific instance of a class, like
System.Threading.Thread mythread ...
mythread.Start(new System.Threading.ThreadStart
(this.MyNonStaticFunc)


Or does it have to start on a static member function of
the class itself, like C++?

Bonj,

It can start on a method of an instance. Basically, you need a
delegate, which is a type safe way of referring to a method. This method
can be an instance method, or a static method, it does not matter. As long
as the signature matches the ThreadStart delegate, then it can be used.

Hope this helps.

System.Threading.Thread mythread ...
mythread.Start(new System.Threading.ThreadStart
(this.MyNonStaticFunc)

Absolutely. For example:

using System;
using System.Threading;

public class Test
{
int counter;

Test(int counter)
{
this.counter=counter;
}

void Count()
{
for (int i=0; i < counter; i++)
{
Console.WriteLine (i);
Thread.Sleep(100);
}
}

static void Main()
{
Test t1 = new Test (5);
Test t2 = new Test (10);

new Thread (new ThreadStart(t1.Count)).Start();
new Thread (new ThreadStart(t2.Count)).Start();
}
}

That's what I want to do! thanks

This seems like one of the ways in which C# is actually
more powerful than C++ then, as C++ can only start a
thread on a global or static method - is it?

Are there any other nifty things like this in which C# is
more powerful than C++?
