The creating thread must specify the starting address of the code that the new thread is to execute. Typically, the starting address is the name of a function defined in the program code (for more information, see ThreadProc). This function takes a single parameter and returns a DWORD value. A process can have multiple threads simultaneously executing the same function. The following is a simple example that demonstrates how to create a new thread that executes the locally defined function, MyThreadFunction. The calling thread uses th

Comment 2 Mark Probst 2014-04-02 18:27:34 UTC The problem here is that tasks get allocated very quickly, but they complete incredibly slowly. With the original test case, it seems that no task ever completes, in fact. I have modified it a bit, to count started and completed tasks, and to do fewer iterations in the tasks: using System; using System.Threading.Tasks; class MainClass { static object completedLocker = new Object (); static long started = 0; static long completed = 0; public static void Main (string[] args) { int j = 0; while (true) { Task.Run (() => { string s = ""; for (int i = 0; i < 20000; ++i) { s += i.ToString (); } lock (completedLocker) { ++completed; } }); ++started; if ((++j % 100) == 0) { long c = 0; lock (completedLocker) { c = completed; } Console.WriteLine ("started " + started + " completed " + c); } } } } After about 10 seconds, this program gets to started 3649200 completed 86 With Boehm, it gets to started 108300 completed 233 If we want this program to run, we will probably need to throttle threadpool enqueuing.

[duplicate] up vote 0 down vote favorite This question already has an answer here: problems using CreateThread on a member createthread error creating function 1 answer I tried to create a thread inside of a class and I got an error. I'm just wondering if there is way around this or must I use threads within int main() only?
