C # Multithreading Creation __c#

Find the problem, don't know right or wrong, or why

C # in the use of multithreading, when the number of generated threads is very high, can not be directly generated in the main thread, but the need to create a thread, and then in the newly created thread to start more threads

Example:

Main thread .....

for (int i = 0; i < list. Count; i++)
{


Thread th = new Thread (new Parameterizedthreadstart (Fnthread));
Th. Start ();


}

Main thread .....

This will cause multithreading to not start properly

Need to read

Main thread .....

Thread th = new Thread (new Parameterizedthreadstart (Fnthreadstart));
Th. Start ();

Main thread .....

void Fnthreadstart ()

{

for (int i = 0; i < list. Count; i++)
{


Thread th = new Thread (new Parameterizedthreadstart (Fnthread));
Th. Start ();


}

}
