I don't know what are you up to. But here are some of the sample codes to clarify you how threading works.
Class Test
{
static void main()
{
Thread t=new Thread(WriteB);
t.Start();
for(int i=0; i<1000; i++)
{
Console.Write("A");
}
}
static void WriteB()
{
for (int(i=0; i<1000; i++)
{
Console.Write("Y");
}
}
}
I hope this would help you.
If you have any confusion, you are free to ask me.
