Threading

A C# application runs in one or more threads that effectively execute in parallel within the same application. Here is a simple multithreaded application:

using System; using System.Threading; class ThreadTest { static void Main( ) { Thread t = new Thread(new ThreadStart(Go)); t.Start( ); Go( ); } static void Go( ) { for (char c='a'; c<='z'; c++ ) Console.Write(c); } }

In this example, a new thread object is constructed by passing it a ThreadStart delegate that wraps the method that specifies where to start execution for that thread. You then start the thread and call Go, so two separate threads are running Go in parallel. However, there’s a problem: both threads share a common resource—the console. If you run ThreadTest, you could get output like this:
