Question

I would like to execute a method in a thread. The method has multiple arguments and expects return value. Can anyone help?

Answer 1

Thread thread = new Thread(() => 
       {
          var result = YourMethod(param1, param2);
          // process result here (does not invoked on your main thread)
       });

If you need to return result to main thread, then consider using Task (C# 4) instead:

var task = new Task<ReturnValueType>(() => YourMethod(param1, param2));
task.Start();

// later you can get value by calling task.Result;

Or with previous version of C#

Func<Param1Type, Param2Type, ReturnValueType> func = YourMethod;            
IAsyncResult ar = func.BeginInvoke(param1, param2, null, null);
ar.AsyncWaitHandle.WaitOne();
var result = func.EndInvoke(ar);
