Answer 1

Thread thread = new Thread(() => Send(arg1, arg2, arg3));
thread.Start();

Answer 2

this may help. You can define your Send method as follows and then can use the parameters.

string[] parameters = new string[3];
parameters[0] = arg1;
parameters[1] = arg2;
parameters[1] = arg3;

System.Threading.Thread SendingThread = new System.Threading.Thread(Send);
SendingThread.Start(parameters);


public void Send(object parameters)
{
   Array arrayParameters = new object[3];
   arrayParameters = (Array)parameters;
   string str1 = (string)arrayParameters.GetValue(0);
   string str2 = (string)arrayParameters.GetValue(1);
   string str3 = (string)arrayParameters.GetValue(2);

   ///Following code here...
}

Answer 3

You could define a type, that encapsulates the parameters you want to pass and start the thread with a reference to an instance of this type.

Answer 4

You can define an intermediate method and helper object to do this:

public void MethodToCallInThread(string param1, string param2)
{
    ...
}
public void HelperMethod(object helper){
    var h = (HelperObject) helper;
    MethodToCallInThread(h.param1, h.param2);
}

And then you start the thread with the HelperMethod, not with MethodToCallInThread:

var h = new HelperObject { param1 = p1, param2 = p2 }
ThreadPool.QueueUserWorkItem(HelperMethod, h);
