You can also use a the CallContext if you have some data that you want to "flow" some data with your call sequence. Here is a good blog posting about LogicalCallContext from Jeff Richter.

using System;  
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading; 

namespace ConsoleApplication1 
{ 
  class Program 
  { 
    static void Main(string[] args) 
    { 
        Console.WriteLine("Taking data from Main Thread\n->"); 
        string message = Console.ReadLine(); 

        //Put something into the CallContext
        CallContext.LogicalSetData("time", DateTime.Now);

        ThreadStart newThread = new ThreadStart(delegate { Write(message); }); 

        Thread myThread = new Thread(newThread); 

    } 

    public static void Write(string msg) 
    { 
        Console.WriteLine(msg); 
        //Get it back out of the CallContext
        Console.WriteLine(CallContext.LogicalGetData("time"));
        Console.Read(); 
    } 
  } 
}
