给线程传递参数. 

 1 public class ThreadWithState {
 2         //要传递的参数.
 3         private string boilerplate;
 4         private int value;
 5         //通过构造函数传递参数.
 6         public ThreadWithState(string text, int number) {
 7             boilerplate = text;
 8             value = number;
 9         }
10         //给线程执行的方法，本处返回类型为void是为了能让ThreadStart来直接调用.
11         public void ThreadProc() {
12             //要执行的任务,本处只显示一下传入的参数
13             Console.WriteLine(boilerplate, value);
14         }
15     }
16 
17 public class Example {
18         public static void Main() {
19             //实例化ThreadWithState类，为线程提供参数
20             ThreadWithState tws = new ThreadWithState(
21             "This report displays the number {0}.", 42);
22             // 创建执行任务的线程，并执行
23             Thread t = new Thread(new ThreadStart(tws.ThreadProc));
24             t.Start();
25             Console.WriteLine("Main thread does some work, then waits.");
26             t.Join();
27             Console.WriteLine(
28             "Independent task has completed; main thread ends.");
29         }
30     }
