使用lambda的简单方法是这样的..

Thread t = new Thread(() => DoSomething("param1", "param2"));
t.Start();

或者你甚至可以像这样使用ThreadStart委托…

private void DoSomething(int param1, string param2)
{
    //DO SOMETHING...
    ThreadStart ts = delegate
    {
        if (param1 > 0) DoSomethingElse(param2, "param3");
    };   
    new Thread(ts).Start();
    //DO SOMETHING...
}

或者使用。net 4.5+甚至更干净，像这样..

private void DoSomething(int param1, string param2)
{
    //DO SOMETHING..
    void ts()
    {
        if (param1 > 0) DoSomethingElse(param2, "param3");
    }
    new Thread(ts).Start();
    //DO SOMETHING..
}

class Program
{
    static void Main(string[] args)
    {
        Thread t = new Thread(new ParameterizedThreadStart(ThreadMethod));

        t.Start("My Parameter");
    }

    static void ThreadMethod(object parameter)
    {
        // parameter equals to "My Parameter"
    }
}

Thread构造函数的两个重载之一采用ParameterizedThreadStart委托，允许您将单个参数传递给start方法。不幸的是，虽然它只允许一个参数，它这样做的方式是不安全的，因为它传递作为对象。我发现使用lambda表达式捕获相关参数并以强类型的方式传递它们要容易得多。

试试下面的方法

public Thread StartTheThread(SomeType param1, SomeOtherType param2) {
  var t = new Thread(() => RealStart(param1, param2));
  t.Start();
  return t;
}

private static void RealStart(SomeType param1, SomeOtherType param2) {
  ...
}

使用lambda表达式的一种非常简单和方便的方式是这样的:

Thread thread = new Thread( (param) => {
    string name = param as string;
    // rest of code goes here.
});
thread.Start("MyName");

通过这种方式，lambda表达式可以具有参数并在单独的线程中运行内联代码。

使用lambda的简单方法是这样的..

Thread t = new Thread(() => DoSomething("param1", "param2"));
t.Start();

    };   
    new Thread(ts).Start();
    //DO SOMETHING...
