我在传递参数时有问题。 我将一个整数从for循环传递给函数并显示它，但它总是给出不同的结果。例如(1,2,2,3)(1,2,3,3)(1,1,2,3)等与paramtrizedthreadstart委托。

这个简单的代码很有魔力

Thread thread = new Thread(Work);
thread.Start(Parameter);

private void Work(object param) 
{
 string Parameter = (string)param; 
}

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) {
  ...
}

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 thread = new Thread(Work);
thread.Start(Parameter);

private void Work(object param)
{
    string Parameter = (string)param;
}

参数类型必须为对象。

编辑:

虽然这个答案是正确的，但我不建议使用这种方法。使用lambda表达式更容易阅读，并且不需要类型强制转换。请看这里:https://stackoverflow.com/a/1195915/52551
