如何将对象传递给计时器事件? [英] How do I pass an object into a timer event?

问题描述

好的，所以我在 .Net 4 和 C# 中使用 System.Timers.Timer.

Ok so I am using System.Timers.Timer in .Net 4 with C#.

我有这样的计时器对象:

I have my timer object like so:

var timer = new Timer {Interval = 123};

我的 Timer Elapsed 事件处理程序指向这样的方法:

I have my Timer Elapsed event handler pointed at a method like so:

timer.Elapsed += MyElapsedMethod;

我的方法是这样的:

static void MyElapsedMethod(object sender, ElapsedEventArgs e)
{
    Console.WriteLine("Foo Bar");
}

我想向这个方法传递一个字符串，我该怎么做?

I want to pass a string into this method, how do I do this?

谢谢

推荐答案

最简单的方法是将事件处理程序更改为匿名函数.它允许您在声明点传递字符串.

The easiest way to do this is to change the event handler into an anonymous function. It allows you to pass the string at the point of declaration.

string theString = ...;
timer.Elapsed += (sender, e) => MyElapsedMethod(sender, e, theString);

static void MyElapsedMethod(object sender, ElapsedEventArgs e, string theString) {
  ...
}
