问题描述
在下面的代码中，我需要知道在引发事件时传递两个字符串的语法.
In the following code I need to know the syntax of passing two strings when the event is raised.

public event EventHandler<EventArgs<string>> MyEvent;
谢谢，撒克逊人.
推荐答案
最简洁的方法是创建自己的类，该类派生自 EventArgs:
The cleanest way is to create your own class that derives from EventArgs:
public class MyEventArgs : EventArgs
{
private readonly string _myFirstString;
private readonly string _mySecondString;
public MyEventArgs(string myFirstString, string mySecondString)
{
_myFirstString = myFirstString;
_mySecondString = mySecondString;
}
public string MyFirstString
{
get { return _myFirstString; }
}
public string MySecondString
{
get { return _mySecondString; }
}
}
并像这样使用它:
public event EventHandler<MyEventArgs> MyEvent;
要引发事件，您可以执行以下操作:
To raise the event, you can do something like this:
protected virtual void OnMyEvent(string myFirstString, string mySecondString)
{
EventHandler<MyEventArgs> handler = MyEvent;
if (handler != null)
handler(this, new MyEventArgs(myFirstString, mySecondString));
}
