这是怎么做的：

 这 .MouseMove + =（sender，eventArgs）= >  { //  实际参数t ypes由编译器根据已知事件类型推断 
 //  从此处调用你想要的，使用eventArgs参数 
}; 

即使你工作，你也可以使用匿名方法做同样的事情使用C＃v.2尚未引入lambda表达式：

  this  .MouseMove + = deletage（  object  sender，MouseEventArgs eventArgs）{
 //   ...  
}; 

顺便说一下，永远不要使用像Form1_MouseMove这样的自动生成的名称 - 它们违反（好的）Microsoft命名约定;不要使用下划线，数字等。总是将所有这些名称重命名为语义。您认为重构引擎是什么？

请澄清：你希望在超时后关闭你的应用程序，或者它作为一个错误关闭，你想避免这种情况吗？在第一种情况下，您可以参考这篇文章：应用程序空闲 [ ^ ]，在后一种情况下，您应该发布一些代码。

Hi,

My question is simple, I have created a program, but when there has been 10 minutes of inactivity, the application will Close, like this:

Application.Close();

I already search about Mouse Move event and there come some errors, in my Form1.Designer.cs is an error in this line:

this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.Form1_MouseMove);

The error says:

Cannot assign to 'MouseMove' because it is a 'method group'

Regards,
KZ

This is how to do it:

this.MouseMove += (sender, eventArgs) => { // actual parameter types are inferred by a compiler from the known event type
    // from here, call whatever you want, using eventArgs parameters
};

You can do the same using anonymous method even if you work with C# v.2 where lambda expression were not yet introduced:

this.MouseMove += deletage(object sender, MouseEventArgs eventArgs) { 
    // ...
};

[EDIT]

By the way, never ever use auto-generated names like "Form1_MouseMove" — they violate (good) Microsoft naming conventions; don''t use underscore, numerics, etc. Always rename all such names to something semantic. What do you think refactoring engine for?

Please clarify: you want to close you app after the timeout, or it is closing as a bug, and you want to avoid this? In the first case, you could consult this article: Application Idle[^], in the later case, you should post a little more of your code.
