推荐答案

对于this，我有一些帮助您: a href ="http://msdn.microsoft.com/en-us/library/dk1507sz.aspx"> http://msdn.microsoft.com/en-us/library/dk1507sz.aspx [ ^ ]

我咨询该网站 C#关键字 ^ ]没有您在问题中提出的关键字function.

问候，

For this I have something to help you along: http://msdn.microsoft.com/en-us/library/dk1507sz.aspx[^]

I you consult this site C# Keywords[^] you''ll find that there is no such keyword function as you proposed in your question.

"this"关键字的用法是:

要限定隐藏有类似名称的成员.
要使对象将自身作为参数传递给其他方法.
要使对象从方法中返回自身.
声明索引器.
声明扩展方法.
在构造函数之间传递参数.

而且在c#中没有功能"关键字.

希望对您有所帮助:)

Uses of "this" keyword are:

To qualify members hidden by similar name.
To have an object pass itself as a parameter to other methods.
To have an object return itself from a method.
To declare indexers.
To declare extension methods.
To pass parameters between constructors.

and there is no "function" keyword in c#.

hope it helps :)

this:在C#中有几个地方我们使用this，但是主要的地方是显式地引用其中的类的当前实例.一个方法.这使我们能够区分局部方法参数和类级别实例字段或同名属性:

this: There are a couple of places we use this in C#, but the main one is to explicitly refer to the current instance of the class within a method. THis allows us to distinguish between a local method paramter and an class level instance feild or property of the same name:

private string myValue;
void MyMethod(string myValue)
   {
   this.myValue = myValue; //Assigns the value in the method parameter to the class level field.
   }

在this关键字上查看MSDN-它会解释更多. http://msdn.microsoft.com/en-us/library/dk1507sz (v = vs.71).aspx [ http://msdn.microsoft.com/zh-CN -us/library/x53a06bb(v = vs.71).aspx [

Have a look at MSDN on the this keyword - it explains more. http://msdn.microsoft.com/en-us/library/dk1507sz(v=vs.71).aspx[^]
function: We don''t - it isn''t a keyword. See MSDN list of keywords: http://msdn.microsoft.com/en-us/library/x53a06bb(v=vs.71).aspx[^]
