在c＃中===的目的 [英] Purpose Of === in c#

问题描述

我是c＃的新手。我需要知道c＃中===操作的目的。任何人都可以解释我简单。谢谢你提前。

解决方案

看起来你错误地将JavaScript用于C＃。我怀疑你已经看到C＃代码将JavaScript注入Web客户端页面 - 因此你会看到 === 。在JavaScript中， === 运算符测试身份相等性。使用此运算符不进行类型转换。

C＃中没有此类运算符。请参阅 - C＃操作员 [ ^ ]，其中列出了所有可用的运算符。



但是此运算符在 JavaScript 中可用。

参考 - JavaScript比较和逻辑运算符 [ ^ ]

Quote：

===完全等于（等值和等于类型）



x ===5false

x === 5 true

因此，它会检查 DataType 以及值。

c＃中没有===运算符。



以下是所有C＃运算符的列表： http://msdn.microsoft.com/e n-us / library / 6a71f45d.aspx [ ^ ]

解决方案

It looks like you're mistaking JavaScript for C#. I suspect that you have seen C# code injecting JavaScript into a web client page - hence where you would have seen ===. In JavaScript, the === operator tests for identity equality. No type conversion is done with this operator.

There is no such operator in C#. Refer - C# Operators[^], which list all the available operators.

But this operator is available in JavaScript.
Refer - JavaScript Comparison and Logical Operators[^]

Quote:

=== exactly equal to (equal value and equal type)

x==="5" false
x===5 true

So, it checks the DataType as well as value.

There is no === operator in c#.

Here is a list of all C# operators: http://msdn.microsoft.com/en-us/library/6a71f45d.aspx[^]
