what is the c# equivalent to javascript's unescape()?
提问by vivek a.
I am trying to analyse some JavaScript, and one line is
我正在尝试分析一些JavaScript，其中一行是
var x = unescape("%u4141%u4141 ......");
with lots of characters in form %uxxxx.
形式上有很多字符%uxxxx。
I want to rewrite the JavaScriptin c#but can't figure out the proper function to decode a string of characters like this. I've tried
我想重写JavaScriptinc#但无法找出正确的函数来解码这样的字符串。我试过了
HttpUtility.HTMLDecode("%u4141%u4141");
but this did not change these characters at all.
但这根本没有改变这些字符。
How can I accomplish this in c#?

You can use UrlDecode:
您可以使用UrlDecode：
string decoded = HttpUtility.UrlDecode("%u4141%u4141");
decodedwould then contain "??".
decoded然后将包含"??".
As other have pointed out, changing the %to \would work, but UrlDecodeis the preferred method, since that ensures that other escaped symbols are translated correctly as well.
正如其他人指出的那样，更改%to\会起作用，但UrlDecode它是首选方法，因为这可确保其他转义符号也能正确翻译。

You need HttpUtility.UrlDecode. You shouldn't really be using escape/unescapein most cases nowadays, you should be using things like encodeURI/decodeURI/encodeURIComponent.
你需要HttpUtility.UrlDecode. escape/unescape现在大多数情况下你不应该真的使用，你应该使用像encodeURI/decodeURI/encodeURIComponent.
When are you supposed to use escape instead of encodeURI / encodeURIComponent?
你什么时候应该使用escape而不是encodeURI / encodeURIComponent？
This questioncovers the issue of why escape/unescapeare a bad idea.
这个问题涵盖了为什么escape/unescape是一个坏主意的问题。

You can call bellow method to achieve the same effect as Javascript escape/unescape method
可以调用 bellow 方法来达到与 Javascript 转义/转义方法相同的效果
Microsoft.JScript.GlobalObject.unescape();
Microsoft.JScript.GlobalObject.escape();

Change the % signs to backslashes and you have a C# string literal. C# treats \uxxxx as an escape sequence, with xxxx being 4 digits.
将 % 符号更改为反斜杠，您就有了一个 C# 字符串文字。C# 将 \uxxxx 视为转义序列，其中 xxxx 为 4 位数字。

In basic string usage you can initiate string variable in Unicode: var someLine="\u4141"; If it is possible - replace all "%u" with "\u".
在基本的字符串用法中，您可以在 Unicode 中启动字符串变量： var someLine="\u4141"; 如果可能 - 用“\u”替换所有的“%u”。
