You can use <a href="http://msdn.microsoft.com/en-us/library/system.web.httputility.urldecode.aspx">UrlDecode</a>:

<pre><code>string decoded = HttpUtility.UrlDecode("%u4141%u4141");
</code></pre>

<code>decoded</code> would then contain <code>"䅁䅁"</code>.

As other have pointed out, changing the <code>%</code> to <code>\</code> would work, but <code>UrlDecode</code> is the preferred method, since that ensures that other escaped symbols are translated correctly as well.

blocks|key|3039832|text|将%25符号改为反斜杠，您就得到了一个C#字符串文字。C#将\uxxxx视为转义序列，其中xxxx是4位数。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3039833|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Change the % signs to backslashes and you have a C# string literal. C# treats \uxxxx as an escape sequence, with xxxx being 4 digits.

blocks|key|5155870|text|在基本字符串用法中，您可以使用Unicode:+var+someLine=“\u4141”初始化字符串变量；如果可能-将所有"%25u“替换为"\u”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5155871|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In basic string usage you can initiate string variable in Unicode:
var someLine="\u4141";
If it is possible - replace all "%u" with "\u".

You need <a href="http://msdn.microsoft.com/en-us/library/system.web.httputility.urldecode.aspx" rel="nofollow noreferrer"><code>HttpUtility.UrlDecode</code></a>. You shouldn't really be using <code>escape/unescape</code> in most cases nowadays, you should be using things like <code>encodeURI/decodeURI/encodeURIComponent</code>.

I am trying to analyse some <code>JavaScript</code>, and one line is 

<pre><code>var x = unescape("%u4141%u4141 ......"); 
</code></pre>

with lots of characters in form <code>%uxxxx</code>.

I want to rewrite the <code>JavaScript</code> in <code>c#</code> but can't figure out the proper function to decode a string of characters like this. I've tried 

<pre><code>HttpUtility.HTMLDecode("%u4141%u4141");
</code></pre>

but this did not change these characters at all. 

How can I accomplish this in c#?

what is the c# equivalent to javascript's unescape()?
