C＃是否与JavaScript的encodeURIComponent（）相当？ [英] Does C# have an equivalent to JavaScript's encodeURIComponent()?

问题描述

在JavaScript中：

  encodeURIComponent（©√）==％C2％A9％E2％88％9A 
  

是否有C＃应用程序的等效项？对于转义HTML字符，我使用：

  txtOut.Text = Regex.Replace（txtIn.Text，@[\\\€- \\\￿]，
m => @&＃+（（int）m.Value [0]）ToString（）+;）; 
  

但我不知道如何将匹配转换为JS使用的正确的十六进制格式。例如这个代码：

  txtOut.Text = Regex.Replace（txtIn.Text，@[\\\€-\ uFFFF]，
m => @％+ String.Format（{0：x}，（（int）m.Value [0]）））; 
  

返回％a9％221a ©√而不是％C2％A9％E2％88％9A。看起来我需要将字符串分割成字节或某些东西。

编辑：这是一个Windows应用程序，唯一可用的项目 ASP.NETHostingPermissionLevel 。

解决方案

Uri.EscapeDataString HttpUtility.UrlEncode 是逃避一个意图成为URL一部分的字符串的正确方法。

c code code code code > HttpUtility.UrlEncode（Stack Overflow） - > Stack + Overflow

Uri.EscapeUriString（Stack Overflow） - > Stack％20Overflow / p>

Uri.EscapeDataString（Stack + Overflow） - >还编码+到％2b ----> 堆栈％20％2B％20％20Overflow

O当用作URL的实际部分（与查询字符串参数之一的值相反）

时，nly 后面的 last是正确的

In JavaScript:

encodeURIComponent("©√") == "%C2%A9%E2%88%9A"

Is there an equivalent for C# applications? For escaping HTML characters I used:

txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]",
    m => @"&#" + ((int)m.Value[0]).ToString() + ";");

But I'm not sure how to convert the match to the correct hexadecimal format that JS uses. For example this code:

txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]",
    m => @"%" + String.Format("{0:x}", ((int)m.Value[0])));

Returns "%a9%221a" for "©√" instead of "%C2%A9%E2%88%9A". It looks like I need to split the string up into bytes or something.

Edit: This is for a windows app, the only items available in System.Web are: AspNetHostingPermission, AspNetHostingPermissionAttribute, and AspNetHostingPermissionLevel.

解决方案

Uri.EscapeDataString or HttpUtility.UrlEncode is the correct way to escape a string meant to be part of a URL.

Take for example the string "Stack Overflow":

• HttpUtility.UrlEncode("Stack Overflow") --> "Stack+Overflow"

• Uri.EscapeUriString("Stack Overflow") --> "Stack%20Overflow"

• Uri.EscapeDataString("Stack + Overflow") --> Also encodes "+" to "%2b" ---->Stack%20%2B%20%20Overflow

Only the latter last is correct when used as an actual part of the URL (as opposed to the value of one of the query string parameters)
