C#中带有特殊字符的查询字符串问题 [英] Querystring Issue on C# with special characters

问题描述

我遇到了一个非常奇怪的问题，在我的querystirng中，"++"作为文本的一部分.但是，当我将查询搅拌值分配给字符串++时，它将变成两个空格.我该如何确切地获取作为查询字符串传递的内容?

I came across a very weird issue where in my querystirng had "++" as part of the text. but when i assign the query stirng value to a string ++ will become two spaces. How do i get exactly what is being passed as querystring?

我观察到querystirng集合具有"++"，但是当我执行Request.QueryString ["search"].ToString()"++"时，我在即时窗口中进行了检查.

I observed that the querystirng collection had "++" but when I do Request.QueryString["search"].ToString() "++" gone, I checked in Immediate window.

我使用C#2.0

URL:/default.aspx?search=test ++

URL: /default.aspx?search=test++

string t = Request.QueryString["search"].ToString();

推荐答案

查询字符串中的加号会转换为空格.如果要使用实际的加号而不是空格，请改用％2B .

A plus sign in a query string translates to a space. If you want an actual plus sign rather than a space, use %2B instead.

/default.aspx?search=test%2B%2B

如果您使用代码执行此操作，则应使用 UrlEncode 对查询字符串的这一部分进行编码.

If you're doing this in code, then you should be using UrlEncode to encode this portion of the query string.
