Javascript 中的decodeURI和 asp.net HttpUtility.UrlEncode之间的乱码解决方案

client端不动：

server:

  public class HttpTools

        return Encoding.ASCII.GetString(data);

    }
    internal static bool IsSafe(char ch)
    {
        if ((((ch >= 'a') && (ch <= 'z')) || ((ch >= 'A') && (ch <= 'Z'))) || ((ch >= '0') && (ch <= '9')))

                return true;
        }

    }

    internal static char IntToHex(int n)

        int num4 = 0;

----------------------------------

encodeURI() 方法：把URI字符串采用UTF-8编码格式转化成escape格式的字符串。不会被此方法编码的字符：! @ # $& * ( ) = : / ; ? + '

英文解释：MSDN JScript Reference: The encodeURI method returns an encoded URI. If you pass the result to decodeURI, the original string is returned. The encodeURI method does not encode the following characters: ":", "/", ";", and "?". Use encodeURIComponent to encode these characters. Edge Core Javascript Guide: Encodes a Uniform Resource Identifier (URI) by replacing each instance of certain characters by one, two, or three escape sequences representing the UTF- 8 encoding of the character
