.NET UrlEn code - 小写问题， [英] .net UrlEncode - lowercase problem

问题描述

我工作的一个数据传输要求我在UrlEn codeD的形式发送数据的网关。但是，.NET的UrlEn code创建小写字母标记，它打破了转移（Java的创建大写）。

I'm working on a data transfer for a gateway which requires me to send data in UrlEncoded form. However, .net's UrlEncode creates lowercase tags, and it breaks the transfer (Java creates uppercase).

任何想法我怎么能强迫.NET做大写URL编码？

Any thoughts how can I force .net to do uppercase UrlEncoding?

UPDATE1：

.NET出来：

dltz7UK2pzzdCWJ6QOvWXyvnIJwihPdmAioZ%2fENVuAlDQGRNCp1F

VS Java的：

vs Java's:

dltz7UK2pzzdCWJ6QOvWXyvnIJwihPdmAioZ%2FENVuAlDQGRNCp1F

（这是一个base64d 3DES字符串，我需要保持它的情况下）。

(it is a base64d 3DES string, i need to maintain it's case).

推荐答案

我想你坚持什么C＃给你，并得到错误提示的另一端执行不力UrlDe code函数。

I think you're stuck with what C# gives you, and getting errors suggests a poorly implemented UrlDecode function on the other end.

随着中说，你应该只需要通过字符串循环和大写只有两个字符如下％符号。这将让您的base64数据完好无损，而按摩EN codeD字符转换成合适的格式为：

With that said, you should just need to loop through the string and uppercase only the two characters following a % sign. That'll keep your base64 data intact while massaging the encoded characters into the right format:

public static string UpperCaseUrlEncode(string s)
{
  char[] temp = HttpUtility.UrlEncode(s).ToCharArray();
  for (int i = 0; i < temp.Length - 2; i++)
  {
    if (temp[i] == '%')
    {
      temp[i + 1] = char.ToUpper(temp[i + 1]);
      temp[i + 2] = char.ToUpper(temp[i + 2]);
    }
  }
  return new string(temp);
}
