这是什么编码？

Question

What kind of encoding do you use to encode http:// as http%253A%252F%252F

HttpUtility.UrlEncode gives http%3a%2f%2f

Answer 1

What you're looking at is text that has been passed through UrlEncode twice .

The second time changes the % symbols to %25 .

It's unusual to pass an entire URL through UrlEncode anyway, unless you are passing it as a parameter in another URL (for redirection, for instance).

Answer 2

看起来UrlEncode被调用了两次，将文字%编码为%25 （顺便说一句，这是正确的结果）。
