EncodeURIComponent () garbled on the asp.net page

Today, I encountered a very annoying problem. After the Javascript encodeURIComponent () method encrypted string get is submitted, garbled characters are always obtained during asp.net page decoding.

Through simple analysis, the UrlEnCode string generated by my Javascript is in UTF-8 format, while the RequestEncoding = "gb2312" on the asp.net page of the receiver appears here.
Finally, this method is used to solve the problem:

System. Collections. Specialized. NameValueCollection gb2312 = HttpUtility. ParseQueryString (Request. Url. Query, System. Text. Encoding. GetEncoding ("UTF-8 "));
_ Keywords = gb2312 ["Keywords"];

The advantage of this method is that you can ignore the encoding problem of the sending page and getting page. You only need to know the encoding format of the sender!
