System. Web. httputility. urlencode: encode and convert Chinese characters and URLs

Today, I am working on a small program to find that the encoding produced by the C # system. Web. httputility. urlencode function is different from that we normally use, for example:

The encoding produced by using system. Web. httputility. urlencode is as follows:

Nanjing: % E5 % 8d % 97% E4 % Ba % AC

The expected result is % c4 % CF % be % A9.

After comparison, it is found that the two are considered to be one Chinese character with three bytes, while the latter is two bytes. This suddenly realizes that if system is used directly in C. web. httputility. urlencode ("Nanjing") then the program uses UTF-8 encoding to process Chinese characters by default.

 

Solution:

System. Web. httputility. urlencode ("Nanjing", encoding. getencoding ("gb2312 "))

Add a parameter!
