Httputility. urlencode () About Space Encoding

E is converted into space, but the browser cannot understand that the "+" is space, so if the file name contains
The space is changed to "+" after the file is downloaded from the browser.

One solution is to manually Replace "+" with "% 20" after httputility's urlencode"(If the original

"+" Is converted to "% 2B"), for example:

1. // Encode and convert the URL, and then obtain the URL public static string geturl (string URL) {string urlcode = ""; urlcode = httputility. urlencode (URL, encoding. utf8); // + with a space urlcode = urlcode. replace ("+", "% 20"); // The original is + restored urlcode = urlcode. replace ("% 2B", "+"); Return urlcode ;}
