Does C have an equivalent to JavaScript s encodeURIComponent

Question

In JavaScript   encodeURIComponent    v        C2 A9 E2 88 9A    Is there an equivalent for C  applications  For escaping HTML characters I used   txtOut Text   Regex Replace txtIn Text      u0080- uFFFF        m   gt     amp        int m Value 0   ToString             But I m not sure how to convert the match to the correct hexadecimal format that JS uses  For example this code   txtOut Text   Regex Replace txtIn Text      u0080- uFFFF        m   gt         String Format   0 x      int m Value 0        Returns   a9 221a  for    v  instead of   C2 A9 E2 88 9A   It looks like I need to split the string up into bytes or something   Edit  This is for a windows app  the only items available in System Web are  AspNetHostingPermission  AspNetHostingPermissionAttribute  and AspNetHostingPermissionLevel

You can use the Server object in the System.Web namespace

Server.UrlEncode, Server.UrlDecode, Server.HtmlEncode, and Server.HtmlDecode.

Edit: poster added that this was a windows application and not a web one as one would believe. The items listed above would be available from the HttpUtility class inside System.Web which must be added as a reference to the project.

Try Server UrlEncode    or System Web HttpUtility UrlEncode   for instances when you don t have access to the Server object  You can also use System Uri EscapeUriString   to avoid adding a reference to the System Web assembly

Uri EscapeDataString or HttpUtility UrlEncode is the correct way to escape a string meant to be part of a URL   Take for example the string  Stack Overflow     HttpUtility UrlEncode  Stack Overflow   --   Stack Overflow  Uri EscapeUriString  Stack Overflow   --   Stack 20Overflow  Uri EscapeDataString  Stack    Overflow   --  Also encodes     to   2b  ---- Stack 20 2B 20 20Overflow   Only the last is correct when used as an actual part of the URL  as opposed to the value of one of the query string parameters
