Decode escaped Url without using HttpUtility.UrlDecode

Question

Is there any function that converts an escaped Url string to its unescaped form? System.Web.HttpUtility.UrlDecode() can do that job but I don\'t want to add a r

Answer 1

Just a little understanding of why it's different. One converts to uppercase and one converts to lowercase. So the decode is specific to the type of encode.

System.Net.WebUtility (Internal) + 65:

private static char IntToHex(int n)
{
    if (n <= 9)
        return (char) (n + 48);
    else
        return (char) (n - 10 + 65);
}

System.Web.Util.HttpEncoderUtility (Internal) - + 97

public static char IntToHex(int n)
{
    if (n <= 9)
        return (char) (n + 48);
    else
        return (char) (n - 10 + 97);
}

Example:

var test1 = WebUtility.UrlEncode("http://www.test.com/?param1=22¶m2=there@is

Response:

test1 -> http%3A%2F%2Fwww.test.com%2F%3Fparam1%3D22%26param2%3Dthere%40is%3Ca+space
test2 -> http%3a%2f%2fwww.test.com%2f%3fparam1%3d22%26param2%3dthere%40is%3ca+space
