How do I decode a URL parameter using C#?

C#asp.netUrlUrldecode

C# Problem Overview

How can I decode an encoded URL parameter using C#?

For example, take this URL:

my.aspx?val=%2Fxyz2F

C# Solutions

Solution 1 - C#

string decodedUrl = Uri.UnescapeDataString(url)

or

string decodedUrl = HttpUtility.UrlDecode(url)

Url is not fully decoded with one call. To fully decode you can call one of this methods in a loop:

private static string DecodeUrlString(string url) {
    string newUrl;
    while ((newUrl = Uri.UnescapeDataString(url)) != url)
        url = newUrl;
    return newUrl;
}

Solution 2 - C#

Server.UrlDecode(xxxxxxxx)

Solution 3 - C#

Have you tried HttpServerUtility.UrlDecode or HttpUtility.UrlDecode?

Solution 4 - C#

Try:

var myUrl = "my.aspx?val=%2Fxyz2F";
var decodeUrl = System.Uri.UnescapeDataString(myUrl);

Solution 5 - C#

Try this:

string decodedUrl = HttpUtility.UrlDecode("my.aspx?val=%2Fxyz2F");
