How do I decode a URL parameter using C#?

Question

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

For example, take this URL:

my.aspx?val=%2Fxyz2F

Answer 1

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;
}

Answer 2

Server.UrlDecode(xxxxxxxx)

Answer 3

您是否尝试过HttpServerUtility.UrlDecode或HttpUtility.UrlDecode ？

Answer 4

尝试这个：

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

Answer 5

Try:

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