How to Format a string to be a part of URL?

I need to remove all chars that cant be part of urls, like spaces ,<,> and etc.

I am getting the data from database.
For Example if the the retrieved data is: Product #number 123!

the new string should be: Product-number-123

Should I use regex? is there a regex pattern for that? Thanks

An easy regex to do this is:

string cleaned = Regex.Replace(url, @"[^a-zA-Z0-9]+","-");

To just perform the replacement of special characters like "<" you can use Server.UrlEncode(string s). And you can do the opposite with Server.UrlDecode(string s).

Here is a an example on how to generate an url-friendly string from a "normal" string:

public static string GenerateSlug(string phrase)
{
    string str = phrase.ToLower();

    str = Regex.Replace(str, @"[^a-z0-9\s-]", ""); // invalid chars       
    str = Regex.Replace(str, @"\s+", " ").Trim(); // convert multiple spaces into one space
    str = str.Substring(0, str.Length <= 45 ? str.Length : 45).Trim(); // cut and trim it
    str = Regex.Replace(str, @"\s", "-"); // hyphens

    return str;
}

You may want to remove the trim-part if you are sure that you always want the full string.
