Remove additional slashes from URL

Question

In ASP.Net it is posible to get same content from almost equal pages by URLs like localhost:9000/Index.aspx and localhost:9000//Index.aspx or even localhost:9000///Index.aspx

But it isn't looks good for me.

How can i remove this additional slashes before user go to some page and in what place?

If your url includes the http:\\ part, you're screwed with all of the current answers. Don't just replace, build the url with care. — daniloquio, Apr 04 '16 at 15:16

Use this :

url  = Regex.Replace(url  , @"/+", @"/");

it will support n times

What tool are you using in that screenshot? – Kellen Stuart Apr 29 '20 at 17:06
@KellenStuart, a bit late to the party, but that looks like LINQPad. – easuter Nov 15 '22 at 18:46

You need to specify a base Uri and a relative path to get the canonized behavior.

Uri baseUri = new Uri("http://www.contoso.com");
Uri myUri = new Uri(baseUri, "catalog/shownew.htm");
Console.WriteLine(myUri.ToString());

This solution is not that pretty but very easy

do
{
    url = url.Replace("//", "/");
}
while(url.Contains("//"));

This will work for many slashes in your url but the runtime is not that great.

This won't work if URL string contains something like this 'https://examplewebsite.com//some-page' it will remove '//' from 'https://' and URL wont work. – Rushabh Master Feb 18 '19 at 23:02

Remove them, for example:

 url = url.Replace("///", "/").Replace("//", "/");

Here is the code snippets for combining URL segments, with the ability of removing the duplicate slashes:

    public class PathUtils
    {

        public static string UrlCombine(params string[] components)
        {
            var isUnixPath = Path.DirectorySeparatorChar == '/';

            
            for (var i = 1; i < components.Length; i++)
            {
                if (Path.IsPathRooted(components[i])) components[i] = components[i].TrimStart('/', '\\');
            }

            var url = Path.Combine(components);

            if (!isUnixPath)
            {
                url = url.Replace(Path.DirectorySeparatorChar, '/');
            }
            return Regex.Replace(url, @"(?<!(http:|https:))//", @"/");
        }
    }
