How to get a certain part of current URL in silverlight?

I need a certain part of current URL.

Sa开发者_运维问答y for example the URL is: http://www.abc.com/123/product/234?productid=123

And I want to check if a certain string contains http://www.abc.com/123

Please don't give answers like "do string manipulation" and all. Is there a way to get this sort of URL?

The Uri class has some really helpful methods for Uri mangling - including Uri.TryCreate.

Specifically, the GetComponents method might help you.

Try this:

Application.Current.Host.Source.AbsoluteUri 

That will give the url to your .xap file. You will have to replace your .xap path and you have your application uri.

Application.Current.Host.Source.AbsoluteUri.Replace(@"ClientBin/MySilverlight.xap", "");

I opted for a completely generic solution:

    /// <summary>
    /// Get the site URL (one step up from ClientBin)
    /// </summary>
    public string HostWebSite
    {
        get
        {
            string host = App.Current.Host.Source.AbsoluteUri;
            int clientBin = host.IndexOf("ClientBin", 0);
            if (clientBin == -1)
                return "Could not find \"ClientBin\" in " + host;

            return host.Substring(0, clientBin);
        }
    }

string myString = "http://www.abc.com/123/product/234?productid=123";
bool contains = myString.Contains("http://www.abc.com/123");

You can get the current uri using HtmlPage.Document.DocumentUri (this works in *.xaml.cs files)
