I am using silverlight / ASP .NET and C#. What if I want to do this from silverlight for instance,

// I have left out the quotes to show you literally what the characters
// are that I want to use
string password = vtakyoj#"5
string encodedPassword = HttpUtility.UrlEncode(encryptedPassword, Encoding.UTF8);
// encoded password now = vtakyoj%23%225

URI uri = new URI("http://www.url.com/page.aspx@password=vtakyoj%23%225");

HttpPage.Window.Navigate(uri);

If I debug and look at the value of uri it shows up as this (we are still inside the silverlight app),

http://www.url.com?password=vtakyoj%23"5

So the %22 has become a quote for some reason.

If I then debug inside the page.aspx code (which of course is ASP .NET) the value of Request["pasword"] is actually this,

vtakyoj#"5

Which is the original value. How does that work? I would have thought that I would have to go,

HttpUtility.UrlDecode(Request["pswd"], Encoding.UTF8)

To get the original value.

Hope this makes sense?

Thanks.
