How to combine URIs

Question

I have two Uri objects passed into some code, one is a directory and the other is a filename (or a relative path)

var a = new Uri(\"file:///C:/Some/Dirs\");
         


        

Answer 1

add a slash end of your first uri, URI will ignore more than one slash (/)

var a = new Uri("file:///C:/Some/Dirs/");

EDIT:

var a = new Uri("file:///C:/Some/Dirs");
var b = new Uri("some.file",  UriKind.Relative);
var c = new Uri(Path.Combine(a.ToString(), b.ToString()));
MessageBox.Show(c.AbsoluteUri);
