Remove file:// prefix c#

Question

I have the follow:

string file = string.Concat(
                 System.IO.Path.GetDirectoryName(
                    System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase
                 ), 
              "bla.xml");

Now file is:

file:\C:\test\Debugbla.xml

How can i remove the "file:\" prefix?

Thanks

Answer 1

Uri class is the way to manipulate Uri. While string.Replace is an option it is better to use tools explicitly designed for particular case which also take care of handling escaping rules where necessary.

string file = string.Concat(System.IO.Path.GetDirectoryName(
     System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase), "bla.xml");

file = new Uri(file).AbsolutePath; 

UPDATE:

More robust implementation eliminating string.Concat to handle other cases including fragments in the codebase url.

var codebase = new Uri(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);

var file = new Uri(codebase, "bla.xml").AbsolutePath;

Use the Assembly.Location property instead, which returns a normal filepath.

Also, use Path.Join().
