If you want to open the editor associated with a file, then just do:

 System.Diagnostics.Process.Start(path);

Where path is the FQN of the .pas file.

Basically, Windows will look for a program that is registered to view/edit the type (extension) of file when its not an executable. It will then create a new process passing the file name to the viewer/editor. See http://support.microsoft.com/kb/307859 for more info.

OR if by open, you mean making your WPF application the default program associated with .pas files. Then you need to make a few registry changes. This SO question provides the details.

OR if by open, you mean reading the file, then try System.IO.File.ReadAllLines or System.IO.File.ReadAllText. More info at File method.

  • By open I mean "open the editor associated" , so it was the first one ,thanks for your help – Manal Apr 28 '14 at 23:38
  • there is no `File.ReadAllTextLines` - there's `File.ReadAllText` and `File.ReadAllLines` though – Andrew Apr 29 '14 at 05:47

string[] lines = File.ReadAllLines("C:\input.pas");

For more information about File class, have a look at the resource here:

May be below code would help 

 using System.IO;

    FileStream fileStream = new FileStream(@"C:\input.pas", FileMode.Open);

  • It doesn't work, but when try this "System.Diagnostics.Process.Start(path);" I get what I want – Manal Apr 28 '14 at 23:45
