Open a file with other extension using C#

Question

I have file with .xml extension. Using C# i have to open the file with another extension, like .exe for example. I can open the file with the 'Open With' option manually. Now I have to do the same using C#. How do I do that?

Wait. Are you trying to open a binary (.exe) file in Visual Studio? I dont think that will do you any good. I think you need to rephrase the question (I tried to clean it up a little but couldnt figure out what you mean). — Mizipzor, Jul 06 '10 at 08:56

I'm guessing your question is that you want to open a File using C# with any program you specify.

You'll have to launch the file as an argument of a process that can support the file type:

Process process = new Process();
process.StartInfo.FileName = "SomeApplication.exe"; // The app to "Open With..."
process.StartInfo.Arguments = "'C:\\YourFile.xml'"; // The file to open
process.Start();

@jonathon - Mind reading is a necessary skill for a programmer. How else are we meant to know what clients want? – djdd87 Jul 06 '10 at 09:09

string xmlname = "c:\\test.xml";    
string exename = System.IO.Path.ChangeExtension(xmlname, "exe");

I reread your question. I think you want to start the application with the Process.Start() method.

This is how I interpreted the requirement too. – Phil Gan Jul 06 '10 at 09:35

Visual Studio's default editor for other file extensions is set in Tools | Options | Text Editor | File Extensions.
