How to open file programmatically using EnvDTE in C#.

Answer 1

You can try the following snippet directly in the Visual Studio Console:

$DTE.ItemOperations.OpenFile("c:\derp.txt",$DTE.Constants.vsViewKindTextView)

It should open the file as long as it exists...

Answer 2

Assuming you have a hook to the correct DTE instance...

DTE.ExecuteCommand("File.OpenFile", "c:\\derp.txt");
