Programmatically open a file in Visual Studio (2010)

I'开发者_如何学Pythonm building a VS package, and I'm trying to send a command from the package to Visual Studio to open up a user selected file in a new tab (just like a user would do it by going to File -> Open...).

I remember seeing at some point how to do this. Can anybody refresh my memory?

I believe you want one of:

1. IVsUIShellOpenDocument.OpenStandardEditor
2. DTE.OpenFile
3. DTE.ItemOperations.OpenFile

In the end, I think they all boil down to the same behavior.

I like to use the DTE method ExecuteCommand("commandName") as you can test the command in the VS Command Window

In this case ExecuteCommand("File.OpenFile")

You can add parameters to the command in a second optional string parameter if you wish.

You can use this function: VsShellUtilities.OpenDocument

If you call it from VSPackage method it looks like:

VsShellUtilities.OpenDocument(this, fileName);

Namespace: Microsoft.VisualStudio.Shell

Assemblies: Microsoft.VisualStudio.Shell.15.0.dll, Microsoft.VisualStudio.Shell.14.0.dll

Also it has two overloads which return additional information for opened document.

NOTE: This function is available in VS 2015 and later.
