It depends a little on what you are trying to do and which version of Rhino you are running.

If you are running Rhino 4 and using the Rhino_DotNet SDK, then you need to have your command class derive from MRhinoScriptCommand and call RhinoApp().RunScript(@"-_Open C:\path_to_model.3dm")

If you are running Rhino 5 and using the RhinoCommon SDK (recommended), then you should call RunScript in a fashion that Brian suggested above. You also need to mark your command class with the the Rhino.Commands.Style attribute of ScriptRunner

ex.

using Rhino.Commands;

[CommandStyle(ScriptRunner)]
class MyCommand : Rhino.Commands.Command
{
  public override string EnglishName { get { return "MyCommand"; } }

  protected override Result RunCommand(RhinoDoc doc, RunMode mode)
  {
    RhinoApp.RunScript(@"-_Open C:\model.3dm");
  }
}

This will open the 3dm file and make it the active document.

On the other hand if you just want to read the 3dm file into memory and inspect the contents of it, I would recommend using the Rhino.FileIO.File3dm class in RhinoCommon. There is a static Read function on that class that you can use.

You can script the Open command from inside a plug-in using:

Rhino.RhinoApp.RunScript() to script the open command. For example:

Rhino.RhinoApp.RunScript(@"-_Open C:\model.3dm");
