Open Project

To open a project, use the OpenProject method of the IWorkspace object. For UI interaction, you can display a dialog by using the ShowOpenFileDialog method of the ICommonUI object.

public void OpenProject(ICommandContext c, ICommandParams p) 
{ 
//Select a project file 
var filePath = c.App.Window.UI.ShowOpenFileDialog("Please select a project file.", "Project file|*.iproj;*.nproj"); 
if ( filePath == null ) return "Cancelled."; 

//Open a project file 
c.App.Workspace.OpenProject(filePath); 
}
