One of the features I worked on for the Visual Studio 2008 release was the new "Organize Usings" feature. This feature allows you to:
We've received a great response from customers on the usefulness of this feature but one of the questions that I've received quite often is - "is there a way to make the feature work on an entire project or solution"? The current answer to this is no. Given the number of times I've heard the request though, I thought it would be worth posting a workaround that uses macros.
So here's what you need to do - it's really quite simple:
Step 1: Create a new macro in Visual Studio through the Tools | Macros menu.
Step 2: Paste the code below into the Module and save it
Note that the code below is courtesy of Kevin Pilch-Bisson (http://blogs.msdn.com/kevinpilchbisson/archive/2004/05/17/133371.aspx) and Chris Eargle (http://www.chriseargle.com/post/Format-Solution.aspx), who have posted macros that allow you to format across an entire solution. I'm simply re-applying their approach to invoke the RemoveAndSort command rather than the FormatDocument command. Note that I haven't tested this macro extensively so please use at your own risk.
Public Module Module1
Dim sol As Solution = DTE.Solution
For i As Integer = 1 To sol.Projects.Count
Private Sub OrganizeProject(ByVal proj As Project)
For i As Integer = 1 To proj.ProjectItems.Count
Private Sub OrganizeProjectItem(ByVal projectItem As ProjectItem)
Dim fileIsOpen As Boolean = False
If projectItem.Kind = Constants.vsProjectItemKindPhysicalFile Then
'If this is a c# file
If projectItem.Name.LastIndexOf(".cs") = projectItem.Name.Length - 3 Then
'Set flag to true if file is already open
fileIsOpen = projectItem.IsOpen
Dim window As Window = projectItem.Open(Constants.vsViewKindCode)
'Only close the file if it was not already open
If Not fileIsOpen Then
'Be sure to apply RemoveAndSort on all of the ProjectItems.
If Not projectItem.ProjectItems Is Nothing Then
For i As Integer = 1 To projectItem.ProjectItems.Count
'Apply RemoveAndSort on a SubProject if it exists.
If Not projectItem.SubProject Is Nothing Then
Step 3: Run the macro on any solution that you'd like and there you have it! Enjoy :)
