Visual Studio, Collapse/Extends Regions ONLY shortcut

问题

Is there any shortcut to collapse/expand the regions ONLY? Meaning, if I have a region with 5 methods in it, and I hit collapse, the region will collapse, and when I will hit expand, the region will expand and I will see all 5 methods with the same state as it was before (collapsed/expanded).

Currently the shortcuts I found collapse ALL, or expand ALL, or substitutes the "All" word for the "Current" word.

I'm looking for a shortcut that will collapse only regions, and will not do anything to the other blocks inside a region. Same thing with expanding.

If there is no such thing, maybe someone found some visual extension to do it?

You can use the following macros to expand/collapse the regions while leaving the expand/collapse state of individual methods as they were.

I found the macro here. Note that I had to comment out the call to objSelection.EndOfDocument() from the CollapseAllRegions method for it to work properly (using Visual Studio 2010)

Imports EnvDTE
Imports System.Diagnostics
' Macros for improving keyboard support for "#region ... #endregion"
Public Module RegionTools
    ' Expands all regions in the current document
    Sub ExpandAllRegions()

        Dim objSelection As TextSelection ' Our selection object

        DTE.SuppressUI = True ' Disable UI while we do this
        objSelection = DTE.ActiveDocument.Selection() ' Hook up to the ActiveDocument's selection
        objSelection.StartOfDocument() ' Shoot to the start of the document

        ' Loop through the document finding all instances of #region. This action has the side benefit
        ' of actually zooming us to the text in question when it is found and ALSO expanding it since it
        ' is an outline.
        Do While objSelection.FindText("#region", vsFindOptions.vsFindOptionsMatchInHiddenText)
            ' This next command would be what we would normally do *IF* the find operation didn't do it for us.
            'DTE.ExecuteCommand("Edit.ToggleOutliningExpansion")
        Loop
        objSelection.StartOfDocument() ' Shoot us back to the start of the document
        DTE.SuppressUI = False ' Reenable the UI

        objSelection = Nothing ' Release our object

    End Sub

    ' Collapses all regions in the current document
    Sub CollapseAllRegions()

        Dim objSelection As TextSelection ' Our selection object

        ExpandAllRegions() ' Force the expansion of all regions

        DTE.SuppressUI = True ' Disable UI while we do this
        objSelection = DTE.ActiveDocument.Selection() ' Hook up to the ActiveDocument's selection
        objSelection.EndOfDocument() ' Shoot to the end of the document

        ' Find the first occurence of #region from the end of the document to the start of the document. Note:
        ' Note: Once a #region is "collapsed" .FindText only sees it's "textual descriptor" unless
        ' vsFindOptions.vsFindOptionsMatchInHiddenText is specified. So when a #region "My Class" is collapsed,
        ' .FindText would subsequently see the text 'My Class' instead of '#region "My Class"' for the subsequent
        ' passes and skip any regions already collapsed.
        Do While (objSelection.FindText("#region", vsFindOptions.vsFindOptionsBackwards))
            DTE.ExecuteCommand("Edit.ToggleOutliningExpansion") ' Collapse this #region
            'objSelection.EndOfDocument() ' Shoot back to the end of the document for
            ' another pass.
        Loop
        objSelection.StartOfDocument() ' All done, head back to the start of the doc
        DTE.SuppressUI = False ' Reenable the UI

        objSelection = Nothing ' Release our object

    End Sub
End Module

I've written a free Visual Studio extension "Menees VS Tools" that provides commands for "Collapse All Regions" and "Expand All Regions". It's available for VS versions from 2003 to 2013. The VS 2013 and VS 2012 versions are available in the Visual Studio Gallery.
