适用于 Visual Studio .NET 的折叠全部宏

引言

Visual Studio .NET 具有一个很酷的功能，它可以自动将解决方案资源管理器与打开的文件同步。 然而，一个问题是，如果您有大量的项目，分支的数量很快就会失控——您会因为过多的分支而看不到树木，可以说。这是一个非常简单的宏，您可以用来折叠解决方案资源管理器中的所有项目节点。

宏代码

    Sub CollapseAll()

        ' Get the the Solution Explorer tree
        Dim UIHSolutionExplorer As UIHierarchy
        UIHSolutionExplorer = DTE.Windows.Item( _
            Constants.vsext_wk_SProjectWindow).Object()

        ' Check if there is any open solution
        If (UIHSolutionExplorer.UIHierarchyItems.Count = 0) Then
            ' MsgBox("Nothing to collapse. You must have an open solution.")
            Return
        End If

        ' Get the top node (the name of the solution)
        Dim UIHSolutionRootNode As UIHierarchyItem
        UIHSolutionRootNode = UIHSolutionExplorer.UIHierarchyItems.Item(1)

        ' Collapse each project node
        Dim UIHItem As UIHierarchyItem
        For Each UIHItem In UIHSolutionRootNode.UIHierarchyItems
            UIHItem.UIHierarchyItems.Expanded = False
        Next

        ' Select the solution node, or else when you click 
        ' on the solution window
        ' scrollbar, it will synchronize the open document 
        ' with the tree and pop
        ' out the corresponding node which is probably not what you want.
        UIHSolutionRootNode.Select(vsUISelectionType.vsUISelectionTypeSelect)

    End Sub
