对于那些在2008年之后还在Visual Studio上查看这个问题的人，一个真正的编辑。副本已添加:

CTRL + E, V Ctrl + d (vs 2017 15.6+)

您需要的命令是Edit.Duplicate。它被映射到CtrlE, CtrlV。这不会覆盖你的剪贴板。

VS 2017的Ctrl + D或Ctrl + C;Ctrl + V 他们都为我工作。

如果你喜欢使用CTRL+ALT+UP或CTRL+UP+DOWN复制eclipse样式的行(或块)，下面我发布了用于此目的的宏:

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics

Public Module DuplicateLineModule
    Sub DuplicateLineDown()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.TopLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.EndOfLine()
        selection.Insert(vbNewLine & line)
    End Sub
    Sub DuplicateLineUp()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        lineNumber = selection.BottomLine
        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.Insert(vbNewLine & line)
        selection.MoveToDisplayColumn(lineNumber, 0)
    End Sub
End Module

在Visual Studio 2013中，可以使用Ctrl+C+V

我的故事:开始在一家新公司工作，以前从未使用过Visual Studio。第一件事之一，如何复制线条。设置宏后ReSharper告诉我:你想取代我的快捷方式是:“复制文本”:)
