在visual studio 2008中，可以使用CTRL + c++ V

Ctrl + D为我工作在VS2012与Resharper。这是Resharper的热键。

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”:)

在Linux Mint上，你可以这样做; Ctrl + Alt + Shift + 2 =>复制 Ctrl + Alt + Shift + 8 =>复制下来

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

Ctrl + D是VS 2017 v15.6中引入的一个新快捷键，它的作用似乎和Ctrl + E, V完全一样

Ctrl + D将复制光标所在的行，并将其插入到焦点行的正下方。如果希望复制一组特定的代码，只需在调用duplicate code命令之前选择要复制的代码部分。

它不会影响你的剪贴板
