Visual Studio Code: 2020年5月(版本1.46) Shift +向上/向下箭头:复制代码行

在Visual Studio 2022中

Ctrl + E, V

在Visual Studio 2019中

Ctrl + D

在Visual Studio 2017 (v15.6及以后版本)中

Ctrl + D

在Visual Studio 2017 (pre v15.6)

(编辑)这个功能现在是内置在VS2017: Ctrl + E, V复制一行，如果没有选择，或重复选择。你可以将它分配给不同的键组合，或者在菜单中找到它:

有关更多信息，请参阅此参考资料。

Pre VS2017，内置方法使用剪贴板

正如@cand提到的，你可以按Ctrl + C;Ctrl + V。

如果没有选择，Ctrl + C将复制该行。

宏观解决方案(VS2017前期)

如果你想实现一个更完整的解决方案，也许是创建一个更简单的键盘快捷键，或者你不想影响剪贴板，请参阅以下指南:

Visual Basic: Imports System Imports EnvDTE Imports EnvDTE80 Imports System.Diagnostics Public Module DuplicateLastLineModule Sub DuplicateLine() Dim line As String DTE.ActiveDocument.Selection.StartOfLine(0) DTE.ActiveDocument.Selection.EndOfLine(True) line = DTE.ActiveDocument.Selection.Text DTE.ActiveDocument.Selection.EndOfLine() DTE.ActiveDocument.Selection.NewLine() DTE.ActiveDocument.Selection.StartOfLine(0) DTE.ActiveDocument.Selection.Text = line End Sub End Module To create the macro, just go to the macro explorer ("Tools->Macros->Macro Explorer" or Alt+F8) and copy paste the code in a new module. Now just assign a keyboard shortcut to it: go to Tools->Options... under Environment, click Keyboard in the "Show Commands Containing" textbox, enter "duplicate" (this according to the name you gave the module.) you should now see the macro in the list below choose "Text Editor" from the "Use new shortcut in" list set focus in the "Press shortcut keys" textbox and hit the combination on the keyboard you wish to use for it (Ctrl+Shift+D in my case) hit the "Assign" button you should now see the shortcut in the "Shortcuts for selected command" textbox hit the OK button And that's it. Enjoy!

在VS2019和VS2017中，你可以选择工具->选项->键盘，你可以在方案下拉Resharper (Visual Studio)选项中选择，你会得到一个映射，如果你使用Resharper，在这种情况下，Ctrl + D将完成复制线条的技巧。无论如何，根据文档，这应该在Visual Studio 2017 Version 15.8或更高版本中推出

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

为什么要用这么长的方法来完成这么简单的事情?它需要不到一分钟的时间从微软下载和安装扩展。该页面说它将默认绑定到ALT+D，但对我来说，它在Visual Studio Community 2015中自动绑定到CTRL+D，没有任何更改。

这里是从Microsoft.com下载扩展的链接。
