Answer 1

For visual studio 2010, try using these commands for quick line duplication (uses clipboard):

• Click on the line you want to copy. Ctrl + C will copy that line.

• Then press Ctrl + Shift + Enter to insert a blank below insertion point

  (Alternatively use Ctrl + Enter to insert a blank line above the insertion point.)

• Then simply use Ctrl + V to paste the line.

Answer 2

In Visual Studio 2019

Ctrl + D

In Visual Studio 2017 (v15.6 and after)

Ctrl + D

In Visual Studio 2017 (pre v15.6)

(edit) This feature is now built-in in VS2017: Ctrl + E, V duplicates a line if nothing is selected, or duplicates selection. You can assign it to a different key combination, or find it in the menu:

See this reference for more information.

Pre VS2017, built-in method using clipboard

As @cand mentioned, you can just do Ctrl + C ; Ctrl + V.

Ctrl + C will copy the line if nothing is selected.

Macro solution (pre VS2017)

If you'd like to implement a more complete solution, perhaps to create a simpler keyboard shortcut or you don't want to effect the clipboard, see this guide:

Duplicate line command for Visual Studio

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:

1. go to Tools->Options...
2. under Environment, click Keyboard
3. in the "Show Commands Containing" textbox, enter "duplicate" (this according to the name you gave the module.)
4. you should now see the macro in the list below
5. choose "Text Editor" from the "Use new shortcut in" list
6. set focus in the "Press shortcut keys" textbox and hit the combination on the keyboard you whish to use for it (Ctrl+Shift+D in my case)
7. hit the "Assign" button
8. you should now see the shortcut in the "Shortcuts for selected command" textbox
9. hit the OK button

And that's it. Enjoy!

My story: started working in a new company, never used Visual Studio before. One of the first things - how to duplicate line. After setting up macro ReSharper told me: would you like to substitute my shortcut which was: "duplicate text" :)

Answer 4

Just put your mouse on the line to copy and do CTRL+C ,afterwards CTRL+V on the same line. Works like magic :-)

Answer 5

In visual studio 2008 you can use CTRL + C + V

Answer 6

The command you want is Edit.Duplicate. It is mapped to CtrlE, CtrlV. This will not overwrite your clipboard.
