Format Multiline code to single line in Visual Studio

问题

Is there a keyboard shortcut or fast way to change the below code to a single line in Visual Studio 2013? I also have Resharper installed.

Multi

new XElement("Option",
            new XAttribute("Name", "FileDelete"),
            "1"
        ),

Single

new XElement("Option", new XAttribute("Name", "FileDelete"),"1" ),

回答1:

Just select all the text

and press (control + j)

and it will become 1 line of code

I setup find/replace for quick use with a regex expression like so:

(note: I use VS 2015, so your hotkeys may be different)

1. Use Ctrl+H to open quick find replace.
2. Make sure the "Use Regular Expressions" button is active/toggled-on, and that you are set to search in "Selection" (Not "Document" or "Entire Solution" or whatever)
3. Type
   \s+
   and a space ()
   in the "find" and "replace with" boxes respectively.
4. Press Esc key to exit quick find/replace.
5. Now, as long as you don't change anything, you can select any text you want to make single line, and use the following hotkey sequence to quickly format it:
   1. Ctrl+H (Open quick find/replace)
   2. Alt+A (Replace any occurrence of 1 or more White Spc chars with a single space.)
   3. Enter (Close the popup window that says "X Occurrences Found")
   4. Esc (Exit quick find/replace and return to your code)

I use this all the time after visual studio does things like implementing interfaces to turn stuff like

public SomeType SomeProperty {
    get {
        throw new NotImplementedException();
    }
    set {
        throw new NotImplementedException();
    }
}

into stuff like

public SomeType SomeProperty { get { return someField; } set { /*Some Simple Set Code*/; } }

To make it with ReSharper, you should uncheck the option "Keep existing line breaks" in ReSharper/Options/Code Editing/C#/Formatting style/Line Breaks and Wrapping.

Or just add this line into your .dotSettings

<s:Boolean x:Key="/Default/CodeStyle/CodeFormatting/CSharpFormat/KEEP_USER_LINEBREAKS/@EntryValue">False</s:Boolean>

Then you could format your code using Code Cleanup Tool (default shortcut is Ctrl+Alt+F) or just by typing semicolons or braces.

You can change your VS settings to automatically format code in whatever way you want, then select and retype any line/block-ending character (';' or '}') after the text you want formatted and VS will format it for you.

You can accomplish this using CodeMaid. The default keybinding is F3, but the command is called CodeMaid.JoinLines if you want to change it
