在Visual Studio 2010中,有没有一种方法可以轻松地注释掉CSS中的行?

不幸的是,用于注释和取消注释的常规命令( Ctrl键 + K + C 和 Ctrl键 + K + U )不适用于CSS。相反,您需要记录或编写执行此操作的宏,并将其附加到自己的快捷方式。

要对所选文本进行注释(注意,这是快速且脏的,因此将其作为单个块进行注释):

Sub CssComment()
    DTE.ActiveDocument.Selection.Text = "/*" + DTE.ActiveDocument.Selection.Text + "*/"
End Sub

更新
下面这个新的命令更像是常规的注释命令和逐行的注释。这意味着您不必在手前选择文本。这也将所有更改作为一个可撤消的操作进行,并检查文件扩展名,以便您可以将其分配给常规快捷方式,并且它将对所有文件都有效。

Sub CommentCss()
    Dim ts1 As TextSelection = CType(DTE.ActiveDocument.Selection(), EnvDTE.TextSelection)

    Dim fileName = DTE.ActiveDocument.FullName

    ' We should default to regular commenting if we're not editing CSS.
    ' This allows this macro to be attached to the Ctrl+K+C shortcut
    ' without breaking existing file format commenting.
    If Not fileName.EndsWith(".css") Then
        DTE.ExecuteCommand("Edit.CommentSelection")
        Return
    End If

    Dim weOpenedUndo As Boolean = False
    If Not DTE.UndoContext.IsOpen Then
        DTE.UndoContext.Open("CommentCSS")
        weOpenedUndo = True
    End If

    ts1.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstColumn, True)
    Dim ep1 As EditPoint2 = ts1.TopPoint.CreateEditPoint()
    Dim ep2 As EditPoint2 = ts1.BottomPoint.CreateEditPoint()

    While ep1.Line <= ep2.Line
        Dim text As String = ep1.GetLines(ep1.Line, ep1.Line + 1)
        text = text.Trim()

        If Not text.StartsWith("/*") Or Not text.EndsWith("*/") Then
            ep1.StartOfLine()
            ep1.Insert("/*")
            ep1.EndOfLine()
            ep1.Insert("*/")
        End If
        Dim lineBeforeDown As Integer = ep1.Line
        ep1.LineDown()

        If ep1.Line = lineBeforeDown Then
            Exit While
        End If
    End While

    ts1.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstColumn, True)

    If weOpenedUndo Then
        DTE.UndoContext.Close()
    End If
End Sub

更新以取消注释
此宏执行反向任务。同样,它的实现是为了在需要时,通过检查文件扩展名并遵从标准,它可以为所有文档工作。 Edit.UncommentSelection 非css文件的命令。

Sub UncommentCss()
    Dim ts1 As TextSelection = CType(DTE.ActiveDocument.Selection(), EnvDTE.TextSelection)
    Dim ep1 As EditPoint2 = ts1.TopPoint.CreateEditPoint()
    Dim ep2 As EditPoint2 = ts1.BottomPoint.CreateEditPoint()

    Dim fileName = DTE.ActiveDocument.FullName

    ' We should default to regular commenting if we're not editing CSS.
    ' This allows this macro to be attached to the Ctrl+K+C shortcut
    ' without breaking existing file format commenting.
    If Not fileName.EndsWith(".css") Then
        DTE.ExecuteCommand("Edit.UncommentSelection")
        Return
    End If

    Dim weOpenedUndo As Boolean = False
    If Not DTE.UndoContext.IsOpen Then
        DTE.UndoContext.Open("UncommentCSS")
        weOpenedUndo = True
    End If

    While ep1.Line <= ep2.Line
        ep1.StartOfLine()

        Dim text As String = ep1.GetLines(ep1.Line, ep1.Line + 1)
        text = text.Trim()

        If text.StartsWith("/*") And text.EndsWith("*/") Then
            Dim epEndOfLine As EditPoint2 = ep1.CreateEditPoint()
            epEndOfLine.EndOfLine()
            text = text.Substring(2, text.Length - 4)
            ep1.ReplaceText(epEndOfLine, text, vsEPReplaceTextOptions.vsEPReplaceTextKeepMarkers Or vsEPReplaceTextOptions.vsEPReplaceTextAutoformat)
        End If

        Dim lineBeforeDown As Integer = ep1.Line
        ep1.LineDown()

        If ep1.Line = lineBeforeDown Then
            Exit While
        End If
    End While

    ts1.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstColumn, True)

    If weOpenedUndo Then
        DTE.UndoContext.Close()
    End If
End Sub

按照 dirq's answer ,有一个扩展名, Web Essentials 它提供CSS注释和取消注释。我建议在上面的宏上使用它,因为除了CSS注释快捷方式之外,它还提供了其他很好的支持。

有一个扩展比宏Web Essentials工作得更好。过来看。 http://visualstudiogallery.msdn.microsoft.com/6ed4c78f-a23e-49ad-b5fd-369af0c2107f
