VS 宏/插件将字符串连接转换为 string.format 样式

Question

我有一个正在开发的项目，其中很多地方都使用了诸如“Hi”+variable+“，welcome to Project”之类的字符串操作（给出的示例非常小）。

要求之一是将其转换为 string.format 样式。

这是一项非常漫长且乏味的工作，我不想破坏早期的工作代码，因为在转换它时可能会发生任何人为错误。

我想知道我是否可以创建任何宏或 VS 命令来处理它。就像我们标记代码块并在重构选项中执行提取功能一样。

我觉得在这里发布代码有点长，但我在我的博客上发布了答案：

    Dim delimt As String = ", "
    Dim fmtdTostring As String = ".tostring("""

    Dim txtSelection As String() = System.Text.RegularExpressions.Regex.Split(textSelection.Text.Trim, "\+\s_[+\n\r\t]|&\s_[+\n\r\t]|\+|&")
    Dim hardStrings As String = String.Empty
    Dim valueStrings As String = String.Empty
    Dim counter As Int16 = 0

    For Each str As String In txtSelection
        Dim tmpString As String = str.Trim
        If tmpString.StartsWith("""") Then
            hardStrings &= tmpString.Substring(1, tmpString.Length - 2)
        Else
            Dim fmt As String = String.Empty
            Dim indxToString As Int32 = 0

            If tmpString.ToLower.Contains(fmtdTostring) Then
                indxToString = tmpString.ToLower.IndexOf(fmtdTostring)
                fmt = tmpString.Substring(indxToString + 11, tmpString.Length - tmpString.ToLower.IndexOf(""")", indxToString) - 1)
            End If

                valueStrings &= tmpString & delimt

            counter += 1
        End If
    Next

    If valueStrings <> String.Empty Then valueStrings = valueStrings.Substring(0, valueStrings.Length - delimt.Length)

    textSelection.Text = String.Format(output, hardStrings, valueStrings)
    DTE.UndoContext.Close()

End Sub
