Answer 1

I know this is an old question but it came up in my search results when I was trying to create a solution for my own project. I thought I needed to search a StringBuilder.ToString's method results but then I realized I could just call methods on the StringBuilder itself. My situation may not be the same as yours, but I though I'd share:

Private Function valueFormatter(ByVal value As String) As String
    ' This will correct any formatting to make the value valid for a CSV format
    '
    ' 1) Any value that as a , in it then it must be wrapped in a " i.e. Hello,World -> "Hello,World"
    ' 2) In order to escape a " in the value add a " i.e. Hello"World -> Hello""World
    ' 3) if the value has a " in it then it must also be wrapped in a " i.e. "Hello World" -> ""Hello World"" -> """Hello World"""
    ' 
    ' VB NOTATAION 
    ' " -> """"
    ' "" -> """"""

    If value.Contains(",") Or value.Contains("""") Then
        Dim sb As New StringBuilder(value)
        If value.Contains("""") Then sb.Replace("""", """""")
        sb.Insert(0, """").Append("""")
        Return sb.ToString
    Else
        Return value
    End If
End Function
