txtBeautified.Text.Remove(txtBeautified.Text.LastIndexOf(","), 1)

我想在我的文本中找到","的最后一个索引,然后删除它,但它不起作用.任何的想法？txtBeautified是一个richtextbox.

考虑:

Private Function ViewPropertyCast(ByVal type As String) As String
  Select Case type
    Case "smallint"
      Return "Short"
    Case "nvarchar"
      Return "String"
    Case "int"
      Return "Integer"
    Case "float"
      Return "Double"
    Case "datetime"
      Return "Date"
    Case "bigint"
      Return "Long"
    Case "ntext"
      Return "String"
    Case "bit"
      Return "Boolean"
    Case "uniqueidentifier"
      Return "Guid"
  End Select
End Function

为什么ViewPropertyCast不在所有代码路径上返回值？
