Dim StrTest(50)
        Dim mc(50)
        Dim j As Integer
        For j = 0 To Val(Zds) - 1
            StrTest(j) = oIni.INIRead(Application.StartupPath & "\config.ini", "信息", j + 1)
            mc(j) = Split(StrTest(j), ",")
            MsgBox(mc(j))  '错误提示：参数“Prompt”无法转换为类型“String”。
        Next j

返回system.string[]是什么原因?
