Visual studio 2010 Visual Studio 2010字符串。格式异常

我正试图使用format.string将列插入列表框，但它似乎不起作用，“输入字符串的格式不正确”。我已经没有办法解决这个问题了，在谷歌上真的找不到任何解决方案。所以我决定在这里问，顺便说一句，这是我的代码

Public Class Form1
Dim stddetails As String = "{0, -20}{1, -20}{2, -20}{3, -20}(4, -20}{5, -20}{6, -20}"

    lstoutput.Items.Add(String.Format(stddetails, "Customer ID", "Nama Depan", "Nama Belakang", "Pemesanan", "Tanggal Pemesanan", "Pembayaran", "Total"))

    cmbpemesanan.Items.Add("Pilih Cara Pemesanan")
    cmbpemesanan.Items.Add("Telepon")

非常感谢您的帮助。

第2行出现语法错误

您使用了“（”而不是“{”

替换

Dim stddetails As String = "{0, -20}{1, -20}{2, -20}{3, -20}(4, -20}{5, -20}{6, -20}"

标题提到了NetBeans，代码是使用WinForms的Visual Basic.NET，标签是Visual Studio 2010。这真是个难题！抱歉，一定是把它和我的上一个问题混在一起了。.编辑，谢谢你指出这一点。您好，欢迎使用StackOverflow。为了避免浪费大家的时间，如果问题可以简化为最简单的形式，这会很有帮助。例如，

Form1\u Load

声明和各种

项是否真的需要添加
调用，或者问题是否可以通过调用String.Format的简单控制台程序重现？请参阅和，以获取有关有效问题的更多提示。噢，我太马虎了！不敢相信这是一个打字错误，谢谢你的回复把它画出来！
