我不断收到“输入字符串的格式不正确”错误

Question

我正在学习有关在列表框中创建表格显示的 vb.net 教程。他们的代码似乎运行良好，但为什么我的代码不断出现此错误？

这是我的代码：

Public Class AdminTab

    Dim pes As String = "{0, -10}{1, -20}{2, -20}{3, - 15}"

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Me.Hide()
    End Sub

    Private Sub sadasda_SelectedIndexChanged(sender As System.Object, e As System.EventArgs)

    End Sub

    Private Sub AdminTab_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        VL.Items.Add(String.Format(pes, "Name", "Gender", "Date", "Reason"))
    End Sub
End Class

我唯一尝试的就是重新启动电脑并在线搜索帮助。

Answer 1

Dim pes As String = "{0, -10}{1, -20}{2, -20}{3, - 15}"

负号之前可能允许有空格，但我相当确定负号和数字之间不允许有空格。几乎可以肯定至少应该是这样的：

Dim pes As String = "{0, -10}{1, -20}{2, -20}{3, -15}"

但甚至可能是这样：

Dim pes As String = "{0,-10}{1,-20}{2,-20}{3,-15}"
