Question

下面是我将数据输入数组并检索信息的代码

输入数据似乎没有问题但是当我点击按钮来检索信息时，它只是在文本框中显示0。

Public Class Form1

    Dim Array(20) As String

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub

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

        Dim counter As Integer

        For counter = 0 To ListBox1.Items.Count - 1
            Array(counter) = txtEnterMarks.Text(counter)
        Next

        Label1.Text = "omfg"
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

        For counter = 0 To Array.Length - 1
            ListBox1.Items.Add(Array(counter))
        Next
    End Sub
End Class

再次尝试这个不同的答案

Structure Student    
    Dim Name As String
    Dim Mark As Integer
End Structure

将输入保存在其中：

Dim StudentsInfo as New List(Of Student)
Dim si As New Student

si.Name = txtEnterName.Text
si.mark = val(txtEnterMark.Text)
StudentsInfo.Add(si)

从StudentsInfo获取价值

txtEnterName.Text = StudentsInfo(0).Name
txtEnterMark.Text = StudentsInfo(0).mark.ToString

关于将其保存到ListView ..再次尝试Google先生......
