ListBox控件的项如何与Excel文件进行数据交互

要与Excel文件进行数据交互，可以使用ListBox控件的Items属性来添加、删除和编辑项，并使用Excel对象模型来读取和写入Excel文件中的数据。以下是一个示例代码，演示如何将ListBox控件的项与Excel文件进行数据交互：

Imports Excel = Microsoft.Office.Interop.Excel

Public Class Form1
    Dim xlApp As New Excel.Application
    Dim xlWorkBook As Excel.Workbook
    Dim xlWorkSheet As Excel.Worksheet

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        xlWorkBook = xlApp.Workbooks.Open("C:\path\to\your\file.xlsx")
        xlWorkSheet = xlWorkBook.Sheets(1)

        '将Excel文件中的数据添加到ListBox控件中
        For i As Integer = 1 To xlWorkSheet.Cells(1, 1).End(Excel.XlDirection.xlDown).Row
            ListBox1.Items.Add(xlWorkSheet.Cells(i, 1).Value)
        Next
    End Sub

    Private Sub btnSave_Click(sender As Object, e As EventArgs) Handles btnSave.Click
        '将ListBox控件中的项保存到Excel文件中
        For i As Integer = 0 To ListBox1.Items.Count - 1
            xlWorkSheet.Cells(i + 1, 1).Value = ListBox1.Items(i)
        Next

        xlWorkBook.Save()
    End Sub

    Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing
        '关闭Excel应用程序
        xlWorkBook.Close()
        xlApp.Quit()

        ReleaseObject(xlWorkSheet)
        ReleaseObject(xlWorkBook)
        ReleaseObject(xlApp)
    End Sub

    Private Sub ReleaseObject(ByVal obj As Object)
        Try
            System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
            obj = Nothing
        Catch ex As Exception
            obj = Nothing
        Finally
            GC.Collect()
        End Try
    End Sub
End Class

在这个示例中，我们首先在Form_Load事件中打开Excel文件并将其数据添加到ListBox控件中。然后在Save按钮的Click事件中，我们将ListBox控件中的项保存到Excel文件中。最后在Form_FormClosing事件中关闭Excel应用程序并释放资源。

请注意，此示例使用了Microsoft.Office.Interop.Excel命名空间来与Excel文件进行交互。请确保你的计算机上已安装Microsoft Office，并在项目中引用了Microsoft Excel 16.0 Object Library。
