在vb.net中访问Excel文件的用户,可以通过以下步骤进行操作:
完整的示例代码如下:
Imports Microsoft.Office.Interop.Excel
Imports System.Runtime.InteropServices
Public Class Form1
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim excelApp As New Application()
Dim workbook As Workbook = excelApp.Workbooks.Open("文件路径")
Dim worksheet As Worksheet = workbook.Sheets("工作表名称")
Dim cellValue As String = worksheet.Range("A1").Value
workbook.Close()
excelApp.Quit()
Marshal.ReleaseComObject(worksheet)
Marshal.ReleaseComObject(workbook)
Marshal.ReleaseComObject(excelApp)
End Sub
End Class
注意事项:
Marshal.ReleaseComObject()
方法释放资源。GC.Collect()
和GC.WaitForPendingFinalizers()
