Asp.net 使用GridView删除记录

我在删除记录时遇到了一些问题。我使用VB.net和Access数据库。当我尝试运行这个程序时，并没有出现错误，但数据库中的记录并没有被删除。有一个类要删除记录，该类将调用另一个方法，即call DeleteMultipleRecords。这是我的代码，希望有人能帮我解决这个问题

    Dim idCollection As New StringCollection()
    Dim strID As String = String.Empty
    'Loop through GridView rows to find checked rows 
    For i As Integer = 0 To i < GridView1.Rows.Count - 1
        Dim chkDelete As CheckBox = DirectCast(GridView1.Rows(i).Cells(0).FindControl("chkSelect"), CheckBox)
        If chkDelete IsNot Nothing Then
            If chkDelete.Checked Then

                strID = GridView1.Rows(i).Cells(1).Text
                idCollection.Add(strID)

Protected Sub btnDelete\u Click（ByVal sender作为对象，ByVal e作为事件参数）处理btnDelete。单击
'创建字符串集合以存储要删除的记录的ID
Dim idCollection作为新的StringCollection（）
Dim strID As String=String.Empty
'循环GridView行以查找选中的行
对于i As Integer=0到i

您应该更改这些行才能工作：

For Each id As String In idCollection

    IDs += "'" + id.ToString() & "',"
Next

Try

    Dim strIDs As String = IDs.Substring(0, IDs.LastIndexOf(""))
    Dim strSql As String = ("Delete from Details WHERE ID IN (" & strIDs & ")")

---

但是：此代码容易出错，您必须在2012年使用SQL参数。

请在

Dim strSql As String = ("Delete from Details WHERE ID IN (" & strIDs & ")")

然后运行您的应用程序，并将watch添加到strSql，当遇到断点时，按F11，然后您可以看到strSql的内容，复制sql语句并在Access数据库中运行查询，并查看它是否工作

---

PS：尝试将[]添加到表名，从[详细信息]中删除。

我已经更改了，但仍然相同，没有错误，但没有删除记录
