通过数据库网格查看器删除选定行

Question

我需要能够通过数据网格查看器删除一行及其内容，我编写的当前代码仅删除第 0 行的内容，我无法在选定的行中执行此操作。

Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
    Dim dataAdapter As New OleDbDataAdapter
    Dim DataTable As New DataTable
    Dim DataSet As New DataSet
    Try

        DataSet.Tables.Add(DataTable)
        Connection.Open()
        dataAdapter = New OleDbDataAdapter("SELECT * FROM Students", Connection)
        dataAdapter.Fill(DataTable)
        DataTable.Rows(0).BeginEdit()
        DataTable.Rows(0).Delete()
        DataTable.Rows(0).EndEdit()
        Dim Commandbuilder As New OleDbCommandBuilder(dataAdapter)
        dataAdapter.Update(DataTable)
        dgrStudentDatabaseViewer.DataSource = DataTable.DefaultView
        Connection.Close()
    Catch ex As Exception
        MessageBox.Show(ex.Message)
        Connection.Close()
    End Try
End Sub

提前致谢。

使用此代码，您可以删除当前选定的行：

DataTable.Rows(DataGridView1.CurrentRow.Index).BeginEdit()
DataTable.Rows(DataGridView1.CurrentRow.Index).Delete()
DataTable.Rows(DataGridView1.CurrentRow.Index).EndEdit()
