假設你使用的是DataGridView（雖然不確定），這裏有一些你必須看看的東西。

只是代碼片段：

private void button1_Click(object sender, EventArgs e) 
{ 
    System.Collections.ArrayList alv = new System.Collections.ArrayList(); 
    int i = 0; 
    private void button1_Click(object sender, EventArgs e) 
    { 
    OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<<Your Database Path>>"); 
    OleDbCommand cmd=new OleDbCommand(); 
    for (int i = 0; i < dataGridView1.Rows.Count; i++) 
    { 
    DataGridViewRow MyRow = dataGridView1.Rows[i]; 
    if (MyRow.Selected == true) 
    { 
    dataGridView1.Rows.RemoveAt(i); 
    try 
    { 
     conn.Open(); 
     //Here It Will Delete your Row From The Database Depending On Your Id.... 
     cmd.CommandText = "DELETE FROM MyTable Where Id=" + i + ""; 
     cmd.ExecuteNonQuery(); 
     conn.Close(); 
    } 
    catch(Exception ex) 
    { 
     MessageBox.Show(ex.ToString()); 
    } 
    } 
    } 
    } 
}
