dataGridView显示删除成功了，但是数据库里面数据还在
string strConn = @ "Provider = Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\data.mdb ";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();

int ID = Int32.Parse(this.dataGridView1.CurrentRow.Cells[0].Value.ToString());
string selectStr = "delete from shop where id = " + ID + " ";
OleDbCommand thisComm = conn.CreateCommand();
thisComm.CommandText = selectStr;
try
{
thisComm.ExecuteNonQuery();
}
catch
{
throw;
}
finally
{
thisComm.Dispose();
conn.Close();
}

this.dataGridView1.Rows.Remove(this.dataGridView1.CurrentRow);

在dataGridView上面实现数据已经没有了，但是打开数据库看下，那条数据还在。。。

[解决办法]
ID是不是取的不对而使
delete from shop where id = " + ID + " ";
没有正确的执行!
