int   i   =   dataGrid1.CurrentRowIndex   ;

            SqlConnection sqlcon=new SqlConnection("server=839B2FF55DCC463;database=cangku;uid=sa;pwd=123456");
            sqlcon.Open();
            
            DialogResult a=MessageBox.Show(this,"是否删除该操作员信息？","信息提示",
                MessageBoxButtons.YesNo,MessageBoxIcon.Question);
            switch(a)
            {
                case DialogResult.Yes:
                {   
                    SqlDataAdapter1 s=new SqlDataAdapter(sql,sqlcon);
                    sqlDataAdapter1.Update(dataSet11,"操作员")   ;  
                    this.Show();
