combobox控件的存储使用~~

Question

        private void toolStripButton8_Click(object sender, EventArgs e)
        {
BindingNavigator bn = this.学生信息DataSet.stuinfo;
bn.RowFilter = "userno='" + this.txtSuserno.Text + "'";
dt[0]["sex"] = this.comSsex.SelectedValue;
this.stuinfoTableAdapter.Update(this.学生信息DataSet.stuinfo);
            MessageBox.Show("修改成功");
        }
代码不完全 具体是用comSsex.SelectedValue 里面放了性别男、女。
我想把男女存储到表里面。例子
        
            DataTable ds = new DataTable();
            ds.Columns.Add("roleid", typeof(Int16));
            ds.Columns.Add("rolename", typeof(string));
            DataRow dx;
                dx = ds.NewRow();
                dx["roleid"] = 1;
                dx["rolename"] = "组长";
                ds.Rows.Add(dx);
                dx = ds.NewRow();
                dx["roleid"] = 0;
                dx["rolename"] = "组员";
                ds.Rows.Add(dx);
           
            this.cmdRole.DataSource = ds;
            this.cmdRole.DisplayMember = "rolename";
            this.cmdRole.ValueMember = "roleid";DataView dv = new DataView(this.studentDbDataSet.groups);
                dv.RowFilter = "stuid='" + this.textBox1.Text + "'";
                dv[0]["stuid"] = this.textBox1.Text;
                dv[0]["stugroup"] = this.cmdGroup.SelectedValue;
                dv[0]["roles"] = this.cmdRole.SelectedValue;
                this.groupsTableAdapter.Update(this.studentDbDataSet);
                MessageBox.Show("数据添加成功");这个例子用的是dataview拖名字 我那个没有用dataview
不知道要怎么改。。哪位高手教教
