C#数据绑定BindingSource，如何使用过滤后的数据集

设置数据集及过滤器，这样就可以在不同的视图下呈现

dataTable = BO_Team.GetDataList_Member();
bind_Member.DataSource = dataTable;  //数据绑定

bind_Member.Filter = string.Format("team_sn='{0}'", BO_member.Team_Sn);  //设置筛选条件

通过DataView .ToTable()获取过滤后的数据集

        void updateMembers()
        {
            string members = "";
            DataView dv;
            dv = ((DataTable)bind_Member.DataSource).DefaultView;
            dataTable = dv.ToTable(true, "staff_name");
            if (dataTable.Rows.Count == 0)
            { members = ""; }
            else
            {
                members = dataTable.Rows[0][0].ToString();
                for (int i = 1; i < dataTable.Rows.Count; i++)
                {
                    members += "，" + dataTable.Rows[i][0].ToString();
                }
            }
            txtMembers.Text = members;
            bind_Team.EndEdit();
        }
