递归输出系统菜单到DropDownList

<div> public class SysMenuManage
 {
 /// <summary>
 /// 通过父节点id得到系统菜单
 /// </summary>
 public DataTable GetSysMenuByParentId(int parentId)
 {
 string sql = "select * from y_sysMenu where <a href="mailto:m_parentId=@m_parentId">m_parentId=@m_parentId</a>";
 return SQLLinkDatabase.Query(sql, new SqlParameter("@m_parentId", parentId)).Tables[0];
 }
<div> /// <summary>
 /// 绑定菜单
 /// </summary>
 public void BindSysMenu(int parentId,DropDownList ddlList)
 {
 DataTable dt=GetSysMenuByParentId(parentId);
 foreach (DataRow dr in dt.Rows)
 {
 ListItem li = new ListItem();
 li.Text="╋"+dr["M_Name"].ToString();
 li.Value = dr["M_UID"].ToString();
 ddlList.Items.Add(li);
 BindSysMenuChild(Judge.get_Int(dr["M_UID"].ToString()), ddlList, "├&mdash;");
 }
 }
<div> /// <summary>
 /// 绑定子菜单
 /// </summary>
 public void BindSysMenuChild(int parentId,DropDownList ddlList,String separtor)
 {
 DataTable dt = GetSysMenuByParentId(parentId);
 foreach (DataRow dr in dt.Rows)
 {
 ListItem li = new ListItem();
 li.Text = separtor+dr["M_Name"].ToString();
 li.Value = dr["M_UID"].ToString();
 string separtor_= separtor+"&mdash;&mdash;";
 ddlList.Items.Add(li);
 BindSysMenuChild(Judge.get_Int(dr["M_UID"].ToString()), ddlList, separtor_);
 
 } 
 }
 }
