LinkButton里面Command对象
我想点击LinButton的时候后台获取CommandName的参数，然后后台根据获取到的参数查询数据库中的数据，显示到前台的Label页面，为什么不管我怎么点击Linbutton按钮Label里面的值只会显示设备介绍查询到的内容呢？
下面是我的代码

C# code

 <p>                <a href="#">                    <asp:LinkButton ID="equipment" runat="server"   CommandName="设备介绍"  OnCommand="search_Click"  >设备介绍</asp:LinkButton></a></p>            <p>                <a href="#"><asp:LinkButton ID="web" runat="server"  CommandName="WEB组" OnCommand="search_Click"  >WEB组</asp:LinkButton></a></p>            <p>                <a href="#"><asp:LinkButton ID="xitong" runat="server" CommandName="系统开发组"  OnCommand="search_Click"  >系统开发组</asp:LinkButton></a></p>            <p>                <a href="#"><asp:LinkButton ID="ps" runat="server"  CommandName="美工"  OnCommand="search_Click"  >美工</asp:LinkButton></a></p>            <p>                <a href="#"><asp:LinkButton ID="contaction" runat="server"  CommandName="联系人" OnCommand="search_Click" >联系人</asp:LinkButton></a></p>后台代码： protected void search_Click(object sender, CommandEventArgs e)    {        string search = e.CommandName.ToString();        string strwhere = "select content from apply where title='" + search + "' ";        DataSet ds = gwolf_bll.GetMessage(strwhere);        content.Text = ds.Tables[0].Rows[0][0].ToString();            }  public static DataSet GetMessage(string SQLstring)        {            return gwolf_dal.Search(SQLstring);        }  public static DataSet Search(string SQLstring)        {            ConOpen();            try            {                Command = new MySqlDataAdapter(SQLstring, Sqlcon);                Command.Fill(myds, "chaxun");                              Command.Dispose();            }            catch(Exception)            {                throw;            }            finally            {                ConClose();                        }            return myds;        }
