请教个datalist绑定存储过程参数的问题

存储过程代码如下：
-----------------------------------------------------------------------------------------------------
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER PROCEDURE [dbo].[ReadIntro]
@pbody varchar(50),
@pclicks varchar(50),
@pwriter varchar(50),
@ptime varchar(50)
AS
BEGIN

SET NOCOUNT ON;

SELECT @pbody as cont,bodyclix as clicks,@ptime as updatetime,@pwriter as writer from intro
END
------------------------------------------------------------------------------------------------------
cs文件如下：
------------------------------------------------------------------------------------------------------
  String strconstring = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
  SqlConnection connection_intro = new SqlConnection(strconstring);

  SqlCommand command_intro = new SqlCommand();
  command_intro.Connection = connection_intro;
  command_intro.CommandText = "Readintro";
  command_intro.Parameters.Add(new SqlParameter("@pbody ", SqlDbType.VarChar,50));
  command_intro.Parameters["@pbody "].Value = "body";
  command_intro.Parameters.Add(new SqlParameter("@pclicks ", SqlDbType.VarChar, 50));
  command_intro.Parameters["@pclicks "].Value = "bodyclix";
  command_intro.Parameters.Add(new SqlParameter("@ptime ", SqlDbType.VarChar, 50));
  command_intro.Parameters["@ptime "].Value = "bodytime";
  command_intro.Parameters.Add(new SqlParameter("@pwriter ", SqlDbType.VarChar, 50));
  command_intro.Parameters["@pwriter "].Value = "bodywriter";
  command_intro.CommandType = CommandType.StoredProcedure;
   
  SqlDataAdapter adapter_intro = new SqlDataAdapter(command_intro);
  DataTable data_intro = new DataTable();
  adapter_intro.Fill(data_intro);

  DataList1.DataSource = data_intro;
  DataList1.DataBind();
--------------------------------------------------------------------------------------------------------
aspx文件如下：
--------------------------------------------------------------------------------------------------------
<asp:DataList ID="DataList1" runat="server" ShowFooter="False" CellPadding="0" CellSpacing="0" ShowHeader="False" Width="100%">
  <ItemTemplate>
  <div class="author">点击数：<span><asp:Label id="Label1" runat="server" Text='<%# Eval("clicks") %>' ></asp:Label></span>次&nbsp;&nbsp;
  作者：<span><asp:Label id="Label2" runat="server" Text='<%# Eval("writer") %>' ></asp:Label></span>&nbsp;&nbsp;
  添加时间：<span><asp:Label id="Label3" runat="server" Text='<%# Eval("updatetime") %>' ></asp:Label></span>&nbsp;&nbsp;
  </div>
  <div class="con_text"> 
  <div class="c_content_text"> 
  <div class="c_content_overflow" id="fontzoom">
  <p style="line-height: 18pt; text-indent: 21pt; background: white;"><asp:Label id="Label4" runat="server" Text='<%# Eval("cont") %>' ></asp:Label>
  <br/>
  <br/>
  </div> 
  </div> 
  </div>
  </ItemTemplate>
  </asp:DataList>

我希望实现的是：给存储过程输入参数作为字段名，然后用datalist绑定查询出来的结果，可是结果显示的是我输入参数的值，即body,bodyclix,bodywrier,bodytime，没显示具体的查询结构。请各位帮忙，十分感谢！
非常着急。

SQL code

SELECT 'bodyclix' as cont,'bodyclix'as clicks,' bodytime' as updatetime,'bodywrier' as writer from intro

你执行的效果相当于这样..
