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
goALTER 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。
