ASP.NET调用存储过程

Creat PROCEDURE [dbo].[abc]
@s varchar(8000),
@e varchar(8000)
AS
declare @sql1 varchar(8000)
set @sql1 = 'select Name as n'
select @sql1 = @sql1 + ',sum(case Subject when ''' + Subject + ''' then Result else 0 end) [' + Subject + ']'
from (select distinct Subject from cj) as a
set @sql1 ='select Name,sum(result) 总分,'+right(@sql1,len(@sql1)-17)+' from cj WHERE RESULT BETWEEN '+@s+' AND '+@e+' group by name'
exec(@sql1)
exec abc 70,80

using System.Data.SqlClient;
using System.Configuration;
using System.Data;
protected void Button1_Click(object sender, EventArgs e)
{
　　using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
　　{
　　conn.Open();
　　SqlDataAdapter sqldap = new SqlDataAdapter();
　　SqlCommand cmm = new SqlCommand();
　　cmm.Connection = conn;
　　cmm.CommandType = CommandType.StoredProcedure;
　　cmm.CommandText = "abc";
　　cmm.Parameters.Add("s", SqlDbType.VarChar);
　　cmm.Parameters.Add("e", SqlDbType.VarChar);
　　cmm.Parameters["s"].Value = TextBox1.Text;
　　cmm.Parameters["e"].Value = TextBox2.Text;
　　sqldap.SelectCommand = cmm;
　　DataTable dt = new DataTable();
　　sqldap.Fill(dt);
　　GridView2.DataSource = dt;
　　GridView2.DataBind();
　　}
}

就这么处理！
