在.NET里怎么执行带参数的存储过程

           string strconn = System.Configuration.ConfigurationSettings.AppSettings["connStr"].ToString();
            //定义一个连接对象
            SqlConnection conn = new SqlConnection(strconn);
            int PageIndex = 1;
            int PageSize = 10;
            int PageCount;
            string ViewName="Record";
            string Field = "*";
            //定义一个SqlCommand 对象
            SqlCommand comm = new SqlCommand("Pagination",conn);
             //定义SqlCommand 对象的执行命令为存储过程
            comm.CommandType = CommandType.StoredProcedure;
            //添加一个参数,并指出其类型
            comm.Parameters.Add("@PageIndex",SqlDbType.Int);
            //给参数@PageIndex赋值
            comm.Parameters["@PageIndex"].Value=PageIndex;

            comm.Parameters.Add("@PageSize",SqlDbType.Int);
            comm.Parameters["@PageSize"].Value=PageSize;

            comm.Parameters.Add("@RecordCount",SqlDbType.Int);
             //如果是输出参数,显式指出
            comm.Parameters["@RecordCount"].Direction=ParameterDirection.Output;

            comm.Parameters.Add("@PageCount", SqlDbType.Int);
            comm.Parameters["@PageCount"].Direction = ParameterDirection.Output;

            comm.Parameters.Add("@ViewName", SqlDbType.VarChar, 50);
            comm.Parameters["@ViewName"].Value = ViewName;

            comm.Parameters.Add("@Field", SqlDbType.VarChar, 200);
            comm.Parameters["@Field"].Value = Field;

            conn.Open();

            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = comm;
            comm.ExecuteNonQuery();
            DataSet ds = new DataSet();
            da.Fill(ds);
           //取得输出参数,注意用流读取时,不能成功取出参数
            PageCount = System.Convert.ToInt32(comm.Parameters["@PageCount"].Value);

            string strPageCount = comm.Parameters["@PageCount"].Value.ToString();
