EntityFramework 4使用存储过程分页

 CREATE PROC usp_OrgPage_SQL
 @pageIndex INT,
 @pageSize INT,
 @totalCount INT OUTPUT
 AS
     BEGIN
         SET @totalCount = (SELECT COUNT(*) FROM dbo.Organization)
         SELECT * FROM
         (
         SELECT *,ROW_NUMBER() OVER(ORDER BY OrganizationID DESC)AS row FROM dbo.Organization
         )AS res
         WHERE res.row BETWEEN @pageSize * (@pageIndex - 1) + 1 AND @pageSize * @pageIndex
     END

 public List<OrganizationModel> SelectPageList(int pageIndex, int pageSize, out int totalCount)
         {
             var cmd = DbContext.Connection.CreateCommand();
             cmd.CommandText = "kydContext.usp_OrgPage_SQL";
             cmd.CommandType = System.Data.CommandType.StoredProcedure;
             cmd.Parameters.Add(new EntityParameter
             {
                 ParameterName = "pageIndex",
                 Value = pageIndex
             });
             cmd.Parameters.Add(new EntityParameter
             {
                 ParameterName = "pageSize",
                 Value = pageSize
             });
             cmd.Parameters.Add(new EntityParameter
             {
                 ParameterName = "totalCount",
                 Direction = System.Data.ParameterDirection.Output
             });

             cmd.Connection.Open();
             DbDataReader reader = cmd.ExecuteReader(System.Data.CommandBehavior.SequentialAccess);
             List<OrganizationModel> organizationModelList = new List<OrganizationModel>();
             while (reader.Read())
             {
                 OrganizationModel organizationModel = new OrganizationModel();
                 organizationModel.OrganizationID = reader.GetInt32(reader.GetOrdinal("OrganizationID"));
                 organizationModel.OrganizationName = reader.GetString(reader.GetOrdinal("OrganizationName"));
                 organizationModelList.Add(organizationModel);
             }
             reader.Close();
             totalCount = Convert.ToInt32(cmd.Parameters["totalCount"].Value);
             cmd.Connection.Close();
             return organizationModelList;
         }

对于EntityFramework调用存储过程通常想到的是"Context.ExcuteFunction()"。

但是ExcuteFunction不返回任何结果，只有影响的行数，所以如果是通过存储过程实现分页及查询还得使用传统的command方式
