c#调用带有自定义表结构的存储过程

1、新建自定义表结构

注意字段的顺序要一致 类型要一样 不然会出错 

CREATE TYPE [dbo].[HBForHBGHDR] AS TABLE(
[序号] [int] NULL,
[客户编号] [varchar](15) NULL
)
GO

　　

2、建立存储过程

alter PROCEDURE UP_DRGHHB
  @HBList HBForHBGHDR readonly,
  @returnCode varchar(10) output,
  @returnMsg varchar(50) output
AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;
   declare @rowcount int
   set @returnCode=1
   select @rowcount=count(1) from @HBList
   --set @returnMsg=(select top 1 [客户编号] from @HBList)
   update jc_hb set yl5=1 where khbh in(select [客户编号] from @HBList)
   set @returnMsg='总共提交条数：'+convert(varchar(10),@rowcount)+',修改成功:'+ convert(varchar(10),@@rowcount)+'条'
END
GO

　3、调用存储过程

 string returnCode = string.Empty;
            string returnMsg = string.Empty;
            SqlParameter[] paras = new SqlParameter[]{
                new SqlParameter("@returnCode",returnCode),
                new SqlParameter("@returnMsg",returnMsg),
                new SqlParameter("@HBList",dt)
                };
            paras[0].Direction = ParameterDirection.Output;
            paras[1].Direction = ParameterDirection.Output;
            paras[1].Size = 50;
            paras[2].TypeName = "HBForHBGHDR";

            DataSet ds = DbHelperSQL.RunProcedure("[UP_DRGHHB]", paras, "tb1");
            returnMsg = paras[1].Value.ToString();
            returnCode = paras[0].Value.ToString();
            if (returnCode != "1")
            {
                this.lblError.Text = "批量插入数据失败：" + returnMsg;
            }
            else
                this.lblError.Text = "批量插入数据成功：" + returnMsg;
