1.实例表代码

/****** 对象:  Table [dbo].[Test]    脚本日期: 07/25/2008 10:37:05 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create TABLE [dbo].[Test](
[Identifier] [int] IDENTITY(1,1) NOT NULL,
[Name] [nchar](10) COLLATE Chinese_PRC_90_CI_AI NULL,
[Alias] [nvarchar](50) COLLATE Chinese_PRC_90_CI_AI NULL,
[Texts]  COLLATE Chinese_PRC_90_CI_AI NULL,
[Price] [decimal](18, 0) NULL,
[CreateDate] [datetime] NULL,
CONSTRAINT [PK_Test] PRIMARY KEY CLUSTERED
(
[Identifier] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

2.存储过程代码

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

3.C#调用存储过程代码

SqlCommand cmd = new SqlCommand();
SqlConnection cn = new SqlConnection(connectionString);
cn.Open();
cmd.Connection = cn;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "TestSel&#101;ct";
cmd.Parameters.Add(new SqlParameter("@PageSize", 1));
cmd.Parameters.Add(new SqlParameter("@CurrentPage",1));
cmd.Parameters.Add(new SqlParameter("@TotalPage",SqlDbType.Int));
cmd.Parameters["@TotalPage"].Direction = ParameterDirection.Output;
cmd.ExecuteNonQuery();
Console.Write("totalPage:{0}",cmd.Parameters["@TotalPage"].Value.ToString());
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
Console.Write("totolPage:{0}",reader[6]);
}
Console.Read();
