一、 //返回阅读器
/// <summary>
/// 执行存储过程，返回SqlDataReader ( 注意：调用该方法后，一定要对SqlDataReader进行Close )
/// </summary>

/// <param name="parameters">存储过程参数</param>

SqlDataReader returnReader;
connection.Open();
SqlCommand command = BuildQueryCommand(connection, storedProcName, parameters);
command.CommandType = CommandType.StoredProcedure;
returnReader = command.ExecuteReader(CommandBehavior.CloseConnection);
return returnReader;

}
二、//返回表
public static DataTable RunProcedure1(string storedProcName, IDataParameter[] parameters)
{
SqlConnection connection = new SqlConnection(ConnectionString);
//SqlDataReader returnReader;
connection.Open();
SqlCommand command = BuildQueryCommand(connection, storedProcName, parameters);
command.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(command);//用SqlDataAdapter执行

DataTable table = new DataTable();//创建一张表

da.Fill(table);//填充表
// returnReader = command.ExecuteReader(CommandBehavior.CloseConnection);
return table ;

}
三、//获取返回值
public static string RunProcedure2(string storedProcName, IDataParameter[] parameters)
{
SqlConnection connection = new SqlConnection(ConnectionString);
//SqlDataReader returnReader;
connection.Open();
SqlCommand command = BuildQueryCommand(connection, storedProcName, parameters);
command.CommandType = CommandType.StoredProcedure;

command.Parameters.Add(new SqlParameter("@return", SqlDbType.Int));
command.Parameters["@return"].Direction = ParameterDirection.ReturnValue;
command.ExecuteNonQuery();
return command.Parameters["@return"].Value.ToString();

}
四、//获取输出值
public static string RunProcedure3(string storedProcName, IDataParameter[] parameters)
{
SqlConnection connection = new SqlConnection(ConnectionString);
//SqlDataReader returnReader;
connection.Open();
SqlCommand command = BuildQueryCommand(connection, storedProcName, parameters);
command.CommandType = CommandType.StoredProcedure;
//SqlParameter p3 = new SqlParameter("@phone", SqlDbType.Int);
command.Parameters["@phone"].Direction = ParameterDirection.Output;

//command.Parameters["@return"].Direction = ParameterDirection.ReturnValue;
command.ExecuteNonQuery();
return command.Parameters["@phone"].Value.ToString();

}

存储过程：
create proc proc_StadiumN
(
@Open_id nvarchar(50),
@Uname nvarchar(50),
@phone nvarchar(50) out

)
as
select @phone=Uname from Stadium_User Where Open_id=@Open_id

return '1'

2.
create proc [dbo].[proc_area](@status nvarchar(50),@Area_name nvarchar(50))
as
select Area_name from Area where Area_name=@Area_name
前台：
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server"></asp:GridView>
</div>
</form>
后台：

//返回阅读器
//IDataParameter[] dp = new IDataParameter[] { new SqlParameter("@Area_name", "虹口区"), new SqlParameter("@status", "1") };
//SqlDataReader dr = DBHelper.RunProcedure("proc_area", dp);

while(dr.Read())
{
Response.Write(dt["Area_name"]);
}
dr.Close();

//返回表
IDataParameter[] dp1 = new IDataParameter[] { new SqlParameter("@Open_id", "1"), new SqlParameter("@Uname", "段段"), new SqlParameter("@phone", "123") };

DataTable dt = DBHelper.RunProcedure2("proc_StadiumN", dp1);
//GridView1.DataSource = dt;
//GridView1.DataBind();
//获取返回值
IDataParameter[] dp1 = new IDataParameter[] { new SqlParameter("@Open_id", "1"), new SqlParameter("@Uname", "段段"), new SqlParameter("@phone", "123") };
string dt3 = DBHelper.RunProcedure2("proc_StadiumN", dp1);
Response.Write(dt3 );
//获取输出值
IDataParameter[] dp1 = new IDataParameter[] { new SqlParameter("@Open_id", "1"), new SqlParameter("@Uname", "段段"), new SqlParameter("@phone", "123") };
string dt4 = DBHelper.RunProcedure3("proc_StadiumN", dp1);
Response.Write(dt4 );

1.using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["LocalConnectionString"].ConnectionString))
{
conn.Open();
SqlCommand com = new SqlCommand();
com.Connection = conn;
com.CommandText = "uppoint_all";//这里的"uppoint_all"就是存储过程的名字
com.CommandType = CommandType.StoredProcedure;
com.ExecuteNonQuery();
conn.Close();
}

2.

SqlConnection conn = new SqlConnection(connectionstring);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = new SqlCommand();
da.SelectCommand.Connection = conn;
da.SelectCommand.CommandText ="NameOfProcedure（’para1’,’para2’,para3）";
da.Selectcommand.CommandType = CommandType.StoredProcedure;

3.

SqlCommand cmd = new SqlCommand("proc_3", con);//同上

cmd.CommandType = CommandType.StoredProcedure;//同上

SqlDataAdapter da = new SqlDataAdapter(cmd);//用SqlDataAdapter执行

DataTable table = new DataTable();//创建一张表

da.Fill(table);//填充表

return table;
