C# SQL封装（二）

接 C# SQL封装（一）

开始操作数据库的测试 ：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using DBDome.com;
using DBDome.model;
using System.Data.SqlClient;
using System.Data;

namespace DBDome
{
    class Program
    {
        static void Main(string[] args)
        {
            User kayer_new = new User();
            kayer_new.name = “kayer”;
            kayer_new.sex = 1;
            kayer_new.lv = 1;
            kayer_new.username = “Kayer”;
            kayer_new.userpwd = “123”;

            string into_sql = SQL_Structure.ADD_T_SQL<User>(kayer_new);
            Console.WriteLine(into_sql);
           
            SqlParameter[] a = SqlParameter_Structure.ADD_T_SQL<User>(kayer_new);
            string c =  SqlHelper.connectionString;
            Console.WriteLine(c);
           
            int i = SqlHelper.ExecteNonQuery(CommandType.Text, into_sql, a);
            if (i > 0)
            {
                Console.WriteLine(“执行操作成功”);
            }
            else
            {
                Console.WriteLine(“执行操作失败”);
            }
            Console.Read();
        }
    }
}

结果 ：

删 – 改 – 查 的会陆续更新 ——
