ServiceStack.OrmLite 入门（一）

软件环境：

• Win7 x64 SP1
• SQL Server 2008r2
• Visual Studio 2017 Professional

目标：取出示例数据库 ReportServer 的表 Roles 中的所有记录并显示。

步骤：

一、添加软件包

使用NuGet添加以下软件包：

ServiceStack

ServiceStack.OrmLite

二、定义表类

根据表Roles来定义对应的C#类：

    [Serializable]
    [Alias("Roles")]
    public class Role
    {
        public string RoleID { get; set; }
        public string RoleName { get; set; }
        public string Description { get; set; }
        public string TaskMask { get; set; }
        public int RoleFlags { get; set; }
    }

三、获取表数据并输出

            var dbFactory = new OrmLiteConnectionFactory("Server=(local);Database=ReportServer;Trusted_Connection=True;", SqlServerDialect.Provider);
            using(var db = dbFactory.Open())
            {
                var roles = db.Select<Role>();
                "Roles: {0}".Print(roles.Dump());
            }

完整的代码如下：

// RolesDemo.cs

using System;

using ServiceStack.Text;    // for string.Print()
using ServiceStack.OrmLite;
using ServiceStack.DataAnnotations;     // for [Alias()]

namespace ConsoleApp1
{
    [Serializable]
    [Alias("Roles")]
    public class Role
    {
        public string RoleID { get; set; }
        public string RoleName { get; set; }
        public string Description { get; set; }
        public string TaskMask { get; set; }
        public int RoleFlags { get; set; }
    }

    class RolesDemo
    {
        public static void Run()
        {
            var dbFactory = new OrmLiteConnectionFactory("Server=(local);Database=ReportServer;Trusted_Connection=True;", SqlServerDialect.Provider);
            using(var db = dbFactory.Open())
            {
                var roles = db.Select<Role>();
                "Roles: {0}".Print(roles.Dump());
            }
        }
    }
}

// Program.cs

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            RolesDemo.Run();
        }
    }
}
