ORM框架：Dapper的使用

1. Nuget安装Dapper

2. 使用

static void Main(string[] args)
{
    using (OracleConnection connection = new OracleConnection(Helper.OracleHelper.ConnectionString_Default))
    {

        var m = connection.Query<UserInfo>("select * from usertable").ToList();
        var x = connection.Query<UserInfo>("select * from usertable where id=:id", new { id = 2 }).ToList();
        Console.WriteLine(x.Count);
        foreach (UserInfo user in x)
        {
            Console.WriteLine(user.name);
        }

        UserInfo user1 = new UserInfo() { id=3,name="zl"};
        var y = connection.Execute("insert into usertable (id,name) values(:id,:name)", user1);
        Console.WriteLine(y);

        OracleTransaction transaction = connection.BeginTransaction();
        try
        {
            //执行代码...
            //执行代码...
            transaction.Commit();
        }
        catch (Exception e)
        {
            transaction.Rollback();
        }

        Console.WriteLine("");
    }

    var a = ConfigurationManager.ConnectionStrings["DemoConnString"];
    DataTable dt = Helper.OracleHelper.ExecuteDataTable("Select * From Dual");

    Console.WriteLine("");
}
