    事前準備

    實體-_马岛战争电影:

    public enum Gender
    {
        Man = 1,
        Woman
    }
    
    [Table('Users')]
    public class User
    {
        [Sequence('USERS_AUTOID')]
        public int Id { get; set; }
        public string Name { get; set; }
        public Gender? Gender { get; set; }
        public int? Age { get; set; }
        public int? CityId { get; set; }
        public DateTime? OpTime { get; set; }
    }
    
    public class City
    {
        [Column(IsPrimaryKey = true)]
        public int Id { get; set; }
        public string Name { get; set; }
        public int ProvinceId { get; set; }
    }
    
    public class Province
    {
        [Column(IsPrimaryKey = true)]
        public int Id { get; set; }
        public string Name { get; set; }
    }

    因為框架本身需要與具體的數據庫驅動解耦|-_ebase官网,所以 OracleContext 構造函數需要一個 IDbConnectionFactory 的參數-__亿彩彩票怎么样,IDbConnectionFactory 接口隻有一個 CreateConnection() 方法|__随意贴,必須先建個類__-舞龙舞狮的由来,實現 CreateConnection 方法||莱州中考成绩查询:

    public class OracleConnectionFactory : IDbConnectionFactory

        {
            this._connString = connString;
        }
        public IDbConnection CreateConnection()
        {
            OracleConnection oracleConnection = new OracleConnection(this._connString);
            OracleConnectionDecorator conn = new OracleConnectionDecorator(oracleConnection);
            return conn;
        }
    }

    由於我用的是 Oracle.ManagedDataAccess 數據庫驅動|-106苹果下载,OracleConnection 創建的 DbCommand 默認是以順序方式綁定參數|-|七彩尾房超市,所以||露春红,上述例子使用了裝飾者模式對 OracleConnection 封裝了一遍__藏秘虫草双参,主要就是修改 DbCommand 參數綁定方式-||智行彩票官网。OracleConnectionDecorator 的定義在官網API文檔和 Github 上的 demo 中都有--易彩堂安全吗,在這就不貼了--_lame exe,不然太占篇幅_-_抓蛇狂人奥斯丁。

    創建一個 DbContext_铁路调度系统:

    OracleContext context = new OracleContext(new OracleConnectionFactory(connString));

    再創建一個 IQuery<T>_|陕西地震信息网:
