C#动态创建实例化泛型对象，实例化新对象 new()

普通类实例化：

Assembly assembly = Assembly.Load("Dsh.Data");
Type type = assembly.GetType("Dsh.Data.SqlServer");
Interface.IDal<TEntity> Dal = (Interface.IDal<TEntity>)Activator.CreateInstance(type, true);

泛型类实例化：（注意`1）

Assembly assembly = Assembly.Load("Dsh.Data");
Type type = assembly.GetType("Dsh.Data.SqlServer" + "`1").MakeGenericType(typeof(TEntity));
Interface.IDal<TEntity> Dal = (Interface.IDal<TEntity>)Activator.CreateInstance(type, true);

泛型类（多个泛型）实例化：（注意`2）

Assembly assembly = Assembly.Load("Dsh.Data");
Type type = assembly.GetType("Dsh.Data.SqlServer" + "`2").MakeGenericType(typeof(TEntity), typeof(TPrimaryKey));
Interface.IDal<TEntity, TPrimaryKey> = (Interface.IDal<TEntity, TPrimaryKey>)Activator.CreateInstance(type, true);
