IModel

It might be nice if the user was allowed to inherit their model from an `IModel` interface that looked something like this:
```csharp
interface IModel
{
int/Guid Id { get; set;}
}
```

This would allow the code not to have to use the `Type.GetProperty()` method and provide more IntelliSense.

未指定文件或测试入口点。首先定位调用 Type.GetProperty() 的模型处理代码，然后确定支持 int 或 Guid 标识符的 IModel 接口应如何适配；完成的标准是模型处理可以使用该接口，并提供所请求的 IntelliSense 改进。
