我正在使用ASP.NET MVC 4使用Entity FrameWork来执行数据库级操作 [英] Im working with ASP.NET MVC 4 using Entity FrameWork to perform database level operations

问题描述

我使用Entity FrameWork使用ASP.NET MVC 4来执行数据库级操作，现在我必须对此业务类进行验证，如果我将一个单独的类作为模型来绑定这些属性以查看我是否可以使用相同的由实体框架生成的类

Im working with ASP.NET MVC 4 using Entity FrameWork to perform database level operations, now i have to do validations for this business class, should i take a seperate class as model to bind these properties to view could i use the same class that was generated by entity framework

        public Nullable<int> SchoolID { get; set; }
        public Nullable<int> WareHouseID { get; set; }
        public Nullable<int> YearID { get; set; }
}
}

推荐答案

数据首次验证 [ ^ ]



验证EF生成的模型类 [< a href =http://jnye.co/Posts/19/adding-validation-to-models-created-by-entity-framework-database-first-ctarget =_ blanktitle =New Window> ^ ]



在具有元数据属性的类的相同.cs文件中创建部分类将允许您应用验证。

Data first validation[^]

Validation to EF generated model classes[^]

Creating a partial class in the same .cs file for the class with Metadata attribute would allow you to apply validations.

[MetadataType(typeof(PayrollMarkupMetadata))
public partial class INVT_Item
{
  ...
}

希望这会有所帮助。

谢谢
