在实体中创建非映射属性（实体框架） [英] Creating a non mapped property in an entity (entity framework)

问题描述

我想在从数据库映射的我的一个实体上创建一个自定义属性，但是这个属性没有映射到数据库，我使用部分类创建了属性，但是当尝试编译时，我收到一个错误，告诉我属性未映射。有什么属性还是我应该添加的东西？感谢提前。

解决方案

使用部分类添加要添加的属性或方法。例如

 命名空间WhateverNamespaceYourEntityModelIsIn 
 {
 public partial class TheNameOfYourEntity 
 {
 public string MyNewProperty {get;组; } 
} 
} 
  

I want to create a custom property on one of my entities mapped from the database, however this property is not mapped to the database, I created the property using partial classes but when trying to compile I get an error telling me that the property is not mapped. Is there an attribute or something I should add? Thanks in advance.

解决方案

Use partial classes to add the properties or methods you want added. E.g.

namespace WhateverNamespaceYourEntityModelIsIn
{
    public partial class  TheNameOfYourEntity
    {
          public string MyNewProperty { get; set; }
    }
}

and that should do you.
