# 12、自定义实体特性、与其他 ORM 共用特性
抛砖引玉以下的示例代码FreeSql 使用 EFCore 的实体特性:
本功能可实现与其他 ORM 使用一套 Attribute避免维护两份实体特性的烦恼
> v1.4.0+ 已自动识别 EFCore 实体特性 Key/Required/NotMapped/Table/Column
```csharp
fsql.Aop.ConfigEntity += (s, e) => {
var attr = e.EntityType.GetCustomAttributes(typeof(System.ComponentModel.DataAnnotations.Schema.TableAttribute), false).FirstOrDefault() as System.ComponentModel.DataAnnotations.Schema.TableAttribute;
var attr = e.EntityType.GetCustomAttributes(typeof(MyTableAttribute), false).FirstOrDefault() as MyTableAttribute;
if (attr != null)
e.ModifyResult.Name = attr.Name; //表名
};
fsql.Aop.ConfigEntityProperty += (s, e) => {
if (e.Property.GetCustomAttributes(typeof(System.ComponentModel.DataAnnotations.KeyAttribute), false).Any())
e.ModifyResult.IsPrimary = true; //主键
var attr = e.Property.GetCustomAttributes(typeof(MyColumnAttribute), false).FirstOrDefault() as MyColumnAttribute;
if (attr != null)
e.ModifyResult.Name = attr.Name; //字段名
};
