排除要迁移的属性 [英] Exclude properties for migrations

问题描述

我的模型上具有属性，我不想在迁移后在表中生成字段.

I have properties on my model that I don't want to generate fields in the tables after a migration.

是否可以排除 properties 用于Entity Framework Core迁移?

Is it possible to exclude properties for Entity Framework Core migrations?

在我的 DbContext 上是否有模型的属性或某些Fluent API方法?

Is there an attribute for the model or some Fluent API method on my DbContext for this?

推荐答案

您应该能够在属性上方将 [NotMapped] 指定为数据注释.

You should be able to specify [NotMapped] as a data annotation above the property.

例如如果您希望模型中包含 FirstName 和 LastName 的 FullName ，则可以执行以下操作:

E.g. if you wanted to have FullName in your model which consisted of FirstName and LastName you would do:

public string FirstName { get; set; }
public string LastName { get; set; }

[NotMapped]
public string FullName { get;set };
