LINQ - 向结果添加属性

问题描述

有没有办法给 Linq 查询结果的对象添加属性而不是下面的内容?

Is there a way to add a property to the objects of a Linq query result other than the following?

var query = from x in db.Courses
                select new
                {
                    x.OldProperty1,
                    x.OldProperty2,
                    x.OldProperty3,
                    NewProperty = true
                };

我想在不列出对象的所有当前属性的情况下执行此操作.有很多属性，我不想每次更改类时都必须更新此代码.

I want to do this without listing out all of the current properties of my object. There are many properties, and I don't want to have to update this code whenever I may change my class.

我仍在学习 LINQ，感谢您的建议.

I am still learning with LINQ and I appreciate your suggestions.

推荐答案

添加部分类:

public partial class Courses
{
    public String NewProperty { get; set; }
}

然后您可以在创建对象后对其进行分配.

Then you can assign it after you've created the object.
