有没有办法来添加属性的LINQ查询结果比下面？

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
                };

我想这样做，没有列出所有我的对象的当前属性。有许多属性，我不希望有更新此code每当我可能改变我的课。

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.

我仍然在学习与LINQ和我AP preciate你的建议。

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

推荐答案

与部分类添加它：

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

然后你可以，你所创建的对象后，分配给它。

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