我如何申报"关键"在C＃中匿名类型的字段？ [英] How do I declare "Key" fields in C# anonymous types?

问题描述

在VB.NET我已经习惯了这样搞创建匿名类型时（ VB.NET匿名类型包括重点领域的概念）：

In VB.NET I'm used to doing things like this when creating anonymous types (VB.NET anonymous types include the notion of Key Fields):

Dim prod1 = New With {
    Key .Name = "paperclips",
    Key .Price = 1.29,
    .OnHand = 423
}

不过，我一直没能找到在C＃这样做的任何方式，因为它似乎不支持键关键字。

However, I haven't been able to find any way of doing this in C#, since it appears the Key keyword is not supported.

有没有办法在C＃中，表示在寻找平等？

Is there any way to indicate in C# that I only want to compare some of the fields in anonymous type when looking for equality?

推荐答案

有没有像在C＃。 在C＃中，匿名类型的所有属性是只读，并参与平等的比较。

There is nothing like that in C#. In C#, all properties of anonymous types are read-only and participate in equality comparisons.

如果你想要做这样的事情在C＃中，您将需要创建自己的（命名）类型。

If you want to do something like this in C#, you will need to create your own (named) type.
