设置匿名类型属性名称 [英] Setting anonymous type property name

问题描述

假设我有以下代码:

string SomeConst = "OtherName";
var persons = GetPersons(); //returns list of Person
var q = persons.Select(p => 
new
{
    SomeConst = p.Name
});

基本上我希望在 q 序列中具有该属性的匿名类型名为 OtherName 而不是 SomeConst.我怎样才能实现这种行为?

Basically I'd expect to have in q sequence of anonymous type with the property named OtherName and not SomeConst. How can I achieve such a behaviour?

推荐答案

你不能那样做.匿名类型的属性名称必须在编译时已知.为什么你需要这样做?

You can't do that. The names of the properties of an anonymous type must be known at compile time. Why exactly do you need to do that?

您可以通过创建字典序列而不是匿名对象来实现类似的效果:

You could achieve a similar effect by creating a sequence of dictionaries instead of anonymous objects:

string SomeConst = "OtherName";
var persons = GetPersons(); //returns list of Person
var q = persons.Select(p => 
new Dictionary<string, string>
{
    { SomeConst, p.Name }
});
