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

问题描述

让我们说我有下面这段代码：

Let's say I have the following piece of code:

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

基本上，我期望在问：匿名类型与序列命名属性
中文别名而非 SomeConst 。
我怎样才能实现这样的行为？

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

您不能这样做。匿名类型的属性名称必须在编译时是已知的。 ？到底为什么你需要做的。

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?

您可以通过创建一个字典，而不是匿名对象序列达到类似的效果：

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 }
});
