c＃中带变量的动态对象

Question

是否可以构建属性名称设置为变量值的动态对象？

例如，这似乎是标准......

dynamic elem = new Object();
elem.Name = "myName";

但是如何实现呢？...

string fn = "FirstName";
string ln = "LastName";
dynamic elem = new Object();
elem.fn = "John";
elem.ln = "Doe";

因为我可以调用像...这样的属性。

string fn = elem.FirstName;

ExpandoObject还实现了IDictionary<string, object>，这意味着您可以使用字符串键添加属性。

dynamic person = new ExpandoObject();

person.FirstName = "Alex";
var ln = "lastname";

(person as IDictionary<string, Object>)[ln] = "KeySmith";
