How to get a displayname attribute when assign values to a property

Question

I have the following property class

public class UserModel{
    public string Name {get;set;}
    [DisplayName="Document Name"]
    public string DocumentName {get;set;}
    [DisplayName="Terms Usage"]
    public string TermsUsage {get;set;}
}

i then call this method when i am assigning values to it as

var item=new List<UserModel>();
foreach(var i in records)
{
    //some code happens
    
    item.Add(new UserModel
    {
        Name = i.FirstName,
        
        DocumentName = i.DocumentName, //i would like to return the item with the display name
        TermsUsage = i.TermsUsage
    }); 
}

return item;

so when the item is returned it still has the userModel "DocumentName" and "TermsUsage" how can i get the display name to be returned when returning the item as "Document Name" and "Terms Usage" so that i could make use of them in other parts of code?
