How to create a model Class with fixed prefix

Question

I have a dotnet core application. I added model class everytime with fixed prefix. It goes very lengthy and unhandled way. Is there any better way to handle this?

public class Category
{
    public string? gmailIN{ get; set; }

    public string? aolIN{ get; set; }
    public string? outlookIN{ get; set; }
    public string? yahooIN{ get; set; }
    public string? hotmailIN{ get; set; }
    public string? ZohoIN; set; }

    public string? aolAU{ get; set; }
    public string? outlookAU{ get; set; }
    public string? yahooAU{ get; set; }
    public string? hotmailAU{ get; set; }
    public string? ZohoAU{get; set; }
    public string? gmailAU{ get; set; }

    public string? aolUK{ get; set; }
    public string? outlookUK{ get; set; }
    public string? yahooUK{ get; set; }
    public string? hotmailUK{ get; set; }
    public string? ZohoUK{get; set; }
    public string? gmailUK{ get; set; }
        
    public string? gmailUS{ get; set; }
    public string? aolUS{ get; set; }
    public string? outlookUS{ get; set; }
    public string? yahooUS{ get; set; }
    public string? hotmailUS{ get; set; }
    public string? ZohoU{get; set; }
}

Prefix is always the same. Is there any better way to add variables instead of adding above way?

Do all these properties need to remain in the same class? Does it even need to be properties? Is there a common pattern for determining a property value based on its name? How are you defining "better way"? — gunr2171, Aug 29 '22 at 14:39

If possible split Category and Country.

You can create a class like:

public class Category
{
   public string? gmail{ get; set; }    
   public string? aol{ get; set; }
   public string? outlook{ get; set; }
   public string? yahoo{ get; set; }
   public string? hotmail{ get; set; }
   public string? Zoho{get; set; }
}

and then one Dictionary for mapping it with country

public Dictionary<string,Category> Categories;

or add the Country property inside the Category class itself.
