Associate attribute with code generated property in .net

Question

I wish to set an attribute on a public property in .NET, however I do not have access to the explicit property itself, as this has been code generated in another file.

Answer 1

Another option is to wrap the properties inside non-generated properties in the same class. Not ideal because you may end up having double properties but if you can make your generator make protected properties it'd be a pretty good approach.

Just had to deal with this problem: Entity Framework generates classes, I want to serialize them to JSON with simpler names.

// GENERATED BY EF
public partial class ti_Users
{
    public ti_Users()
    {
        this.ti_CardData = new HashSet();
        this.ti_Orders = new HashSet();
    }

    protected int userId { get; set; }
    protected string userName { get; set; }
    protected string userEmail { get; set; }
    protected string userPassHash { get; set; }
    protected Nullable userLastLogin { get; set; }
    protected string userLastIP { get; set; } 

    public virtual ICollection ti_CardData { get; set; }
    public virtual ICollection ti_Orders { get; set; }
}

and the add-on class:

[JsonObject(memberSerialization: MemberSerialization.OptIn)]
public partial class ti_Users
{
    [JsonProperty]
    public int UserId
    {
        get { return this.userId; }
        set { this.userId = value; }
    }

    [JsonProperty]
    public string Name
    {
        get { return this.userName; }
        set { this.userName = value; }
    }

    [JsonProperty]
    public string Email
    {
        get { return this.userEmail; }
        set { this.userEmail = value; }
    }

    [JsonProperty]
    public string PassHash
    {
        get { return this.userPassHash; }
        set { this.userPassHash = value; }
    }
}
