How to return a default value for a property?

I have the following Graphql type class including the POCO class: Order.cs.

Here I want to set the default value of each field. For example for Name I want to return "No Name" in case there is no value returned for it. In case of Created, I want to return today's date by default.

public class OrderType : ObjectGraphType<Order>
{
    public OrderType(ICustomerService customers)
    {
        Field(o => o.Id);
        Field(o => o.Name);
        Field(o => o.Description);
        Field(o => o.Created);
    }
}

public class Order
{
    public Order(string name, string description, DateTime created, string Id)
    {
        Name = name;
        Description = description;
        Created = created;
        this.Id = Id;
    }

    public string Name { get; set; }

    public string Description { get; set; }

    public DateTime Created { get; private set; }

    public string Id { get; private set; }
}

Can anyone help me to fix this issue?

If you are using C# 6+, it has added the ability to assign a default value to auto-properties. So you can simply write something like this:

public string Name { get; set; } = "No Name";
public DateTime Created { get; private set; } = DateTime.Today;

This will set the default value of the Name property to No Name and the Created property to today's date, as you wanted.
