Map multiple properties to a single

[danielwinkler]

Hi,

is is possible to combine multiple properties into a single?
A classic example would be

public class User
{
    public Guid Id { get; }
    public string Firstname { get; }
    public string Lastname { get; }
}

public class UserDto
{
    public Guid Id { get; }
    public string Name { get; } // Firstname + " " + Lastname
}

Thank you for any help

You can use before/after map for this.

How would I apply before or after in an IQueryable projection? Trying to add an IsDeletable property something like this.

IsDeletable = a.Children.Any() == false && a.StepChildren.Any() == false

Where Children and StepChildren are public ICollection

This is not possible in an IQueryable projection.

Thanks @latonz ,

that's how i solved it for now.
for the case with a required property:

public class User
{
    public Guid Id { get; }
    public string Firstname { get; }
    public string Lastname { get; }
}

public class UserDto
{
    public Guid Id { get; }
    public **required** string Name { get; } // Firstname + " " + Lastname
}

there will be a compile time error though, which needs to be worked around by assigning something and overwriting it.
Or is there a nicer way than that?

It should be possible using an object factory, however with an object factory all required properties need to be initialized in the object factory. There is currently no other solution...
