如何从一个模型类到另一个模型类调用属性值？

Question

I have an attribute called ServiceName in my Service.cs class, and I want the same value to show in another class called Booking.cs without me having to enter it again.

public class Service
{
    public string ServiceName { get; set; }
}



public class Booking
{    
    [DisplayName("Service Chosen")]
    public string ServiceName { get; set; }    
}

Answer 1

So you must communicate between two class so you must use something like Prism EventAggregator With this you can send value if its change like

public string ServiceName
{
    get { return _serviceName; }
    set
    {
        _serviceName = value;
        EventAggregator.GetEvent<eventname>().Publish(_serviceName);
    }
}

and subscribe using EventAggregator.GetEvent<eventname>().Subscribe(YourSubscribeMethod);

you can read about it here https://prismlibrary.github.io/docs/event-aggregator.html
