Property setter type other value set to property?

It is possible for the type returning by a property's get accessor to be different from the type used by the set accessor?

private string[] artists;
public string[] Artists
{
    get { return artists[0]; } //heree getter return string than string[]
    set { artists = value; OnPropertyChanged("Artist"); }
}

No, this won't work.

You could add another property, and include it in the ONPC:

public string Artist
{
    get { return artists[0]; }
}

public string[] Artists
{
    // get { return artists; }   // get string[] is optional
    set { artists = value; OnPropertyChanged("Artist"); OnPropertyChanged("Artists");}
}

Provide a sample of intended use with some context and you might get a better answer.

No, not possible. It is plain to see that your code is illegal, because your get accessor does not fulfil it's obligation to return a string[]

// you define the Artists property as a string[],
// therefore the get accessor must return a string[]
public string[] Artists
{
    // you are returning only a string
    get { return artists[0]; }

Why should this be possible. If you declare the return type then this HAS to be returned.

No this is not possible. You have to create another property to return another type.
