You also can use the ? option, make a list of the following type:

public class MyClass
{
    public string? x {get;set;}
    public double? y {get;set;}
}

This way you can select if none, one or both can have a value.

Or if you don't like the HasValue/Value functions:

public class MyClass
{
    public enum EType { String, Double };

    EType TypeFilled {get; private set }

    string _x;
    public string X { get { return _x; }; set { _x = value; TypeFilled = EType.String; }
    double y;
    public double y { get { return _y; }; set { _y = value; TypeFilled = EType.Double; }
}

This way the typeFilled property decides what is filled. You could add validation to prevent being set twice etc.
