Question

This is my class, for example :

public class Point
{
    public string Min { get; set; }
    public string Max { get; set; }

    public Point()
    {

    }
}

and I’m building dynamic objects through linq to xml :

var list = xDoc.Descendants("item").Select(item => new
{
    NewPoint = new Point()
});

Now, I’d like to associate for each NewPoint the value item.Min and item.Max.

Such as NewPoint.Min = item.Min and NewPoint.Max = item.Max, without creating a Class constructor with 2 param in the method.

Is it possible? Hope the question is clear…

Answer 1

You can use an object initializer:

Point = new Point() { Min = n["min"], Max = n["max"] }

(or however you get your values out of n)

Alternatively, you can put a whole code block in your Select:

.Select(n => {
    var point = new Point();
    point.Min = n["min"];
    point.Max = n["max"];
    return new { Point = point };
});

Also note: unless you’re selecting other things as well, you don’t need

n => new { Point = new Point() }

You can just use n => new Point() and end up with an IEnumerable<Point> rather than an IEnumerable<AnonymousClassContainingPoint>.
