Multiply two fields in Linq

Question

Is there any option for multiply two fields in LINQ

public class details
{
 public int qty { get; set; }
 public decimal unitprice{ get; set; }
 public decimal total{ get; set; }
}

select new details
{
 qty =x.qty ,
 unitprice= x.unitprice,
 total= x.qty*x.unitprice,
}

If not pls give any proper code

Answer 1

You probably want a Select() clause:

someLinqQuery.Select(detailsObject => new details
{
    qty = detailsObject.qty,
    unitprice = detailsObject.unitprice,
    total = detailsObject.qty * detailsObject.unitprice
}

But it looks like you need a get only property like this:

public class details
{
    public int qty { get; set; }
    public decimal unitprice { get; set; }
    public decimal total =>  qty * unitprice;
}
