LINQ - order by distance (calculated value)

Question

What I would like is to loop through each item of a List in ascending order of distance (so the nearest targets are used first).

foreach (ShipCompartment enemyComp in enemy.ListOfCompartments.OrderBy(...))

The problem is that the distance is not a member of the class. Therefore I can't use:

foreach (ShipCompartment enemyComp in enemy.ListOfCompartments
    .OrderBy(c => c.Distance))

The code used to calculate distance is:

// Get distance between player and enemy compartments
float distanceToTarget = Vector2.Distance(playerComp.Position,
    enemyComp.Position);

How can I incorporate the calculation into OrderBy()? I've looked over here but it only returns the nearest Vector2.

Many thanks for your assistance.

Answer 1

The simple option would be to move the function call to the OrderBy call, so something like:

foreach (ShipCompartment enemyComp in enemy.ListOfCompartments.OrderBy(c => Vector2.Distance(playerComp.Position, c.Position)))
