C# : Out of Memory exception

c# .net out-of-memory

Today my application threw an OutOfMemoryException. To me this was always almost impossible since I have 4GB RAM and a lot of virtual memory too. The error happened when I tried to add an existing collection to a new list.

List<Vehicle> vList = new List<Vehicle>(selectedVehicles);

To my understanding there isn't much memory allocated here since the vehicles my new list should contain already exist inside the memory. I have to admit Vehicle is a very complex class and I tried to add about 50.000 items to the new list at once. But since all Vehicles in the application come from a database that is only 200MB in size, I have no idea what may cause an OutOfMemoryException at this point.

3 years old topic, but I found another working solution. If you're sure you have enough free memory, running 64 bit OS and still getting exceptions, go to Project properties -> Build tab and be sure to set x64 as a Platform target.
