Anybody know what the max number of items in a List is?

How do I increase that size? Or is there a collection that takes infinite items? (as much as would fit in me

Answer 1

On a x64 Machine, using .Net Framework 4 (Not the Client Profile), compiling for Any CPU in Release mode, I could chew up all the available memory. My process is now 5.3GB and I've consumed all available memory (8GB) on my PC. It's actually a Server 2008 R2 x64.
I used a custom Collection class based on CollectionBase to store 61,910,847 instances of the following class:

public class AbbreviatedForDrawRecord {
    public int DrawId { get; set; }
    public long Member_Id { get; set; }
    public string FactorySerial { get; set; }

    public AbbreviatedForDrawRecord() {

    }

    public AbbreviatedForDrawRecord(int drawId, long memberId, string factorySerial) {
        this.DrawId = drawId;
        this.Member_Id = memberId;
        this.FactorySerial = factorySerial;
    }
}
