Casting object to int throws InvalidCastException in C#

Question

I have this method:

private static Dossier PrepareDossier(List> rawDossier)
{
    return new Dossier((int)rawDossier[0][0]);
}
         


        

Answer 1

I would guess this is because the object in your list is not an int.

Convert.ToInt32 will convert other non-int types so works.

Check what is being passed in to the method.
