How to print out all the base type of an object?

Question

I have an object, I would like to print out all its parent type up to the Object? How to do that?

Answer 1

If you're only interested in the class hierarchy:

Type type = obj.GetType();
while (type != null)
{
    Console.WriteLine(type.Name);
    type = type.BaseType;
}

Answer 2

var t = obj.GetType();

while (t != null)
{
    Console.WriteLine(t.Name);
    t = t.BaseType;
}
