Answer 1

List<Type> types = (from item in comboBox.Items select item.GetType()).Distinct();

This yields a list of all the types that appear in your combo box items.

If you just want to test whether one specific type appears in your list, you can do the following:

bool containsStrings = comboBox.Items.OfType<string>.Any()
bool containsDependencyObjects = comboBox.Items.OfType<DependencyObject>.Any()
