Question

What i currently use

public static void MapObjectPropertyValues(object e1, object e2)
    {
        foreach (var p in e1.GetType().GetProperties())
        {
            if (e2.GetType().GetProperty(p.Name) != null)
            {
                p.SetValue(e1, e2.GetType().GetProperty(p.Name).GetValue(e2, null), null);
            }   

        }
    }

I want to pass a third parameter, a generic list of types that i want to exclude from the mapping. For example strings and booleans. And check if p is of a type in the list. Any help is appreciated, thanks!

You could use the p.PropertyType property to exclude assignment if the types match exactly.

public static void MapObjectPropertyValues(object e1,
                  object e2,
                  IEnumerable<Type> excludedTypes)
{
    foreach (var p in e1.GetType().GetProperties())
    {
        if (e2.GetType().GetProperty(p.Name) != null && 
        // next line added
        !(excludedTypes.Contains(p.PropertyType)))
        {
            p.SetValue(e1, e2.GetType().GetProperty(p.Name).GetValue(e2, null), null);
        }
     }
}
