You can do half of it a bit more simply:

    foreach (PropertyMapping attrib in
        Attribute.GetCustomAttributes(i, typeof(PropertyMapping)))
    {
        ret += map.FieldName; // whatever you want this to do...
    }

btw; you should make a habit of ending attributes with the word Attribute. Even if this causes duplication (see [XmlAttributeAttribute]).

However - re serialization; that isn't always trivial. A deceptive amount of code goes into serialization frameworks like Json.NET etc. The normal approach might be to get a type-converter, but in many ways this is easier with a PropertyDescriptor:

    foreach (PropertyDescriptor prop in TypeDescriptor.GetProperties(obj))
    {
        Console.WriteLine("{0}={1}",
            prop.Name, prop.Converter.ConvertToInvariantString(
                prop.GetValue(obj)));
    }
