Like LBushskin said, you do not have to do this. This is not the fastest way! Buy if you want, try this:
public static List<PropertyInfo> GetDifferences(Employee test1, Employee test2)
{
List<PropertyInfo> differences = new List<PropertyInfo>();
foreach (PropertyInfo property in test1.GetType().GetProperties())
{
object value1 = property.GetValue(test1, null);
object value2 = property.GetValue(test2, null);
if (!value1.Equals(value2))
{
differences.Add(property);
}
}
return differences;
}
