C# Using Reflection to copy base class properties

c#, copy, reflection

Solution

Try this:

public void Update(MyObject o)
{
    MyObject copyObject = ...
    Type type = o.GetType();
    while (type != null)
    {
        UpdateForType(type, o, copyObject);
        type = type.BaseType;
    }
}

private static void UpdateForType(Type type, MyObject source, MyObject destination)
{
    FieldInfo[] myObjectFields = type.GetFields(
        BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);

    foreach (FieldInfo fi in myObjectFields)
    {
        fi.SetValue(destination, fi.GetValue(source));
    }
}

Problem

I would like to update all properties from MyObject to another using Reflection. The problem I am coming into is that the particular object is inherited from a base class and those base class property values are not updated. The below code copies over top level property values. ``` public void Update(MyObject o) { MyObject copyObject = ... FieldInfo[] myObjectFields = o.GetType().GetFields( BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance); foreach (FieldInfo fi in myObjectFields) { fi.SetValue(copyObject, fi.GetValue(o)); } } ``` I was looking to see if there were any more BindingFlags attributes I could use to help but to no avail.
