You can use this Extension method.

public static class Extensions
{
    public static object GetFieldValue(this object instance, string fieldName)
    {
        const BindingFlags bindFlags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static;
        var field = instance.GetType().GetField(fieldName, bindFlags);
        return field == null ? null : field.GetValue(instance);
    }
}
