Get underlying entity object from entity framework proxy

Question

I have an entity by getting it from DbEntityEntry.Entity. This returns the Entity Framework proxy for the entity.

How do I access the underlying object

Answer 1

To get a JSON friendly object in EF Core I used this method:

T UnProxy(T efObject) where T : new()
{
    var type = efObject.GetType();

    if (type.Namespace == "Castle.Proxies")
    {
        var baseType = type.BaseType;
        var returnObject = new T();
        foreach (var property in baseType.GetProperties())
        {
            var propertyType = Nullable.GetUnderlyingType(property.PropertyType) ?? property.PropertyType;
            if (propertyType.Namespace == "System")
            {
                var value = property.GetValue(efObject);
                property.SetValue(returnObject, value);
            }
        }
        return returnObject;
    }

    return efObject;
}
