Question

If I have a complex object, can I inherit from it and remove or ignore certain properties?

If you don’t care why I want to do this, feel free to just submit an answer.

If you do care, you can read this question. To summarize it, I have an object that has a single property that is not serializable, and I want to serialize the entire object. The object in question is System.Exception

To get around the problem I wanted to simply create my own JsonException object, inherit all the lovely properties of the base (System.Exception) except remove (or empty) the ugly duckling (Exception.TargetSite).

Something like:

public class MyException : Exception
{
    // Note this is not actually possible
    //      just demonstrating what I thought to do in theory
    public override System.Reflection.MethodBase TargetSite
    {
        get
        {
            return null;
        }
    }

    public MyException(string message)
        : base()
    {
    }
}

Also please keep in mind I am stuck with .NET 2.0 and really don’t want to use custom serializers (like Json.NET) if I don’t have to.

Answer 1

Did you try it without overriding the TargetSite property? I was able to do it (but not in 2.0, so I’m not sure if it will work for you like this

public class MyException : Exception
{
    public new System.Reflection.MethodBase TargetSite
    {
        get { return null; }
    }

    public MyException() : base()
    {

    }
}
