Generic XML Node to Class

Hello, I need to interface with WSUS (using dotnet 8) using ApiRemoting (SOAP), in some functions, it returns a List<Object> (it's intended afaik in the WSDL file). Is there a way to deserialize the generic type to a specific one without resorting to manual casting and enumerating one by one the list ? (with reflection for exemple) exemple from the wsdl : https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-wsusar/c162f3b0-61bb-4134-815c-f089962f2e30 Thanks in advance ! 🙂

if you have a wsdl you can directly generate a client with visual studio

It's already generated using dotnet-svcutil, but still doesn't help the GenericReadableRow (which in the end is a List<Object>) which I need to manually unmarshall sadly

so it's a useless wsdl 😐 how many types do you have to deserialize

around 10 found a way :

c#
internal static class MyExtensions
{
    internal static T Cast<T>(this GenericReadableRow r) where T : new()
    {
            var result = new T();

            foreach (var prop in typeof(T).GetProperties())
            {
                if (prop.GetCustomAttribute<ValueAttribute>() is ValueAttribute attr)
                {
                    prop.SetValue(result, r.Values[attr.Index]);
                }
            }

            return result;
    }
}

c#
internal static class MyExtensions
{
    internal static T Cast<T>(this GenericReadableRow r) where T : new()
    {
            var result = new T();

            foreach (var prop in typeof(T).GetProperties())
            {
                if (prop.GetCustomAttribute<ValueAttribute>() is ValueAttribute attr)
                {
                    prop.SetValue(result, r.Values[attr.Index]);
                }
            }

            return result;
    }
}

I have still a GenericReadableRow, but I can cast it dynamicaly using attributes to make it "generic"

i would move the logic into a mapper class or inside a static Create method of the type itself so that there is more error checking and explicitness
