                try
                {
                    return (T)Convert.ChangeType(obj, typeof(T));
                }
                catch(InvalidCastException)
                {
                    continue;
                }

                try
                {
                    return (T)Convert.ChangeType(obj, typeof(T));
                }
                catch(InvalidCastException)
                {
                    continue;
                }

well, that catch will catch invalid cast exception, so the problem is something else, or you didn't re-build

i am using mono but i don't know if this interferes with the code running because it prints out that there was an exception

phaseshift•15mo ago

look at the call stack then

Angius•15mo ago

As a side note... why Mono...?

annoyingb•15mo ago

what else? coreclr made no sense to me

Angius•15mo ago

How did it not make sense? .NET is the cross-platform runtime There's zero reason to use Mono for any new project Unless you're trying to do some weird shit like running WPF on Linux

annoyingb•15mo ago

the docs told me not to use some files but to run the code i needed the files and some files that i needed weren't mentioned. also, isn't coreclr still in development?

Angius•15mo ago

Uh, no? Hasn't been for years Hell, it's no longer even named .NET Core Now it's just .NET Has been this way for 3 major versions already

annoyingb•15mo ago

oh well are there any docs that are simple and make sense?

Angius•15mo ago

Angius•15mo ago

What do you mean?

annoyingb•15mo ago

so i can use c++ with c#

it's too confusing i'd rather use mono

Angius•15mo ago

It started being confusing the moment you said you want to use C++ with C# lmao

annoyingb•15mo ago

yeah but mono is really simple to get to work unlike the coreclr which looks like writing c# code in c++

Angius•15mo ago

Just write C# code and skip the C++ part

annoyingb•15mo ago

what do you mean?

Angius•15mo ago

Why do you need to use C++ with C#?

phaseshift•15mo ago

Why are you talking about c++ in the first place? Just use c# with ".net"

Angius•15mo ago

What do you need it for that you can't do with C#?

annoyingb•15mo ago

i want to learn how to use c# and c++ together

Angius•15mo ago

Why

annoyingb•15mo ago

because i want to learn

phaseshift•15mo ago

then learn one thing first

annoyingb•15mo ago

pinvoke didn't go too well :\

Angius•15mo ago

With an obsolete framework Lemme go learn cave painting right quick Will make me more desireable on the job market

annoyingb•15mo ago

but that is not what i am trying to do i'm not trying to get a job i just want to learn...

Angius•15mo ago

So, I assume you already know C++ and C# well?

annoyingb•15mo ago

yeah

Angius•15mo ago

You not knowing about .NET makes me doubt that a little, but aight, go ahead and create your chimera of a project

annoyingb•15mo ago

jcotton42•15mo ago

@youdontknowwhoiam what specially does Mono do better wrt C++ interop than the CoreCLR? *specifically

Jimmacle•15mo ago

i think he's talking about hosting the CLR within a C++ application

annoyingb•15mo ago

yeah i am
