Thread: ToArray and Type Casting

I have an ArrayList and a string which I want to find chars of ArrayList in it. My ArrayList is named punctuations.

Code:

      tatic System::Collections::ArrayList ^punctuations =  gcnew System::Collections::ArrayList;
      punctuations->Add('/');
      punctuations->Add('\n');
      punctuations->Add(' ');
      punctuations->Add('\t');
      punctuations->Add('\"');
      punctuations->Add('\'');
      
      array<wchar_t>^myArr =safe_cast<array<wchar_t>^>(punctuations->ToArray(wchar_t::typeid));

      int firstToken = text->IndexOfAny(myArr, startpos);

It fails to cast and says at least one source element can't be cast to dest array type.
But don't know why...

You have objects of type "char" and you try to get an array of type wchar_t. Maybe it's easier to insert wchar_t characters from the start. You could also use a generic list so you are typesafe. Or you could use an array without using an arraylist in between.

Why do you use C++/CLI if I may ask? If you want .NET, C# is better suited, interfacing between legacy C++ code and a C# application is the only valid excuse for using C++/CLI. Or Masochism. C++/CLI combines the readability of C++ and the speed of .NET ...

Thread in MSDN...

lol, Masochism it seems to be. The reason I am using it is that once I decided to fully learn C++/CLI. As a result I started a project to practice it. Now I am back to that project.

Thanks

That sounds like hitting yourself with a hammer just out of curiosity and to learn how it feels. If you don't know the .NET Framework yet, try to learn C#, it's way easier and C++/CLI is just 3 additional keywords once you know .NET and C++.

I practiced C#, VB.net and C++/CLI and I have an acceptable knowledge about .NET now (at least from my own view point). But I decided to focus on C++.

I am also thinking about F# right now. Do you know it?
