Conversion C#->CLI (snippets)

Thanks to everyone who has helped with some of my elementary questions about
C++/CLI equivalents to C#. I have a few more items that are giving me
headaches. All help is appreciated. What is the proper way to convert the
following?

1) data.ForEach(delegate(int num)
{ formatter->Serialize(stream, num); } );

(basically how are delegates implemented in C++/CLI)

2) return result as Dictionary<string, int>;

(how is this dynamic_cast performed?)

3) How do I pass an "array<int>^ myArray" into a method that takes an
integer array as an argument? Do I just pass the first element of the array,
like so: myArray[0]?

Thanks again for all the help

The anonymous method C# style for delegates does not exist in C++.

About passing the array, just pass "myArray": e.g., SomeMethod(myArray)

David,

OK, I tried your demo tool - it gave me the following for one of the
conversions.

generic<typename String^, typename int>
Dictionary^ MethodA()
{
Object^ result;
return dynamic_cast<Dictionary^>(result)<String^, int>;
}

This give me errors: syntax error for the '^' in the first line and
'unexpected tokens preceding {'. What am I doing wrong?

This is the original C# code, and yes it compiles:

Dictionary<string, int> MyMethod()
{
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream();

object result = formatter.Deserialize(stream);
return result as Dictionary<string, int>;
}

We've confirmed that the following two areas are converted incorrectly:
1. Generic method return types
2. "as" used with generic types

We are correcting this now - I'll post a follow-up when the new build is
available.

Thanks David.

So, without waiting for a new build, what would the correct conversion of
the code be? I am trying to convert this now, so if you could post the
correct answer it would be of great help.

The new build is available. The bug affecting generic method return types and
"as" used with generic types is fixed.

The C++/CLI equivalent for your sample is:

Dictionary<String^, int> ^MyMethod()
{
BinaryFormatter ^formatter = gcnew BinaryFormatter();
MemoryStream ^stream = gcnew MemoryStream();

Object ^result = formatter->Deserialize(stream);
return dynamic_cast<Dictionary<String^, int>^>(result);
}
