Question

I have a dictionary myResult:

Dictionary<String^,array< Byte >^>^ myResult = gcnew Dictionary<String^,array< Byte >^>(); 

I am declaring

array <Byte^>^ a;

and then I am adding a to a key of the dictionary

myResult->Add("OVERVIEW",a);

I am getting an error

error C2664: 'System::Collections::Generic::Dictionary<TKey,TValue>::Add' : 
cannot       convert parameter 2 from 'cli::array<Type> ^' to 'cli::array<Type> ^'

1>              TValue=cli::array<unsigned char> ^
1>          ]
1>          and
1>          [
1>              Type=System::Byte ^
1>          ]
1>          and
1>          [
1>              Type=unsigned char
1>          ]

Any help is appreciated since I am still not very familiar with c++/cli;

Answer 1

Dictionary<String^,array< Byte >^>^
                          ^ Uppercase B

array <byte^>^ a;
       ^ Lowercase B

Byte^ and byte^ name different types (actually, I am somewhat surprised that the latter compiles, though I am not a C++/CLI expert). The former is a tracking handle to a System::Byte. The latter is an unsigned char (apparently the compiler is dropping the hat, I presume it does so because it is not a CLI type, making it ineligible to wear hats).
