Question

I am getting familiar with c++/cli. I am writing a function called Locate with a class called Locator. The function that takes input a dictionary of strings.

Dictionary<String^, array< Byte >^>^ Locate(Dictionary<String^, String^>^ imgParms) 

I am trying to call it in the main function by doing this:

Locator r;

Dictionary<String^,String^> myDictionary = 
               gcnew Dictionary<String^,String^>();

r.Locate(myDictionary);

but I am getting this error

error C3073: 'System::Collections::Generic::Dictionary<TKey,TValue>' : ref class does        
not have a user-defined copy constructor with
          [
              TKey=System::String ^,
              TValue=System::String ^
          ]

Any help would be appreciated.

Answer 1

Dictionary<String^,String^> myDictionary = 
               gcnew Dictionary<String^,String^>();

Should be

Dictionary<String^,String^>^ myDictionary = 
               gcnew Dictionary<String^,String^>();

the ^ symbol can be thought of as a type modifier like * do gcnew is returning you ax^ to type x
