Call C# dll function from C++/CLI

Question

I have a C# dll. The code is below:

public class Calculate
{
    public static  int GetResult(int arg1, int arg2)
    {
        return arg1 + a         


        

Answer 1

You must be using c++ CLI, otherwise you could not call DllImport. If that is the case you can just reference the c# dll.

In c++ CLI you can just do as follows:

using namespace Your::Namespace::Here;

#using <YourDll.dll>

YourManagedClass^ pInstance = gcnew YourManagedClass();

where 'YourManagedClass' is defined in the c# project with output assembly 'YourDll.dll'.

** EDIT ** Added your example.

This is how your example needs to look like in CLI (for clarity I am assuming that G etResult is not a static function, otherwise you would just call Calculate::GetResult(...)

private: System::Void CalculateResult(int arg1, int arg2)
{
    int rez=0;
    //Call C++ function from dll
    Calculate^ calculate= gcnew Calculate();
    rez=calculate->GetResult(arg1,arg2);   
}
