如何从.NET中使用VB6 DLL？

Question

How to consume a VB6 DLL from .net?

The dll has a method called rfc that returns an array, and has a parameter that is a vector of integers. How to make the call to this dll?

Please give examples.

var cls = new MyDllVB6.MyClassInVB6();
/*?Array?*/ = cls.MyFunctionInClass( /*?Vector of integer?*/);

Answer 1

VB6 dll是普通的COM dll，所以只需将它添加到项目引用即可，.NET COM互操作将为您完成剩下的工作。

Answer 2

int[] vectorOfIntegers = new int[5];
vectorOfIntegers[0] = 123;
vectorOfIntegers[1] = 456;
.
:
int[] outputArray = cls.MyFunctionInClass(vectorOfIntegers);
