Hi!

I'm having problems with this, I need to cast an array of bytes from a VB6 ActiveX DLL reference method in a C# winform project.

the vb6 DLL would contain a method like

public function getArray() as byte()    dim arr    redim arr(0 to 100)    getArray = arrend fuction

and then in .NET

  myVBClass C = new myVBClass();  byte[] arr = (byte[])myVBClass.getArray();

But of course this isn't working.

How can I achieve this? Is it even possible? Should be done with strings?

Thanks in advance!

I found a way:

  Object[] myObj = myComClass.getArray();  for (int i=0; i < myObj.Lenght; i++)  {    Byte MyByte = Convert.ToByte(myObj);  }

A slightly terser way to express that would be

byte[] arr = Array.ConvertAll(myVBClass.getArray(), Convert.ToByte);
