通过COM互操作将字节数组从C＃返回到VBScript

我有C＃方法，该方法返回一个我希望能够从VBScript访问的字节数组。或多或少：

I have C# method that returns a byte array I want to be able to access from VBScript. More or less:

namespace ClassLibrary7
{
    [ClassInterface(ClassInterfaceType.AutoDual)]
    [Guid("63A77D29-DB8C-4733-91B6-3CC9C2D1340E")]
    [ComVisible(true)]
    public class Class1
    {
        public void Create(
            out byte[] BinaryData
            )
        {
            // do some work and return BinaryData
            BinaryData = new byte[] { 1, 2, 3, 4 };
        }
     }
 }

和vbscript看起来像：

and the vbscript to look like:

dim o
dim b

set o = wscript.CreateObject("ClassLibrary7.Class1")

o.Create b

MsgBox ubound(b)

我迷路了。 Google不想合作...我希望这里有人可以提供帮助！

I'm lost. Google doesn't want to cooperate... and I'm hoping someone here can help!
