Ruby WIN32OLE_RECORD類用法及代碼示例

WIN32OLE_RECORD 對象代表VT_RECORD OLE 變體。如果調用 OLE 方法的結果值，Win32OLE 返回 WIN32OLE_RECORD 對象。

如果 VB.NET ComServer 項目中的 COM 服務器如下：

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure Book
        <MarshalAs(UnmanagedType.BStr)> _
        Public title As String
        Public cost As Integer
    End Structure
    Public Function getBook() As Book
        Dim book As New Book
        book.title = "The Ruby Book"
        book.cost = 20
        Return book
    End Function
End Class

然後，您可以從以下 Ruby 腳本中檢索 getBook 返回值：

require 'win32ole'
obj = WIN32OLE.new('ComServer.ComClass')
book = obj.getBook
book.class # => WIN32OLE_RECORD
book.title # => "The Ruby Book"
book.cost  # => 20
