Question

是否可以将Python COM服务器导入Ironpython程序？

我的意思是Python类脚本（* .py），它使用win32com.server.register.UseCommandLine()注册为COM服务器，然后使用Activator.CreateInstance(Type.GetTypeFromProgID('python.progid'))从Ironpython调用。

我已经尝试了好几次但总是失败了。从回溯中，它显示Ironpython尝试执行脚本而不是导入它，这当然失败了。据我所知，作为COM对象，脚本应该由Python运行，而不是Ironpython。 Ironpython将使用输出。但是，使用相同的Activator.CreateInstance（）命令，它可以从C＃导入COM服务器。在C＃中，我能够从COM类中的方法调用，传递和检索值。

这是py脚本：

    class TestCom:
        _reg_progid_ =  "TestCom.DisplayText"
        _reg_clsid_ = "{B02B1819-2954-4E47-8E19-570652B38DF2}"

        def __init__(self):
            self.DisplayThis = "Hello from python world"
            self.aText = ""

        def DeliverText(self, aText):
            "say hello"
            if aText <> "": self.DisplayThis = aText
            return self.DisplayThis

    if __name__=='__main__':
        import sys
        sys.path.append(r'C:\Python27')
        sys.path.append(r'C:\Python27\Lib')
        sys.path.append(r'C:\Python27\Lib\site-Packages')
        print "Registering COM server..."
        import win32com.server.register
        win32com.server.register.UseCommandLine(TestCom)

这是来自Ironpython的命令（带错误）：

    >>>from System import Type, Activator
    >>>o = Activator.CreateInstance(Type.GetTypeFromProgID('TestCom.DisplayText'))
    pythoncom error: PythonCOM Server - The 'win32com.server.policy' module could not be loaded.

BTW，我是IronPython和Python的新手。我使用2.7版本。

感谢您的帮助。
