            MessageBox.Show("Hello world.");
            return "Hello from CSetup object";
        }

当我使用regasm /codebase /tlb /verbose Whatever.dll时，我得到了这样的反馈：

Microsoft (R) .NET Framework Assembly Registration Utility 4.0.30319.1
Copyright (C) Microsoft Corporation 1998-2004.  All rights reserved.

Types registered successfully
Type 'N' exported.
Type 'N' exported.
Assembly exported to 'C:\Users\Whoever\Whatever.tlb', and the type lib
rary was registered successfully

除了不知道Type'N'导出的含义之外，哪个很好，但程序集确实在HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \中显示为“Whatever.CSetup”

如果我启动浏览器到包含JavaScript（下面转载）的网站，该网站尚未识别出有问题调用的.NET程序集方法，我可以看到，在MSIE菜单工具！Internet选项！程序！管理添加-ons！工具栏和扩展，“Whatever.CSetup”与“名称”列中的其他几个加载项一起显示，“状态”列将其报告为“已启用”。（虽然它的“加载时间”和“导航时间”列没有显示任何内容 - 但是“发送到蓝牙设备”或其他一些设备都没有。）

    }
    catch(Err)
    {
        alert(Err.description);
    }
}   
</script>
 </body>
</html>

当我进入页面时，我得到“无法获取属性Whatever.CSetup'的值：对象为null或未定义”

我知道这一点：如果我通过更改JavaScript中的CLSID进行测试，那么转到该页面根本不会触发任何内容。如果我将其更改回来，我会收到该错误消息。
我无法确定我在<OBJECT id="Whatever.CSetup" name=”Whatever.CSetup" classid="clsid:81F44339-C03D-444F-95AD-3E86CF8FA514" VIEWASTEXT codebase="Whatever.CSetup"></OBJECT>中提供的内容，除了冒险我在CLSID字段中拥有正确的值。还有其他的，“id”或“name”或“codebase”，我不知道。
我不知道我是否正确地在js底部附近调用汇编类方法。

类似于此的JavaScript被认为能够调用.NET汇编方法。有三个网站确认这是可能的：

感谢您的帮助。

这个程序集看起来很容JavaScript无法找到它
