有关COM Interop（COM互操作技术）的介绍

COM Interop 是一种让 .NET Framework 的程序能够和 COM 的程序相互操作的一种桥接技术，是 .NET Framework 互通性的一环，COM Interop 可以让 .NET Framework 的程序使用 COM 组件，也可以让 COM 程序使用 .NET Framework 的组件，例如可以使用 .NET Framework 开发应用程序给 ASP 的应用程序使用，或是把旧有的 ActiveX 组件让 .NET Framework 的程序调用。

COM Interop 的服务是由 System.Runtime.InteropServices 名字空间中的类别来提供，其中最重要的是 Marshal 类别，它提供了 managed code 和 unmanaged code 之间的资料格式与指针转换，对于互通性来说具有相当大的帮助。

在 .NET Framework SDK 中提供了可由 COM 类型库中产生 .NET 组件 的 tlbimp.exe，以及让 .NET 组件产生类型库的regasm.exe两个工具程序。


组件对象模型 （COM） 允许对象向其他组件和宿主应用程序公开其功能。虽然 COM 对象多年来一直是 Windows 编程的基础，但为公共语言运行时 （CLR） 设计的应用程序具有许多优点。

.NET Framework 应用程序最终将取代那些使用 COM 开发的应用程序。在此之前，您可能必须使用 Visual Studio 使用或创建 COM 对象。与 COM 或 COM互操作的互操作性使您能够使用现有的 COM 对象，同时按照自己的节奏过渡到 .NET Framework。

打开我们的注册表，定位到HKEY_CLASSES_ROOT，然后你就会发现有大量的.NET类的ProgId和CLSID，这样我们就可以通过这些特征信息来创建并使用这些对象。
