p/Invoke可以使用工具辅助自动生成，以减少混淆
1、官方的支持

微软的官方扩展上也有很多
开源的工具

看起来微软自己也是深受.NET蹩脚的P/Invoke支持的毒害，因此无奈之余发布了P/Invoke Interop Assistant工具，你可以去下面这个链接来下载这个工具：

实际上这个工具已经开源了，你可以从这里http://www.codeplex.com/clrinterop/下载到它的源代码

The first tool is the PInvoke Visual Studio Add-in from Red Gate Software (the UK-based provider of various development tools, including Reflector Pro). It appears to be a Visual Studio Add-in for VS2003 and 2005 (I can’t see an update for VS2008 or 2010, which also means I can’t try it). The tool provides simplified access to the excellent PInvoke.net website, to which I often refer when developing .NET apps. I don’t actually use that many P/Invoke statements that I feel I need an Add-In, though – which is perhaps why the add-in doesn’t appear to have been updated for more recent Visual Studio versions – but it seemed worth mentioning.
The second – in my opinion more interesting – tool is the P/Invoke Interop Assistant(here’s a more in-depth article, the CodePlex hosting site and a Channel 9 interview with one of the authors). This tool generates P/Invoke signatures for use from C# and VB.NET, as well as the ability to determine the P/Invoke signatures used in compiled binaries:
- Generating P/Invoke declarations while searching for commonly-used (presumably Win32) functions, structures, messages, etc.
