.NET P/Invoke Revisited

摘要

In the July 2003 installment of the .NET column I covered the basics of Win32~(~R) interoperation with the Microsoft" .NET Framework (P/Invoke). Based on reader feedback, this topic is worthy of further coverage, so I have decided to revisit P/Invoke in this column. It will build upon the information in the July 2003 issue, so if you are not familiar with basic .NET interop, I suggest reviewing that column (see http://msdn.microsoft.com/msdnmag/issues/ 03/07/NET) before digging into this one. This month I am going to delve into the interop details of marshaling data structures to native functions. In a future piece, I hope to address calls into native code that calls back into your managed code, and I'll work through an interop case study using Windows" Forms. So let's get started on marshaling structures.
