好吧，您可能无法从那个"应用程序中获取数据，因为那个"应用程序可能不是设计成库，也不是.NET程序集.

首先，您需要将C ++应用程序转换为DLL并导出一些API.您有两种选择.

第一个选择是:仅使用原始类型创建API，然后使用P/Invoke将该API封装在.NET程序集中.参见 http://en.wikipedia.org/wiki/P/Invoke [ http://msdn.microsoft.com/en-us/library/x0w2664k. aspx [ ^ ].

其余部分取决于您要从网站获得的功能. (请在对问题的评论中看到我的问题.)

Well, you cannot probably take data from "that" application, because "that" application is probably not designed to be a library, and it is not a .NET assembly.

First, you need to transform your C++ application to a DLL and export some API. You have two options.

First option is: creating the API only using primitive types, wrapping this API in a .NET assembly using P/Invoke. See http://en.wikipedia.org/wiki/P/Invoke[^].

Second option: you can re-write your legacy C++ application into C++/CLI class library. You can 1) rewrite all the code from C++ to C++/CLI, 2) you can create a mixed mode assembly (managed+unmanaged) and add some manages code "ref" classes and/or structures to your unmanaged code. On top of this DLL, you should have managed API which you can use by your ASP.NET project. You should reference this mixed-mode or pure-managed assembly as any other .NET assembly. For more detail, see: http://msdn.microsoft.com/en-us/library/x0w2664k.aspx[^].

The rest of it depends on the functionality you want get get from your Web site. (Please see my questions in my comment to the question.)
