如何使用WPF单击一次应用程序部署非托管DLL？

我有一个使用非托管dll的WPF单击一次应用程序。

I have a WPF click-once application that makes use of an unmanaged dll.

在本地调试时，我只是将dll复制到了debug / bin文件夹中。

When debugging locally I have just copied the dll into the debug/bin folder.

如何将dll包含在项目（VS2010）中，以便它可以部署并可供应用程序访问？

How can I include the dll in the project (VS2010) so it is deployed and accessible to the application?

我尝试将其添加为资源并设置内容和始终复制，该文件似乎确实存在于设置/部署文件中，但是应用程序看不到它。

I have tried adding it as a Resource and setting "Content" and "Copy Always", and the file does seem to be present in the setup/deployment files, however the application is not able to see it.

如果有帮助，这是我用来访问非托管DLL中的方法的代码示例。

If it helps, this is an example of the code I use to access the methods in the unmanaged DLL.

 [DllImport("ODBC_VER_DETECT.dll")]
 extern private static long GetCompanyFileVersion([MarshalAs(UnmanagedType.LPStr)] String sDataBase,
                                                 [MarshalAs(UnmanagedType.LPStr)] StringBuilder sVersion);
