| + | |||
| + | ==== [[resource]] Embedding WinSCP Executable as Resource ==== | ||
| + | |||
| + | If you want to avoid having the ''winscp.exe'' as a separate file (e.g. when whole your project is a single ''.exe'' file and you do not want to have any dependency), you can embed the ''winscp.exe'' as a resource to your own executable. | ||
| + | |||
| + | Add the ''winscp.exe'' to your Visual Studio project. Change file property //Build Action// to the //Embedded Resource//.((You cannot use [[#nuget|NuGet package]] in this case, as it does not add ''winscp.exe'' visibly to the project, so you cannot change its properties.)) | ||
| + | |||
| + | Now, before you open a session, extract the ''winscp.exe'' from resources to a temporary file using a code like: | ||
| + | |||
| + | <code csharp> | ||
| + | // Generate random, yet meaningful name of the temporary file | ||
| + | string tempName = Path.GetTempFileName(); | ||
| + | string executableName = "WinSCP." + Path.ChangeExtension(Path.GetFileName(tempName), "exe"); | ||
| + | string executablePath = Path.Combine(Path.GetDirectoryName(tempName), executableName); | ||
| + | File.Delete(tempName); | ||
| + | |||
| + | // Extract the resource to the temporary file | ||
| + | Assembly executingAssembly = Assembly.GetExecutingAssembly(); | ||
| + | string resName = executingAssembly.GetName().Name + "." + "WinSCP.exe"; | ||
| + | |||
| + | using (Stream resource = Assembly.GetExecutingAssembly().GetManifestResourceStream(resName)) | ||
| + | using (Stream file = File.Create(executablePath)) | ||
| + | { | ||
| + | resource.CopyTo(file); | ||
| + | } | ||
| + | |||
| + | try | ||
| + | { | ||
| + | using (Session session = new Session()) | ||
| + | { | ||
| + | // Use the temporarily extracted executable | ||
| + | session.ExecutablePath = executablePath; | ||
| + | |||
| + | // Connect | ||
| + | session.Open(sessionOptions); | ||
| + | |||
| + | // Your code | ||
| + | } | ||
| + | } | ||
| + | finally | ||
| + | { | ||
| + | // Clean up | ||
| + | File.Delete(executablePath); | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | ==== [[merge]] Embedding/Merging Assembly ==== | ||
| + | |||
| + | If you are using a tool like [[https://github.com/Fody/Costura|Costura.Fody]] to embed ''WinSCPnet.dll'' into your executable, you will need to set [[library_session#disableversioncheck|''Session.DisableVersionCheck'']]. The WinSCP .NET library code will be merged into the executable assembly and would compare the executable version instead its (lost) version against WinSCP executable version. | ||
