I need to save some data to two files in D365FO, I have made this code to show the problem.

public static void main(Args _args)
    { 
        str filePath,
         filePathAndName,
         fileContent = "01234567890123456789";
        ;
        // prepare file name
        filePath = System.IO.Path::GetTempPath();
        filePathAndName = filePath   'f'   guid2str(newGuid())   '.txt';
        // Save file
        File::SendStringAsFileToUser(fileContent, filePathAndName);

        fileContent = "MY New Content";
        File::SendStringAsFileToUser(fileContent, filePathAndName);

        info(filePath);
        info(filePathAndName);
        info("done");
    }

In this case only the last file is saved.

Any tips to how I can save data to two different files in D365FO?

A solution may be opening the files in new tabs. Here is a quick & dirty implementation:

// Creating files File::SendStringAsFileToUserNewTab("01234567890123456789", 'file1.txt'); File::SendStringAsFileToUserNewTab("MY New Content", 'file2.txt'); info("done"); // New methods of File class [ExtensionOf(classStr(File))] final class My_File_Extension { public static void SendStringAsFileToUserNewTab(str content, str fileName, System.Text.Encoding encoding = System.Text.Encoding::get_UTF8(), ClassName fileUploadStrategyClassName = classstr(FileUploadTemporaryStorageStrategy)) { System.Byte[] byteArray = encoding.GetBytes(content); System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray); File::SendFileToUserNewTab(stream, fileName, fileUploadStrategyClassName); } public static void SendFileToUserNewTab(System.IO.Stream stream, str fileName, ClassName fileUploadStrategyClassName = classstr(FileUploadTemporaryStorageStrategy)) { Browser br = new Browser(); str downloadUrl; downloadUrl = File::SendFileToTempStore(stream, fileName, fileUploadStrategyClassName, true); if (downloadUrl != "") { br.navigate(downloadUrl, true, false); } else { warning("@ApplicationPlatform:DownloadFailed"); } } }

Hi Martin.

That does solve the problem.

But it also leaves me with another question, should I even use the SendStringAsFileToUser function to start with, or is there some other way to get files to a user in D365FO? (Like send the files to ftp or email)

The system can't see the users's workstation, and doesn't have access to it. So the only way to provide them directly to the user is to offer the files via the browser and let the user download them.

But of course you can also use FTP or email.

Regarding email, you can use SysMailerMessageBuilder class to create an email message (addAttachment() is used for attachments) and send it with SysMailerFactory::sendInteractive() or SysMailerFactory::sendNonInteractive().
