Answer 1

You can do it this way:

DataLakeDirectoryClient directoryClient =
    fileSystemClient.GetDirectoryClient("my-directory/my-subdirectory");
DataLakeFileClient fileClient = await directoryClient.CreateFileAsync("uploaded-file.txt");

FileStream fileStream =
    File.OpenRead("C:\\Users\\contoso\\Temp\\file-to-upload.txt");

long fileSize = fileStream.Length;

await fileClient.AppendAsync(fileStream, offset: 0);

await fileClient.FlushAsync(position: fileSize);
