 ## Examples  
  The following example is a command-line utility that calculates the number of bytes in the files in each directory whose name is passed as a command-line argument. Rather than executing a longer code path that instantiates a <xref:System.IO.FileStream> object and retrieves the value of its <xref:System.IO.FileStream.Length%2A?displayProperty=nameWithType> property for each file in the directory, the example simply calls the <xref:System.Threading.Tasks.Task.FromResult%2A> method to create a task whose <xref:System.Threading.Tasks.Task%601.Result%2A?displayProperty=nameWithType> property is zero (0) if a directory has no files.
