I want to save my file in disk. I have,

public async Task SaveFileContentsAsync(string filePath, Stream stream)
{
        using (var fileStream = new FileStream(filePath, FileMode.Create))
        {
            await stream.CopyToAsync(fileStream);// await in using is required
        }
}

From my controller I am calling this as,

await _fileService.SaveFileContentsAsync(fullPath, httpPostedFileBase.InputStream)

My file is saving but with 0 KB. What is the issue here?

Your action should be Task, and you must await _fileService.SaveFileContentsAsync(fullPath, httpPostedFileBase.InputStream) – Fals Oct 13 '14 at 18:30
@Fals returning `Task` is fine; that does not appear to be the action method – Marc Gravell Oct 13 '14 at 18:34
Is the posted code correct? I don't see a return statement on public async Task SaveFileContentsAsync(string filePath, Stream stream). – Moby Disk Oct 13 '14 at 18:35
@MobyDisk there doesn't need to be; it is the `async` equivalent of a `void` method. – Marc Gravell Oct 13 '14 at 18:35
@MarcGravell, I found the answer at stream.Position = 0, http://stackoverflow.com/questions/9349571/stream-copyto-file-empty-asp-net – Imran Qadir Baksh - Baloch Oct 13 '14 at 18:37

@user960567 ah, good catch - I've linked the two questions – Marc Gravell Oct 13 '14 at 18:46
