using System.Linq;
using DocuWare.Platform.ServerClient;

namespace DocuWare.PlatformClientExamples
{
    static partial class Examples
    {
        public static FileDownloadResult DownloadSingleDocumentContent(ServiceConnection connection, int docId, string fileCabinetId)
        {
            var document = connection.GetFromDocumentForDocumentAsync(docId, fileCabinetId).Result;
            var downloadedFile = Examples.DownloadDocumentContent(document);

            Console.WriteLine("Copy document {0} with content type {2} to {1}.", 
                docId, downloadedFile.FileName, downloadedFile.ContentType);
            using (var file = System.IO.File.Create(downloadedFile.FileName))
            using (var stream = downloadedFile.Stream)
                stream.CopyTo(file);

            return downloadedFile;
        }
    }

Download a document to a file asynchronously

The header fields can be accessed straight forward in the asynchronous API.

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DocuWare.Platform.ServerClient;

namespace DocuWare.PlatformClientExamples
{
    static partial class ExamplesAsync
    {
        public static async Task<FileDownloadResult> DownloadSingleDocumentContentAsync(ServiceConnection connection, int docId, string fileCabinetId)
        {
            var document = await connection.GetFromDocumentForDocumentAsync(docId, fileCabinetId).ConfigureAwait(false);
            var downloadedFile = await DownloadDocumentContentAsync(document).ConfigureAwait(false);

            Console.WriteLine("Copy document {0} with content type {2} to {1}.", 
                docId, downloadedFile.FileName, downloadedFile.ContentType);

            using (var file = System.IO.File.Create(downloadedFile.FileName))
            using (var stream = downloadedFile.Stream)
                await stream.CopyToAsync(file).ConfigureAwait(false);

            return downloadedFile;
        }
    }
