我正在开发一个 android 应用程序，我可以将视频、音频和图像从 android 设备上传到 WCF REST 服务。它正在完美地上传 10MB 大小的视频文件，但是当我尝试上传1GB的视频文件时，它没有上传到服务器。我想制作一个应用程序，我可以将文件大小上传到3gb 到 4gb。我怎样才能实现这一点，任何人都可以指导我实现这种情况。

wcf 服务代码： 

public string PostImage(Stream stream)
        {
MultipartParser parser = new MultipartParser(stream);

            if (parser.Success)
            {
                string fileName = parser.Filename;
                string contentType = parser.ContentType;
                byte[] fileContent = parser.FileContents;
                FileStream fileToupload = new FileStream("D:\\FileUpload\\" + fileName, FileMode.Create);
                fileToupload.Write(fileContent, 0, fileContent.Length);
                fileToupload.Close();
                fileToupload.Dispose();
                stream.Close();
                return "Success !!!";
            }
            else
            {
                return "Exception!!!";
            }
        }

web.config 文件：

<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>

    <compilation debug="true" targetFramework="4.5" />

      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>

</configuration>

我的安卓代码：

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httpost = new HttpPost("http://192.169.3.34/Service1.svc/upload");
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
        entity.addPart("fileContents", new FileBody(new File("/mnt/sdcard/hi.mp4")));
        httpost.setEntity(entity);
        HttpResponse response;
        response = httpclient.execute(httpost);

当我尝试上传 1GB 的文件时，我得到的状态码为 404。

我需要在哪里进行更改以使我的代码将 2gb 到 5gb 的文件大小上传。谁能帮我解决这个问题。
