本文详细阐述了如何使用公共字符串方法实现文件上传，并通过异步任务处理上传过程中的复杂情况。

public string UploadFile()
        {
            if (Request.Content.IsMimeMultipartContent())
            {
                //Save file
                MultipartFormDataStreamProvider provider = new MultipartFormDataStreamProvider(HttpContext.Current.Server.MapPath("/UploadUser/"));

                string filename = "Not set";

                IEnumerable<HttpContent> parts = null;
                Task.Factory
                    .StartNew(() =>
                    {
                        parts = Request.Content.ReadAsMultipartAsync(provider).Result.Contents;
                        filename = "Set Success";
                    },
                    CancellationToken.None,
                    TaskCreationOptions.LongRunning, // guarantees separate thread
                    TaskScheduler.Default)
                    .Wait();

                return filename;
            }
            else
            {
                return "Invalid.";
            }
        }
