如果获取上传文件的进度？



try

            {

                FileInfo file = new FileInfo(fileNamePath);

                

                string fileNameExt = file.Extension;





                if (CheckVideoFileType(fileNameExt))

                {

                    string fileName = GetNewFileName() + fileNameExt;

                    if (toFilePath.EndsWith("/") == false) toFilePath = toFilePath + "/";

                    

                    string serverFileName = toFilePath + fileName;

                                        

                    string toFileFullPath = HttpContext.Current.Server.MapPath(toFilePath);



                    

                    if (!Directory.Exists(toFileFullPath))

                    {

                        Directory.CreateDirectory(toFileFullPath);

                    }



                                    

                    string toFile = toFileFullPath + fileName;



                          

                    WebClient myWebClient = new WebClient();

                    

                    myWebClient.Credentials = CredentialCache.DefaultCredentials;

                    



                          

                    FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.Read);

                          

                    BinaryReader r = new BinaryReader(fs);

     

                    byte[] postArray = r.ReadBytes((int)fs.Length);

                    Stream postStream = myWebClient.OpenWrite(toFile, "PUT");

if (postStream.CanWrite)

                    {。。。。。。}
