代码部分

string fileTime = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();//以时间为图片命名 string fileExtName = UploadFileName.Substring(UploadFileName.LastIndexOf("."));

string filename = UploadFileName.Substring(UploadFileName.LastIndexOf("\\") + 1);

UploadFileDestination = HttpContext.Current.Request.PhysicalApplicationPath;

UploadFileDestination +=“\\UploadFiles\\”;     //文件路径

bmp.Save(UploadFileDestination + fileTime + fileExtName);

     lblchan.Text = fileTime + fileExtName;     

图片可以保存。但是给 lblchan.Text 赋值这一步，没有赋值成功。怎么才可以给lblchan.Text获取到值。
