UploadFileControl.SaveAs（fileName）的替代方案

Question

我可以使用另一种方法，在上传文件时获取“写入的字节数”或类似内容吗？我想要一个进步，这是所写数据的实际进展，或者使用这个类和方法是不可能的？如果没有，请研究什么途径？

感谢。

基本示例：

if(FileUpload1.HasFile)
{
  savePath += FileUplaod1.FileName;
  FileUpload1.SaveAs(savePath); ///  Here is where I want to do a stream or some way to grab
   //bytes written so I can do an async on it and show the progress, not wait until it is copleted, and then show a label status of "completed". Doing this for a form that has to be non-html5 compatibale. That is why I am not using a different method.  

}

Answer 1

HttpPostedFile file = context.Request.Files [“userfile”];             file.ContentLength;

Answer 2

我明白了。昨晚这么晚，完全忽略了这个。

bytes[] filebytes = UplaodFile1.FileBytes ;
//Now I can send to stream.....
