我想做一个上传控件的进度条，用AJAX每1毫秒刷新一次，所以需要FileUpload每1毫秒返回当前上传文件的字节数，请问怎样获取？？？

string filePath = Server.MapPath("~/Upload");
string fileName=FileUpload1.PostedFile.FileName;
int fileLength = FileUpload1.PostedFile.ContentLength;
int upLoadedLength = 0;

//缓存
int bufferSize = 1;
byte[] buffer = new byte[bufferSize];

//保存字节
using (FileStream fs = new FileStream(Path.Combine(filePath, fileName),FileMode.Create))
{
int i=0;
while (upLoadedLength < fileLength)
{
//从输入流放进缓冲区
int uploadingLength = FileUpload1.PostedFile.InputStream.Read(buffer, 0, bufferSize);
fs.Write(buffer, 0, uploadingLength);
upLoadedLength += uploadingLength;
float precent = upLoadedLength / fileLength;
this.progressContent.Style["width"] = (precent * 400).ToString() + "px";
this.progressContent.InnerHtml = (precent*100).ToString()+"%";
//线程睡眠上传就更慢这样就可以看到进度条了
//System.Threading.Thread.Sleep(100);
}

}

HttpPostedFile hpf = this.FileUpload1.PostedFile;
string FileSize = Convert.ToString(Convert.ToInt32(hpf.ContentLength.ToString()) / 1024);// +"KB";获得上传文件的大小

        int fileLength = FileUpload1.PostedFile.ContentLength;

        int upLoadedLength = 0;



        //缓存

        int bufferSize = 1;

        byte[] buffer = new byte[bufferSize];



        //保存字节

        using (FileStream fs = new FileStream(Path.Combine(filePath, fileName),FileMode.Create))

        {

            int i=0;

            while (upLoadedLength < fileLength)

            {

                int uploadingLength = FileUpload1.PostedFile.InputStream.Read(buffer, 0, bufferSize);

                fs.Write(buffer, 0, uploadingLength);

                upLoadedLength += uploadingLength;

                this.progressContent.InnerHtml = (precent*100).ToString()+"%";

                //线程睡眠 上传就更慢 这样就可以看到进度条了
