1HttpApplication app = sender as HttpApplication;
2            HttpWorkerRequest request = GetWorkerRequest(app.Context);
3

5           
6            string sContentType = app.Request.ContentType.ToLower();
7            byte[] arrBoundary = GetMultipartBoundary(sContentType);
8            int ContentLength = app.Request.ContentLength; //信息体的总长度

10            DataReader dataReader = new DataReader(app.Context.Request.ContentEncoding,

arrBoundary);
11            DateTime startDate = DateTime.Now;
12            byte[] arrBuffer = request.GetPreloadedEntityBody();
13            if (arrBuffer == null)
14            {
15                arrBuffer = new Byte[0];
16                tempFile.Close();
