问题描述

大家帮帮忙！我这个上传文件的方法为什么会限制文件的大小啊?文件超过一定的大小，上传就失败了！

    private void PostFile(string filename)    {        FileStream stream = new FileInfo(filename).OpenRead();        var shortfilename = Path.GetFileName(filename);        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(""http://120.24.97.123/APPService.svc/UploadFile/"" + OperationOrderID + ""/"" + shortfilename);        request.Method = ""POST"";        //request.ContentType = ""application/json;charset=UTF-8"";        //request.ContentType = ""application/x-www-form-urlencoded"";        request.ContentLength = stream.Length;        Stream requestStram = request.GetRequestStream();        int bytesread = 0;        //从流中读取字节块并将该数据写入给定缓冲区buffer中        Byte[] buffer = new Byte[4096];        bytesread = stream.Read(buffer 0 4096);        long UploadByte = bytesread;        while (bytesread != 0)        {            if (bytesread == 4096)            {                requestStram.Write(buffer 0 4096);            }            else            {                requestStram.Write(buffer 0 bytesread);            }            SetText(shortfilename + "" 文件正在上传中("" + FormatFileSize(UploadByte) + ""/"" + FormatFileSize(stream.Length) + "")"");            bytesread = stream.Read(buffer 0 4096);            UploadByte = UploadByte + bytesread;        }        stream.Close();        stream.Dispose();        requestStram.Close();        requestStram.Dispose();        SetText(shortfilename + "" 文件上传成功..."");        Stream getStream = request.GetResponse().GetResponseStream();        //StreamReader smd = new StreamReader(getStream);        //SetText(smd.ReadToEnd());        //byte[] resultByte = new byte[200];        request.Abort();        //getStream.Read(resultByte 0 resultByte.Length);        //Console.WriteLine(Encoding.UTF8.GetString(resultByte));        //GetFiles();    }

解决方案

60m

解决方案二：
60m

解决方案三：
是不是request.contentlength和4096冲突，不匹配造成的？
