哪位高人帮忙看一下呀，怎么始终传不上去文件呀

以下是WP8 C#实现源码

void pct_Completed(object sender, PhotoResult e)
{
    if (e.Error != null)
    {
        MessageBox.Show(e.Error.Message);
    }
    else if (e.TaskResult.Equals(TaskResult.OK))
    {
        UploadStateObject uso = new UploadStateObject();
        uso.Stream = e.ChosenPhoto;
        uso.Boundary = "----WebKitFormBoundary3jJRGWjdL0V3CTvW";
        uso.OriginalFileName = e.OriginalFileName;

        HttpWebRequest request = HttpWebRequest.CreateHttp(new Uri(String.Format(liveUpload, id), UriKind.Absolute));
        request.Method = "POST";
        request.CookieContainer = cc;
        request.ContentType = "multipart/form-data; boundary=" + uso.Boundary;
        request.AllowAutoRedirect = true;

        uso.Request = request;

        request.BeginGetRequestStream(GetRequestStream, uso);
        pi.IsVisible = true;
    }
}

private void GetRequestStream(IAsyncResult ar)
{
    UploadStateObject uso = ar.AsyncState as UploadStateObject;

    Stream bw = uso.Request.EndGetRequestStream(ar);

    String[] fileName = uso.OriginalFileName.Split(new char[] { '\\' });

    Byte[] boundary = Encoding.UTF8.GetBytes(uso.Boundary + "\r\n");
    Byte[] disposition = Encoding.UTF8.GetBytes("Content-Disposition: form-data; name=\"file\"; filename=\"wp.jpg\"\r\n");
    Byte[] contentType = Encoding.UTF8.GetBytes("Content-Type: image/jpeg\r\n\r\n");
    Byte[] endBoundary = Encoding.UTF8.GetBytes("\r\n" + uso.Boundary + "--");




    Byte[] ff = Encoding.UTF8.GetBytes("Content-Disposition: form-data; name=\"localUrl\"");
    Byte[] va = Encoding.UTF8.GetBytes("\r\n\r\nwp.jpg\r\n");
    bw.Write(boundary, 0, boundary.Length);
    bw.Write(ff, 0, ff.Length);
    bw.Write(va, 0, va.Length);


    bw.Write(boundary, 0, boundary.Length);
    bw.Write(disposition, 0, disposition.Length);
    bw.Write(contentType, 0, contentType.Length);

    Byte[] buffer = new Byte[2048];
    Int32 len = 0;
    while ((len = uso.Stream.Read(buffer, 0, buffer.Length)) != 0)
    {
        bw.Write(buffer, 0, len);
    }
    bw.Write(endBoundary, 0, endBoundary.Length);

    bw.Close();
    uso.Stream.Close();

    this.Dispatcher.BeginInvoke(() =>
    {
        MessageBox.Show("发送完成");
    });

    uso.Request.BeginGetResponse(GetResponse, uso);
}

private void GetResponse(IAsyncResult ar)
{
    UploadStateObject uso = ar.AsyncState as UploadStateObject;
    HttpWebResponse response = (HttpWebResponse)uso.Request.EndGetResponse(ar);
}

class UploadStateObject
{
    public HttpWebRequest Request { get; set; }
    public Stream Stream { get; set; }
    public String Boundary { get; set; }
    public String OriginalFileName { get; set; }
}

Fiddler2监视的结果
请求Header

请求正文

服务器返回结果

服务器端是PHP开发的， 三个array分别是print_r($_REQUEST); print_r($_POST); print_r($_FILES);
C#端没有报错，而且Cookies也没有传上去，不知道是不是哪儿写错了，请高手看看。

搞了半天是Byte[] boundary = Encoding.UTF8.GetBytes(uso.Boundary + "\r\n");少加了两个-
