C# 在Facebook上上传照片

我想使用HttpWebRequest将照片上传到Facebook页面

我不想使用Facebook Graph API

通过live http标头，我可以获得需要发布的url和数据

user=XXXXXXXXXXXX&_a=1&_dyn=XXXXXXXXXXXXX&_req=s&fb_dtsg=AQAszPoc&ttstamp=2658165115122801199&_rev=1141676“>https://upload.facebook.com/ajax/composerx/attachment/media/saveunpublished?target_id=XXXXXXXXXXXXXX1&_user=XXXXXXXXXXXXX&_a=1&_dyn=XXXXXXXXXXXX&_req=s&fb_dtsg=AQAszPoc&ttstamp=26581651151228011199&__rev=1141676

将使用url发送的数据

我不知道如何得到这个值 内容处置：表单数据；name=“qn”

有人能帮我吗 每次我尝试上传时都会出错

我不想使用FaceBook Graph API的原因是，每当我们发布/上传它时，都会显示消息“33分钟前，通过Graph API Explore”

请帮帮我

谢谢
