我有关于上传文件到Youtube的问题
在对网页进行调查之后，我找到了链接https://developers.google.com/youtube/2.0/developers_guide_protocol_direct_uploading#Sending_a_Direct_Upload_API_Request并且有一些实现上传的发现 . 但现在我遇到了问题清单如下：
httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + access_token);
httpClient.DefaultRequestHeaders.Add("GData-Version", "2.0");
httpClient.DefaultRequestHeaders.Add("X-GData-Key", "key=" + clientID);
httpClient.DefaultRequestHeaders.Add("Slug", "video.wav");
//httpClient.DefaultRequestHeaders.Add("Content-Type", "multipart/related; boundary=\"f93dcbA3\"");
httpClient.DefaultRequestHeaders.Add("Content-Length", "4141440");
httpClient.DefaultRequestHeaders.Add("Connection", "close");
它将发生异常，其原因是
Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.
所以我改变了方式
var requset = new HttpRequestMessage( new HttpMethod("post"), "https://gdata.youtube.com//feeds/api/users/default/subscriptions");
requset.Headers.Add("Host", "gdata.youtube.com");
requset.Headers.Add("Authorization", "Bearer " + access_token);
requset.Headers.Add("GData-Version", "2.0");
requset.Headers.Add("X-GData-Key", "key=" + simpleKey);
string str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><entry xmlns=\"http://www.w3.org/2005/Atom\" xmlns:yt=\"http://gdata.youtube.com/schemas/2007\"> <category scheme=\"http://gdata.youtube.com/schemas/2007/subscriptiontypes.cat\" term=\"channel\"/> <yt:username>GoogleDevelopers</yt:username></entry>";
StringContent cnt = new StringContent(str);
cnt.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/atom+xml");
cnt.Headers.ContentLength = 270;
但仍然没有任何影响，有人能给我一些提示吗？
非常感谢
