如何使用c#？在Dailymotion上上传视频？？有人有完整的密码吗？

我希望用c代码上传dailymotion上的视频，但dailymotion不提供用c代码上传视频的c代码

我在dailymotion文档api上搜索，发现这不是显式的curl代码：

curl -F 'access_token=...' \
     -F 'url=http://upload-02.dailymotion.com/files/5ccb48b8e8aef3fcb8959739f993e1b9.3gp' \
     https://api.dailymotion.com/me/videos

我试着转置，但不起作用：

 string contentFile = "c:\name_of_my_video_file.flv";
            byte[] byteArray = Encoding.ASCII.GetBytes(contentFile);
            MemoryStream fs = new MemoryStream(byteArray);

            // Provide the WebPermission Credintials
            // Create a request using a URL that can receive a post. 
            string uri = "https://api.dailymotion.com/me/videos";
            WebRequest request = WebRequest.Create(uri);
            // Set the Method property of the request to POST.
            request.Method = "POST";
            request.Credentials = new NetworkCredential("logindailymotion","passworddailymotion");

            // Create POST data and convert it to a byte array.
            string postData = "access_token=my_api_key&url=http://upload-02.dailymotion.com/files/name_of_my_video_file.flv";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/x-www-form-urlencoded";
            // Set the ContentLength property of the WebRequest.
            request.ContentLength = byteArray.Length;
            // Get the request stream.

            // Notify the server about the size of the uploaded file
            request.ContentLength = fs.Length;

            // The buffer size is set to 2kb
            int buffLength = 2048;
            byte[] buff = new byte[buffLength];
            int contentLen;

            // Opens a file stream (System.IO.FileStream) to read the file to be uploaded
            //FileStream fs = fileInf.OpenRead();

            try
            {
                // Stream to which the file to be upload is written
                Stream strm = request.GetRequestStream();

                // Read from the file stream 2kb at a time
                contentLen = fs.Read(buff, 0, buffLength);

                // Till Stream content ends
                while (contentLen != 0)
                {
                    // Write Content from the file stream to the FTP Upload Stream
                    strm.Write(buff, 0, contentLen);
                    contentLen = fs.Read(buff, 0, buffLength);
                }

                // Close the file stream and the Request Stream
                strm.Close();
                fs.Close();
            }
            catch (Exception ex)
            {
                throw ex;
            }

        }

有更好的c代码文档吗

有人的代码正确吗？

我创建了一个完整的示例来回答您的问题并上传视频。现在可以使用了

同样，.

我不知道上传部分，但您是否使用ASCII作为视频文件？？-使用File.ReadAllBytes（）不是更好吗？我编译并执行了您的代码，程序处理得很好，没有错误（请参阅：）上的控制台结果。但没有发生任何事情：没有上传视频。@user101869
