通过WebRequest发送文件

Question

我需要使用C＃向application / octet流的内容类型发送文件。

我可以像下面这样创建一个HttpWebRequest：

            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://test.com");
            request.Headers.Add("content-type", "application/octet-stream");
            //Add file here?

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            if (response.StatusCode == HttpStatusCode.Created)
            {
                Console.WriteLine("YAYA");
            }
            else
            {
                Console.WriteLine("OH NO MR BILL!!!!");
            }

如何在文件流中添加文件？

Answer 1

只需获取请求流，然后从源流中复制。

using (var requestStream = request.GetRequestStream())
{
    fileStream.CopyTo(requestStream);
}
