Question

情景：
首先，请考虑我使用HttpClient课程，而不是WebRequest，我知道这里有很多相关问题，但所有答案都是针对WebRequest的。

我制作了一个Web Api应用程序，以这种方式设置以下标题以便下载.txt文件：

resp.Content = new StringContent(result, System.Text.Encoding.UTF8, "text/plain");
resp.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
{
    FileName = _datacontext.GetAppConfig("814FileNameHeader") + DateTime.Now.ToString("yyyyMMdd") + ".txt"
};
resp.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

从其他应用程序创建HttpClient后连接到此方法一切正常，检索200和文件的内容。但我无法获取标题以便读取文件名。

TRIES MADE：

使用REST客户端我可以阅读以下标题属性：

内容 - 处置：附件;文件名= 814Entes_PG_20160114.txt

从代码我可以调试它，我发现标题在＆＃34; invalidHeaders＆＃34;但我无法达到这个价值：

问题：

如何设置此设置并毫无疑问地从客户端获取？

更新：

这些是我尝试获取标题：原文：

                using (var httpClient = new HttpClient())
            {
                httpClient.BaseAddress = new Uri(uri);
                string authentication = string.Concat(authenticationArgs[0], ":", authenticationArgs[1]);
                httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Basic " + Base64Encode(authentication));
                httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                HttpRequestMessage req = new HttpRequestMessage(HttpMethod.Post, "Report/" + type);
                req.Content = new StringContent("");
                HttpResponseMessage response = await httpClient.SendAsync(req);
                Console.WriteLine(response.StatusCode);
                if (response.IsSuccessStatusCode)
                {
                    string stream = response.Content.ReadAsStringAsync().Result;
                    Console.Write("Respuesta servicio: " + stream);
                    Console.WriteLine(stream);

                  string cp =  response.Headers.GetValues("Content-Disposition").ToString();
                }

第二个我尝试了一些SO调查：

        using (var httpClient = new HttpClient())
        {
            httpClient.BaseAddress = new Uri(uri);
            string authentication = string.Concat(authenticationArgs[0], ":", authenticationArgs[1]);
            httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "Basic " + Base64Encode(authentication));
            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            HttpRequestMessage req = new HttpRequestMessage(HttpMethod.Post, "Report/" + type);
            req.Content = new StringContent("");
            HttpResponseMessage response = await httpClient.SendAsync(req);
            Console.WriteLine(response.StatusCode);
            if (response.IsSuccessStatusCode)
            {
                string stream = response.Content.ReadAsStringAsync().Result;
                Console.Write("Respuesta servicio: " + stream);
                Console.WriteLine(stream);
                string cp = "";
                HttpHeaders headers = response.Headers;
                IEnumerable<string> values;
                if (headers.TryGetValues("Content-Disposition", out values))
                {
                    cp = values.ToString();
                }

            }

Answer 1

如果您尝试获取内容的标题，则应该来自response.Content.Headers

无法获得标题＆＃34; Content-Disposition＆＃34;使用C＃中的httpclient
