如何通过 C# WebClient 发送 HTTP DELETE 请求？

Question

登录后，我可以从远程系统获得令牌。例如 authentication_token 是 8JySqFVx_pKx_3nx67AJ 我可以通过这个命令从终端注销

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X DELETE https://sample.com\?authentication_token\=8JySqFVx_pKx_3nx67AJ

我需要从 C# 中做到这一点。我可以像这样发送 POST 请求：

        WebClient wc = new WebClient();
        string baseSiteString = wc.DownloadString("https://sample.com");
        string csrfToken = Regex.Match(baseSiteString, "<meta name=\"csrf-token\" content=\"(.*?)\" />").Groups[1].Value;
        string cookie = wc.ResponseHeaders[HttpResponseHeader.SetCookie];

        wc.Headers.Add(HttpRequestHeader.Cookie, cookie);
        wc.Headers.Add(HttpRequestHeader.ContentType, "application/json; charset=utf-8");
        wc.Headers.Add(HttpRequestHeader.Accept, "application/json, text/javascript, */*; q=0.01");
        wc.Headers.Add("X-CSRF-Token", csrfToken);
        wc.Headers.Add("X-Requested-With", "XMLHttpRequest");


        string dataString  =  @"{""user"":{""email"":""sample@sample.com"",""password"":""sample_password""}}";
        byte[] dataBytes = Encoding.UTF8.GetBytes(dataString);
        byte[] responseBytes = wc.UploadData(new Uri("https://sample.com/auth.json"), "POST", dataBytes);
        string responseString = Encoding.UTF8.GetString(responseBytes);

如何从 C# 发送 DELETE 请求，其中 authentication_token 将是一个参数？

解决了，我使用了WebClient。

        var wc2 = new WebClient();
        string baseSiteString2 = wc2.DownloadString("https://sample.com");
        string csrfToken2 = Regex.Match(baseSiteString2, "<meta name=\"csrf-token\" content=\"(.*?)\" />").Groups[1].Value;
        string cookie2 = wc2.ResponseHeaders[HttpResponseHeader.SetCookie];

        wc2.Headers.Add(HttpRequestHeader.Cookie, cookie2);
        wc2.Headers.Add(HttpRequestHeader.ContentType, "application/json; charset=utf-8");
        wc2.Headers.Add(HttpRequestHeader.Accept, "application/json, text/javascript, */*; q=0.01");
        wc2.Headers.Add("X-CSRF-Token", csrfToken2);
        wc2.Headers.Add("X-Requested-With", "XMLHttpRequest");


        string dataString2 = "";// @"{""name"":""Megan"",""regi_number"":4444}";
        byte[] dataBytes2 = Encoding.UTF8.GetBytes(dataString2);
        string finalUrl = "https://sample.com?authentication_token=" + authentication_token;
        byte[] responseBytes2 = wc2.UploadData(new Uri(finalUrl), "DELETE", dataBytes2);
        string responseString2 = Encoding.UTF8.GetString(responseBytes2);
        authentication_token = "";
