C# 在C中发出CURL请求#

我想使用c#调用一些Curl请求。我搜索并看到了一些例子，但它们对我不起作用。我的命令如下：

登录示例：

curl -X GET \
--digest -u "<username>:<password>" http://<IP>/api/auth/login \
--cookie-jar <cookieFile>

---

“GetRequestStream”函数出现运行时错误：“无法发送具有此谓词类型的内容正文。”

我认为问题在于内容类型

 request.ContentType = "application/json";

---

请参阅HttpClient、WebClient或HttpWebRequest类……这到底为什么标记为PHP？

curl -X POST \
--data "{\"filter\" : [ { \"Name\" : \"ID\", \"Op\" : \"=\", \"Value\" : \"1\" } ], \
\"count\" : 1, \"offset\" : 0, \"brief\" : true, \"includeResultsetSize\" : false }" \
http://<IP>/api/$/database/getCrossings --cookie <cookieFile>

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://192.168.5.204/api/auth/login");
    request.Method = "GET";
    request.Accept = "application/json";
    request.Credentials = new NetworkCredential("user", "pass");
    request.UserAgent = "curl/7.37.0";
    request.ContentType = "api/auth/login";

    using (var streamWriter = new StreamWriter(request.GetRequestStream()))
    {}

 request.ContentType = "application/json";
