如何使用.pem文件或（.crt和.key文件）进行RestSharp接听电话？

Question

我有一个.crt文件和一个.key文件，必须使用C＃在我的rest调用中发送该文件。我到处都找到了将这些文件转换为单个.pfx文件的建议，但问题是服务器不接受pfx。它接受.pem或同时需要.crt和.key文件。我真的可以使用RestSharp发送一个.pem文件和一个get调用吗？我尝试使用以下代码，但响应始终显示“ ACL拒绝连接”。预先感谢您的任何帮助。

var client = new RestClient(@"https://midway-itg-stage.glb1.hpe.com/files/storeeasy/");

            //ServicePointManager.Expect100Continue = true;
            ServicePointManager.DefaultConnectionLimit = 9999;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

            string certFile = @"C:\test_openssl.pem";
            X509Certificate2 certificate = new X509Certificate2(certFile,"file");
            client.ClientCertificates = new X509CertificateCollection() { certificate };
            //client.Proxy = new WebProxy();
            var restrequest = new RestRequest(Method.GET);
            //restrequest.AddHeader("Cache-Control", "no-cache");
            restrequest.AddHeader("Accept", "application/json");
            restrequest.AddHeader("Content-Type", "application/json");
            IRestResponse response = client.Execute(restrequest);
            Console.WriteLine(JsonConvert.SerializeObject(response));
            Console.WriteLine();
            Console.WriteLine();
            return response.Content;`
