我有以下代码来使用Simple.oData.Client获取oData。它有效。当我通过手机上网时;但是，当我通过代理保护的公司以太网连接时，它给我以下错误。我怎么能处理它？</ p>

async partial  void Click_TouchUpInside (UIButton sender)
        {
            var client= new ODataClient("http://services.odata.org/Northwind/Northwind.svc/");

            Console.WriteLine("before await");

            try {
            var packages = await client
                .For("Customers").
                FindEntriesAsync();
                foreach (var package in packages)
                 {
                  //Console.WriteLine(package["CompanyName"]);
                  Console.WriteLine(package);
                 }
                }
                catch(AggregateException e) {
                   Console.WriteLine(e);
                   Console.WriteLine(e.InnerException);
                }
                Console.WriteLine("after await");
       }

以下是解决方案：

async partial  void Click_TouchUpInside (UIButton sender)
        {

            ODataClientSettings settings = new ODataClientSettings();

            NetworkCredential proxyNC = new NetworkCredential("Username", "password");

            settings.OnApplyClientHandler= (System.Net.Http.HttpClientHandler clientHandler) => {

                clientHandler.Proxy = new WebProxy("yourproxy.com",false,null, proxyNC);
                clientHandler.UseProxy = true;
            };
            settings.UrlBase = "http://services.odata.org/Northwind/Northwind.svc/";
            var client= new ODataClient(settings);

            Console.WriteLine("before await");

            try {
            var packages = await client
                .For("Customers").
                FindEntriesAsync();
                foreach (var package in packages)
                 {
                  //Console.WriteLine(package["CompanyName"]);
                  Console.WriteLine(package["CompanyName"]);
                 }
                }
                catch(AggregateException e) {
                   Console.WriteLine(e);
                   Console.WriteLine(e.InnerException);
                }
                Console.WriteLine("after await");
       }

这意味着您尝试连接的端点未侦听连接。

Simple.oData.Client中的System.Net.Sockets.SocketException
