将WSDL添加到Project后，底层连接意外关闭

Question

我收到了一个WSDL文件，我想向我的应用程序添加一项服务，该服务通过该服务发送数据。

我通过以下方式添加了WSDL文件：

1. 右键单击项目 - ＆gt;添加服务参考
2. 点击高级 - ＆gt;添加Web引用
3. 将WSDL文件URL添加到URL文本框
4. 添加参考

参考出现在Web Reference文件夹下。

我添加了这段代码：

        using (var client = new getSubmitClaimWSD())
        {
            SubmitClaimRequest request = new SubmitClaimRequest()
            {
                buName = "Thermo King TSA",
                dealerNumber = "PHSDF",
                userName = "Roger",
                password = "1234",
                transactionType = "WARRANTY",
                claimLanguage = "ENG",
                serviceVersion = "1.0",
                claimType = "PARTS",
                failureDate = new DateTime(2014, 11, 26),
                faultFound = "PERFORM A FREE INSPECTION",
                inventorySerialNumber = "12352341",
                repairDate = new DateTime(2014, 11, 26),
                workOrderNumber = "testProcede1",
                conditionsFound = "test",
                workPerformed = "test",
                claimNotes = "test claim notes",
                faultLocation = "FF",
                failureDetail = "test",
                smrClaim = "N",
                forceToDraft = "Y",
                validateOnly = "N",
                commercialPolicy = "N",
                fuelSurcharge = 0,
                shopSupplies = 0,
                claimCurrency = "USD",
                workOrderSegment = "1",
                partsType = new[]
                {
                    new eachPart() {partNumber = "1234", partPrice = 100.78, partQuantity = 17, partType = "NONIR", partDescription = "test part desc"},
                    new eachPart() {partNumber = "5678", partPrice = 200.90, partQuantity = 1, partType = "IRREMOVED", partDescription = "test part desc 2"}
                }
            };

            var response = client.getSubmitClaim(null, request);
            var rsp = response.response;
            Console.WriteLine("Status {0}, claim {1}; {2} {3}, {4} errors", rsp.status, rsp.claimNumber,
                rsp.workOrderNumber, rsp.workOrderSegment, rsp.errorsType.Length);
        }

在这一行：

var response = client.getSubmitClaim(null, request);

我一直得到例外：



这是我的web.config

的一部分

  <applicationSettings>
    <TKWarranty.Properties.Settings>
      <setting name="TKWarranty_ThermalKing_getSubmitClaimWSD" serializeAs="String">
        <value>http://data.thermoking.com:443/ws/ThermoKingWebServices.SubmitClaim:getSubmitClaimWSD</value>
      </setting>
    </TKWarranty.Properties.Settings>
  </applicationSettings>

可以找到WSDL文件HERE

当我有Fiddler运行时，我在同一行上收到此错误消息：



有谁知道为什么我会收到此错误？我已在网络配置中确认了端口号。
