InnerException：將字符串轉換為DateTime時。 在將每個變量放入DateTime對象之前，分析字符串以對日期進行日期解析

Question

我正在嘗試反序列化從API調用返回的XML，但得到的是“ InnerException：將字符串轉換為DateTime時。在將每個變量放入DateTime對象之前，分析字符串的日期為日期”

XML看起來像這樣

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<agentInventory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:N1="demo.org.uk/demo/CustomsStatus" xmlns:N2="demo.org.uk/demo/UnLocation" xmlns:N3="demo.org.uk/demo/AirCarrier" xmlns="demo.org.uk/demo/AgentInventory">
  <shed>ADX</shed>
  <arrivalPort>
    <N2:iataPortCode>LHR</N2:iataPortCode>
      </arrivalPort>
  <masterAirwayBillPrefix>125</masterAirwayBillPrefix>
  <masterAirwayBillNumber>28121101</masterAirwayBillNumber>
  <nominatedAgent>DRB</nominatedAgent>
  <originPort>
   <N2:iataPortCode>BOS</N2:iataPortCode>
  </originPort>
  <destinationPort>
    <N2:iataPortCode>LHR</N2:iataPortCode>
  </destinationPort>
  <airCarrier>
    <N3:carrierCode>BA</N3:carrierCode>
  </airCarrier>
  <flightNumber>235</flightNumber>
  <flightDate>2012-02-09T00:00:00Z</flightDate>
  <npx>10</npx>
  <npr>0</npr>
 <grossWeight>123.0</grossWeight>

  <sdc>T</sdc>
  <status1Set></status1Set>
  <status2Set>false</status2Set>
  <ccsCreationTime></ccsCreationTime>
  <customsSummaryText />
  <customsSummaryTime></customsSummaryTime>
  <agentReference />
  <isErtsPreArrival>false</isErtsPreArrival>
  <isAgentPreArrival>false</isAgentPreArrival>
  <isDeleted>false</isDeleted>
  <finalised></finalised>
  <createdOn>2012-01-24T11:50:40.86Z</createdOn>
  <modifiedOn>2012-02-09T09:51:26.617Z</modifiedOn>
  </agentInventory>

用於反序列化XML的代碼是

 if (storeXmlInventoryReturnData != null)
        {

            //DeSerialize XML from storeXmlInventoryReturnData variable
            agentInventory myInventoryResponse = null;

           XmlSerializer xmlSerializer = new XmlSerializer(typeof(agentInventory));                             
          myInventoryResponse =  (
               agentInventory)xmlSerializer.Deserialize(new StringReader(storeXmlInventoryReturnData)

               );

            Console.WriteLine(
             @"\n\n\n INVENTORY RETURN DATA FOR AWB: {0}-{1} \n\n 
                          Destination Port: {2} \n 
                          Arrival Port: {3} \n 
                          Carrier: {4} \n 
                          Flight No: {5} \n 
                          Flight Date: {6} \n 
                          Customers Status: {7} \n 
                          NPX: {8} \n
                          NPR {9} \n
                          SDC Code: {10}                              
                          \n\n Hit any key to exit...."
                ,

                myInventoryResponse.masterAirwayBillPrefix,
               myInventoryResponse.masterAirwayBillNumber,
                myInventoryResponse.destinationPort,
                myInventoryResponse.arrivalPort,
                myInventoryResponse.airCarrier,
                myInventoryResponse.flightNumber,
               myInventoryResponse.flightDate,
               myInventoryResponse.customsStatus,
                myInventoryResponse.npx,
                myInventoryResponse.npr,
                myInventoryResponse.sdc,
               myInventoryResponse.grossWeight,
                myInventoryResponse.goodsDescription
                    );
            Console.ReadLine();
        }
        else
        {
            Console.Write("No data returned");
        }

    }

拋出異常。 myInventoryResponse =（agentInventory）xmlSerializer.Deserialize（new StringReader（storeXmlInventoryReturnData））;

我想我需要將myInventoryResponse.flightDate轉換為DateTime對象，但我無所適從如何實現這一目標？

為了我自己的頭腦，我嘗試使提供的XML與您的類和可為null的DateTime字段一起使用。

為了使它們起作用，請用以下鏈接的屬性替換以下屬性。 DateTime對象的默認值為DateTime.MinDate ，因此，如果傳入的值為null或為空，則該屬性將始終具有DateTime.MinDate的值，為此，如果您的代碼需要執行以下操作，則可能需要進行其他驗證/更改：迎合這一點。

      return status1Set;
    }

      XmlNode[] inputValue = value as XmlNode[];
      if (inputValue != null)
