从MemoryStream类反序列化XML时，XML文档（27,4）中存在错误

Question

从API接收XML数据时，我会抛出此异常。

{＆＃34;字符串＆＃39;＆＃39;不是有效的AllXsd值。＆＃34;}

XML文档（27,4）中存在错误

XML数据看起来不错，我之前使用过这段代码来解析类似的XML。所以我不确定导致异常的原因。

返回的XML是

<?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">

用于反序列化此XML的代码如下所示：

 var storeXmlInventoryReturnData = returnInventoryData.ReturnValue;

        if (storeXmlInventoryReturnData != null)
        {

            //DeSerialize XML from variable
            agentInventory myInventoryResponse = null;

            XmlSerializer xmlSerializer = new XmlSerializer(typeof(agentInventory));
            MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(storeXmlInventoryReturnData));
            myInventoryResponse = (agentInventory)xmlSerializer.Deserialize(memStream);

            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");
        }

抛出异常的行是

myInventoryResponse = (agentInventory)xmlSerializer.Deserialize(memStream);
