无法反序列化为字符串

Question

我在写一个方法从.xml文件反序列化为对象。我有在XML文件中的内部异常无效的字符串格式字符串从在（7,6）解析为datetime：

<?xml version="1.0" encoding="utf-8"?> 
<Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
<Table>1</Table> 
<OrderInfo> 
    <OrderID>0</OrderID> 
    <OrderType>AtStore</OrderType> 
    <Time>22/12/2014 21:07:44</Time> 
    <RentStatus>Finish</RentStatus> 
    <CancelReason>-</CancelReason> 
    <Cashier>test14</Cashier> 
    <Session>1</Session> 
</OrderInfo> 
<CustomerInfo /> 
<OrderPayment> 
    <PaymentType>Cash</PaymentType> 
    <Total>258</Total> 
    <DiscountPercent>0</DiscountPercent> 
    <Discount>0</Discount> 
    <Payment>258</Payment> 
    <PaymentFromCash>258</PaymentFromCash> 
    <PaymentFromWallet>0</PaymentFromWallet> 
    <Receive>258</Receive> 
    <Exchange>0</Exchange> 
</OrderPayment> 
<OrderDetails> 
    <OrderDetail> 
     <ProductID>107</ProductID> 
     <Code>5</Code> 
     <ProductName>abc</ProductName> 
     <Quantity>1</Quantity> 
     <Price>258</Price> 
     <DiscountPercent>0</DiscountPercent> 
     <Discount>0</Discount> 
     <Total>258</Total> 
     <Payment>258</Payment> 
     <Note /> 
    </OrderDetail> 
</OrderDetails> 

然而，有一个在我的课没有日期时间字段：

public class Order 
{ 
    public OrderInfo OrderInfo { get; set; } 
    public OrderPayment OrderPayment { get; set; } 
    public CustomerInfo CustomerInfo { get; set; } 
    public List<OrderDetail> OrderDetails { get; set; } 
} 
public class OrderInfo 
{ 
    public string OrderID { get; set; } 
    public string OrderOnlineID { get; set; } 
    public int OrderType { get; set; } 
    public string Time { get; set; } 
    public string Note { get; set; } 
    public int RentStatus { get; set; } 
    public string Cashier { get; set; } 
    public string Session { get; set; } 
    public string CancelReason { get; set; } 
} 
public class OrderPayment 
{ 
    public int PaymentType { get; set; } 
    public int Total { get; set; } 
    public int DiscountPercent { get; set; } 
    public int Discount { get; set; } 
    public int Payment { get; set; } 
    public int PaymentFromCash { get; set; } 
    public int PaymentFromWallet { get; set; } 
    public int Receive { get; set; } 
    public int Exchange { get; set; } 
} 
public class OrderDetail 
{ 
    public int ProductID { get; set; } 
    public string Code { get; set; } 
    public string ProductName { get; set; } 
    public int Quantity { get; set; } 
    public int Price { get; set; } 
    public int DiscountPercent { get; set; } 
    public int Total { get; set; } 
    public int Discount { get; set; } 
    public int Payment { get; set; } 

    public OrderDetail() 
    { 
     DiscountPercent = 0; 
     Total = 0; 
     Discount = 0; 
     Payment = 0; 
    } 
} 
public class CustomerInfo 
{ 
    public string CustomerName { get; set; } 
    public string Address { get; set; } 
    public string PhoneNumber { get; set; } 
    public string Email { get; set; } 
} 

这里是我的代码为反序列化：

var serializer = new XmlSerializer(typeof(Order)); 
Order order; 
using (TextReader reader = new StreamReader(filePath)) 
{ 
     order = (Order)serializer.Deserialize(reader); //the exception appears here 
} 

序列化的时候，我还使用一个字符串，不是日期时间。所以我认为这只是将字符串序列化为xml，并将其从xml反序列化为字符串。我不明白为什么发生异常......

我测试你的XML文档，它有几个问题：

下列元素包含字符串数据，但类属性被声明为数值类型：

<OrderType>AtStore</OrderType> 
... 
<RentStatus>Finish</RentStatus> 
... 
<PaymentType>Cash</PaymentType> 

我猜这些应该是枚举？

此外，Order元素未关闭，但我怀疑这只是将XML复制粘贴到问题中的问题。

解决这些问题后，它反序列化好了。
