当整数值正常工作时,十进制字段不被反序列化

示例Xml:

<TestXML>
   <TestDecimal attr1="Required" attr2="false">0.34</TestDecimal>
   <TestInteger attr1="MyAttr" attr2="1" DateAdded="">25</TestInteger>
</TestXML>

班级定义:

public class TestXML {
   public DecimalValue TestDecimal;
   public IntegerValue TestInteger;
}

public class IntegerValue {
   [XmlText]
   public int value {get; set;}
   [XmlAnyAttribute]
   public XmlAttribute[] XAttributes {get; set;}
}
public class DecimalValue {
   [XmlText]
   public decimal value {get; set;}
   [XmlAnyAttribute]
   public XmlAttribute[] XAttributes {get; set;}
}

反序列化代码:

XmlSerializer serializer = new XmlSerializer(typeof(TestXML));
using (FileStream fs = new FileStream(@"C:\Test.xml", FileMode.Open)) {
   TestXML myxml = (TestXML)serializer.Deserialize(fs);
}

在测试中,它返回整数值但不是十进制值:

myxml
   TestDecimal
      value |  0
      XAttributes  {string[2]}
         [0] Name="attr1", Value="Required"
         [1] Name="attr2", Value="false"
   TestInteger
      value |  25
      XAttributes  {string[3]}
         [0] Name="attr1", Value="MyAttr"
         [1] Name="attr2", Value="1"
         [2] Name="DateAdded", Value=""

是否有关于反序列化小数的内容会导致它返回0?使用十进制的原始类型,十进制值返回正常。

1 个答案:

答案 0 :(得分:2)

您必须在实际代码中执行与此处显示的内容不同的操作。您的代码不会像已发布的那样编译 - 特别是类定义在C#中的名称之后没有()。

这对我来说符合预期(十进制值得到正确的反序列化):

using System;
using System.Diagnostics;
using System.Net;
using System.Net.Sockets;
using System.Xml;
using System.Xml.Serialization;
using System.IO;

namespace Test
{

    public class TestXML
    {
        public DecimalValue TestDecimal;
        public IntegerValue TestInteger;
    }

    public class IntegerValue
    {
        [XmlText]
        public int value {get; set;}
        [XmlAnyAttribute]
        public XmlAttribute[] XAttributes {get; set;}
    }

    public class DecimalValue
    {
        [XmlText]
        public decimal value {get; set;}
        [XmlAnyAttribute]
        public XmlAttribute[] XAttributes {get; set;}
    }

    class Program
    {

        static void Test()
        {
            XmlSerializer serializer = new XmlSerializer(typeof(TestXML));
            using (FileStream fs = new FileStream("Test.xml", FileMode.Open)) 
            {
                TestXML myxml = (TestXML)serializer.Deserialize(fs);
            }

        }

        static void Main(string[] args)
        {
            Test();
        }
    }
}

将本地test.xml文件复制到包含此数据的bin目录:

<TestXML>
    <TestDecimal attr1="Required" attr2="false">0.34</TestDecimal>
    <TestInteger attr1="MyAttr" attr2="1" DateAdded="">25</TestInteger>
</TestXML>
