Question

我使用priceResponse.cs从xml生成xsd文件，然后从xsd文件生成xsd.exe。

以下是priceResponse.cs代码：

using System.Xml.Serialization;

我正在尝试反序列化priceResponse.xml，但似乎它被卡住了。我认为名称空间存在问题，而且我正在进行反序列化错误。

这是xml代码：

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<document>
    <DATASETS>
        <COUNTRY>UTD</COUNTRY>
        <CURRENCY>UTD</CURRENCY>
        <POSTCODEMASK>UTD</POSTCODEMASK>
        <TOWNGROUP>UTD</TOWNGROUP>
        <SERVICE>UTD</SERVICE>
        <OPTION>UTD</OPTION>
    </DATASETS>
    <ERROR>
        <CODE>P13</CODE>
        <DESCRIPTION>RATEID: 1 - Standard Rates</DESCRIPTION>
    </ERROR>
    <PRICE>
        <RATEID>1</RATEID>
        <SERVICE>09N</SERVICE>
        <SERVICEDESC>9:00 Express</SERVICEDESC>
        <OPTION>NONE</OPTION>
        <OPTIONDESC>NONE</OPTIONDESC>
        <CURRENCY>PLN</CURRENCY>
        <RATE>712.93</RATE>
        <RESULT>Y</RESULT>
    </PRICE>
    <PRICE>
        <RATEID>1</RATEID>
        <SERVICE>10N</SERVICE>
        <SERVICEDESC>10:00 Express</SERVICEDESC>
        <OPTION>NONE</OPTION>
        <OPTIONDESC>NONE</OPTIONDESC>
        <CURRENCY>PLN</CURRENCY>
        <RATE>706.14</RATE>
        <RESULT>Y</RESULT>
    </PRICE>
    <PRICE>
        <RATEID>1</RATEID>
        <SERVICE>12N</SERVICE>
        <SERVICEDESC>12:00 Express</SERVICEDESC>
        <OPTION>NONE</OPTION>
        <OPTIONDESC>NONE</OPTIONDESC>
        <CURRENCY>PLN</CURRENCY>
        <RATE>689.84</RATE>
        <RESULT>Y</RESULT>
    </PRICE>
    <PRICE>
        <RATEID>1</RATEID>
        <SERVICE>15N</SERVICE>
        <SERVICEDESC>Express</SERVICEDESC>
        <OPTION>NONE</OPTION>
        <OPTIONDESC>NONE</OPTIONDESC>
        <CURRENCY>PLN</CURRENCY>
        <RATE>670.03</RATE>
        <RESULT>Y</RESULT>
    </PRICE>
</document>

最后反序列化代码：

File.WriteAllText("priceResponse.xml", x);
//Console.WriteLine(x);

var ser = new XmlSerializer(typeof(document),new XmlRootAttribute("documentPRICE"));
using (var reader = XmlReader.Create("priceResponse.xml"))
{
    var wrapper = (document)ser.Deserialize(reader);

    foreach (documentPRICE item in wrapper.Items)
    {
        Console.WriteLine(item.OPTIONDESC);
    }
}

我想在PRICE元素中获取每个项目，但我无法反序列化xml。我究竟做错了什么？

Answer 1

在这行代码中，

var ser = new XmlSerializer(typeof(document),new XmlRootAttribute("documentPRICE"));

您已经序列化了文档对象，但是将xml的根保持为documentPRICE。在这里，

var wrapper = (document)ser.Deserialize(reader);

您正在尝试将其反序列化为document对象，这是没有意义的。在您的案例中序列化后创建的xml具有documentPRICE作为根对象，但您尝试将相同的序列反序列化为document对象，这是错误的。您需要做的是在序列化时将document作为根目录，如下所示。

var ser = new XmlSerializer(typeof(document), new XmlRootAttribute("document"));

它应该有用。
