根据xsd序列化与反序列化xml

1，建立xsd

step1：建立“类型”Version、Updatetime，Files，File

step2：建立Files与File的多对一关系，添加Files中的file引用（是File类型的），修改file的属性maxOccurs为unbounded，minOccurs为1

如图：

step3：建立顶级元素“类型”Update，添加version，updatetime，files的引用，如图

step4：添加顶级元素update（类型为Update），如图

xsd代码如下：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="UpdateFile" targetNamespace="http://tempuri.org/UpdateFile.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/UpdateFile.xsd" xmlns:mstns="http://tempuri.org/UpdateFile.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:complexType name="Update">
        <xs:sequence>
            <xs:element name="version" type="Version" />
            <xs:element name="updatetime" type="Updatetime" />
            <xs:element name="files" type="Files" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="Version">
        <xs:sequence>
            <xs:element name="value" type="xs:string" />
            <xs:element name="type" type="xs:string" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="Updatetime">
        <xs:sequence>
            <xs:element name="value" type="xs:dateTime" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="Files">
        <xs:sequence>
            <xs:element name="file" type="File" maxOccurs="unbounded" minOccurs="1" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="File">
        <xs:sequence>
            <xs:element name="url" type="xs:string" />
        </xs:sequence>
    </xs:complexType>
    <xs:element name="update" type="Update">
    </xs:element>
</xs:schema>

2，生成实体类

用vs命令行在项目文件夹下输入以下命令

xsd.exe 要生成实体类的.xsd /c /namespace:要生成的实体类的命名空间

3，两个静态工具类

class Common
        {
                /// <summary>
                /// 将XML文件写入指定的对象
                /// </summary>
                /// <param name="xmlFile">xml绝对路径</param>
                /// <param name="type">序列的类型,要与XML对应的类</param>
                /// <returns>将对象返回,当文件操作失败则返回Null值</returns>
                public static object DeserializeXmlToObject(string xmlFile, Type type)
                {
                        XmlSerializer mySerializer = new XmlSerializer(type);
                        using (FileStream stream = new FileStream(xmlFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
                        {
                                return mySerializer.Deserialize(stream);
                        }
                }

                /// <summary>
                ///    将对象写入到XML中
                /// </summary>
                /// <param name="obj">数据源对象</param>
                /// <param name="xmlFile">目标路径</param>
                /// <param name="type">转换类型</param>
                public static void SerializeObjectToXml(object obj, String xmlFile, Type type)
                {
                        XmlSerializer mySerializer = new XmlSerializer(type);
                        using (FileStream stream = new FileStream(xmlFile, FileMode.Create, FileAccess.Write, FileShare.Read))
                        {
                                mySerializer.Serialize(stream, obj);
                        }
                }
        }

4，序列化与反序列化

//反序列化
                                Update a = new Update();
                                a.version = new Version();
                                a.version.type = "0";
                                a.version.value = "1.0.0.0";
                                a.updatetime = new Updatetime();
                                a.updatetime.value = new System.DateTime();
                                a.files = new File[1];
                                a.files[0] = new File();
                                a.files[0].url = "http://test.exe";
                                Common.SerializeObjectToXml(a, "目标.xml", typeof(Update));

                                //系列化
                                Update u = (Update)Common.DeserializeXmlToObject("目标.xml", typeof(Update));
