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
        {
                 ///

                 /// 将XML文件写入指定的对象
                 ///

                 /// "xmlFile">xml绝对路径
                 /// "type">序列的类型,要与XML对应的类
                 /// 将对象返回,当文件操作失败则返回Null值
                 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);
                        }
                }

                 ///

                 ///    将对象写入到XML中
                 ///

                 /// "obj">数据源对象
                 /// "xmlFile">目标路径
                 /// "type">转换类型
                 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));
