导读：我们需要在XML与实体类，DataTable，List之间进行转换，下面是XmlUtil类，该类来自网络并稍加修改。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 5

我们需要在XML与实体类，DataTable，List之间进行转换，下面是XmlUtil类，该类来自网络并稍加修改。

下面是测试代码：

1. 实体对象转换到Xml

 
        9 
        
      Student 
        
        { 
       
         Name {  
        set 
        ;  
        get 
        ; } 
       
         int 
         Age {  
        ; } 
       
        } 
       
        Student stu1 =  
         Student() { Name =  
        "okbase" 
        ,Age = 10 }; 
       
         xml = XmlUtil.Serializer( 
        typeof 
        (Student),stu1); 
       
        Console.Write(xml);

2.Xml转换到实体对象

 
        Student stu2 = XmlUtil.Deserialize( 
        as 
         Student; 
       

 
        Console.Write( 
        .Format( 
        "名字:{0},年龄:{1}" 
        3.DataTable转换到Xml
 
        18 
        
        // 生成DataTable对象用于测试 
       
        DataTable dt1 =  
         DataTable( 
        "mytable" 
        );  
        // 必须指明DataTable名称 
       
        dt1.Columns.Add( 
        "Dosage" 
        ( 
        int 
        )); 
       
        "Drug" 
        )); 
       
        "Patient" 
        )); 
       
        "Date" 
        (DateTime)); 
       
        // 添加行 
       
        dt1.Rows.Add(25, 
        "Indocin" 
        "David" 
         
        dt1.Rows.Add(50,monospace!important; font-size:1em!important; min-height:inherit!important; color:blue!important">"Enebrel" 
        "Sam" 
         
        dt1.Rows.Add(10,monospace!important; font-size:1em!important; min-height:inherit!important; color:blue!important">"Hydralazine" 
        "Christoff" 
         
        dt1.Rows.Add(21,monospace!important; font-size:1em!important; min-height:inherit!important; color:blue!important">"Combivent" 
        "Janet" 
         
        dt1.Rows.Add(100,monospace!important; font-size:1em!important; min-height:inherit!important; color:blue!important">"Dilantin" 
        "Melanie" 
        
        // 序列化 
       
        xml = XmlUtil.Serializer( 
        (DataTable),dt1); 
       
        Console.Write(xml); 
       
4.Xml转换到DataTable
 
        13 
        
     // 反序列化 
        
        DataTable dt2 = XmlUtil.Deserialize( 
         DataTable; 
       
        // 输出测试结果 
       
        foreach 
         (DataRow dr  
        in 
         dt2.Rows) 
       
        { 
       
         (DataColumn col  
         dt2.Columns) 
       
        { 
       
        Console.Write(dr[col].ToString() +  
        " " 
        ); 
       
        } 
       
        Console.Write( 
        "rn" 
        ); 
       
        } 
       
5.List转换到Xml
 
        8 
        
     // 生成List对象用于测试 
        
        List<Student> list1 =  
         List<Student>(3); 
       
        list1.Add( 
         
        "csdn" 
         
        // 序列化 
       
        (List<Student>),list1); 
       
        Console.Write(xml); 
       
6.Xml转换到List
 
        5 
        
     List<Student> list2 = XmlUtil.Deserialize( 
         List<Student>; 
         (Student stu  
         list2) 
       
        { 
       
        Console.WriteLine(stu.Name +  
        "," 
         + stu.Age.ToString()); 
       
        } 
       
从代码可以看到，千变万化不离其宗!
