下面是测试代码：
1. 实体对象转换到Xml

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

2. Xml转换到实体对象
|

Student stu2 = XmlUtil.Deserialize(
typeof
(Student), xml)
as
Student;
Console.Write(
string
.Format(
"名字:{0},年龄:{1}"
, stu2.Name, stu2.Age));
|
3. DataTable转换到Xml

// 生成DataTable对象用于测试
DataTable dt1 =
new
DataTable(
"mytable"
);
// 必须指明DataTable名称
dt1.Columns.Add(
"Dosage"
,
typeof
(
int
));
dt1.Columns.Add(
"Drug"
,
typeof
(
string
));
dt1.Columns.Add(
"Patient"
,
typeof

,
typeof

// 添加行
dt1.Rows.Add(25,
"Indocin"

dt1.Rows.Add(100,
"Dilantin"
,

// 输出测试结果
foreach

list1.Add(
new
Student() { Name =
"csdn"
, Age = 15 });
// 序列化
xml = XmlUtil.Serializer(
typeof
