XML 2020-05-25

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。

/// <summary>

static object Deserialize(Type type, string xml)
{
try
{
(StringReader sr = new StringReader(xml))
{
XmlSerializer xmldes = XmlSerializer(type);
return xmldes.Deserialize(sr);
}
}
catch (Exception e)
{
return null ;
}
}
/// <summary>

XmlSerializer(type);
xmldes.Deserialize(stream);
}

string Serializer(Type type,153)!important">object obj)
{
MemoryStream Stream = MemoryStream();
XmlSerializer xml = XmlSerializer(type);
try
{
//序列化对象
xml.Serialize(Stream,obj);
}
(InvalidOperationException)
{
throw ;
}
Stream.Position = 0;
StreamReader sr = StreamReader(Stream);
str = sr.ReadToEnd();
sr.Dispose();
Stream.Dispose();
str;
}
#endregion
}

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

2
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( "\r\n" );
}

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!
