C# 如何反序列化xml中包含列表的xmlelement
我正在使用silverlight5和c#来实现我的目标。我有以下xml文件:C# 如何反序列化xml中包含列表的xmlelement,c#,xml,deserialization,xml-deserialization,C#,Xml,Deserialization,Xml Deserialization,我正在使用silverlight5和c#来实现我的目标。我有以下xml文件: string xmlstring = <?xml version="1.0" encoding="utf-8" ?> <parameter> <name>bands_amounts</name> <label>Bands Amounts</label> <unit></unit> <component
string xmlstring =
<?xml version="1.0" encoding="utf-8" ?>
<parameter>
<name>bands_amounts</name>
<label>Bands Amounts</label>
<unit></unit>

及
因为这个包含“1 000 000”、“5 000 000”等的“项目”在“属性”内?请解释我是初学者使用下面的代码,您可以序列化和反序列化您的对象,即使您可以存储xml
SerializeObject(objDividendList, filename);
objDividendList=反序列化对象>(文件名)
public void serialized对象(T serializableObject,字符串文件名)
{
如果(serializableObject==null){return;}
尝试
{
XmlDocument XmlDocument=新的XmlDocument();
XmlSerializer serializer=新的XmlSerializer(serializableObject.GetType());
使用(MemoryStream stream=new MemoryStream())
{
serializer.Serialize(流,serializableObject);
流位置=0;
加载(流);
xmlDocument.Save(文件名);
stream.Close();
}
}
捕获(例外情况除外)
{
//此处记录异常
log.Error(“序列化对象”,ex);
}
}
公共T反序列化对象(字符串文件名)
{
if(string.IsNullOrEmpty(fileName)){返回默认值(T);}
T objectOut=默认值(T);
尝试
{
string attributeXml=string.Empty;
XmlDocument XmlDocument=新的XmlDocument();
加载(文件名);
字符串xmlString=xmlDocument.OuterXml;
使用(StringReader读取=新的StringReader(xmlString))
{
类型outType=类型of(T);
XmlSerializer serializer=新的XmlSerializer(outType);
使用(XmlReader=新的XmlTextReader(读取))
{
objectOut=(T)序列化程序。反序列化(读取器);
reader.Close();
}
read.Close();
}
}
捕获(例外情况除外)
{
//此处记录异常
log.Error(“反序列化对象”,ex);
}
退出;
}
谢谢你的回答,但你读过我的问题了吗?我已经序列化了我的xml并将其放在字符串“xmlstring”中,问题是当我调试“Debug.WriteLine(attrib.item);”时,我无法看到“1000 000”、“5000 000”等。为什么?而在执行“Debug.WriteLine(attrib.type);”时,会显示“List”(表示为其工作)。如何查看我想要查看的内容?另外,当我尝试查看“Debug.WriteLine(attrib.ccypair);”时,“ccypair”显示为null。请再次查看问题。我已经应得了。我需要这些值,因为在我必须创建对应于这个列表值“1000000”等的GUI之后,我需要这样做吗?“[XmlArray(“组件”)、XmlArrayItem(“属性”、typeof(属性))]公共列表组件{get{return(_attributes)}set{u attributes=value;}}}”你有什么建议?“10000000”、“5000000”和“10000000”是字符串值而不是整数<代码>属性。项目声明为int
@rageit thaks,我正在更正它。它甚至可以这样做吗?为什么它在调试时将“ccypair”显示为空值。@rageit我需要这样做吗?“[XmlArray(“组件”)、XmlArrayItem(“属性”、typeof(属性))]公共列表组件{get{return(_attributes)}set{u attributes=value;}}”你有什么建议?如果你想要像“10000000”、“5000000”和“10000000”这样的字符串为了与整数值100、500和1000一起考虑,我建议将item
类型从List
更改为List
