我想要一個類被序列化爲XML。 它的工作原理,但字符串屬性「origen」是全部序列化爲字符串,也是空的時候。 我想串行避免包括它的XML裏面當它是空XmlSerialization忽略字符串屬性如果爲空
類是FirmaElement,例如:
FirmaElement firma= new FirmaElement();
firma.Value="HITHERE";
firma.origen=String.Empty;
預期的結果
string x= Serialize(FirmaElement);
x="<Firma>HITHERE</Firma>";
FirmaElement firma= new FIrmaElement();
firma.Value="HITHERE";
firma.origen="OK";
預期成果
string x= Serialize(FirmaElement);
x="<Firma origen='ok'>HITHERE</Firma>";
代碼
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://gen/ces/headers/CesHeader")]
[System.Xml.Serialization.XmlRoot("Firma")]
public class FirmaElement
{
public FirmaElement() { }
string _origen = String.Empty;
string _value = String.Empty;
[System.Xml.Serialization.XmlAttributeAttribute()]
public string origen
{
get { return _origen; }
set { _origen = value; }
}
[System.Xml.Serialization.XmlTextAttribute()]
public string Value
{
get { return _value; }
set { _value = value; }
}
public override string ToString()
{
return this.Value;
}
//IS THIS CORRECT? SHould i override something??
public string Serialize()
{
XmlAttributeOverrides xOver = new XmlAttributeOverrides();
XmlAttributes attrs = new XmlAttributes();
/* Setting XmlIgnore to false overrides the XmlIgnoreAttribute
applied to the Comment field. Thus it will be serialized.*/
attrs.XmlIgnore = String.IsNullOrEmpty(origen);
xOver.Add(typeof(string), "origen", attrs);
I DONT KNOW WHAT TO PUT HERE, IT'S CORRECT??
//XmlSerializer xSer = new XmlSerializer(typeof(XmlTypeAttribute), xOver);
}
}
顯示沒有值的屬性origen有什麼危害? XML被設計爲處理數據格式,提供或不提供值。 –
