在webservice 中使用ArrayList 对象.

经常看到有人在网上问,如何使用WebService中使用ArrayList.其实这是因为没有好好看MSDN的原因.

ArrayList 是一个线性列表对象(它还是有点意思的.),不过WebService不支持其,不是标准变量对象,如果要有WebService中使用得加上属性.??[XmlRoot("根元名")]

例:

______________________序列化的类 YouClass.cs

using System;
using System.Xml.Serialization;

namespace SomeNS

{
?[Serializable]
?[XmlRoot("NewYouClass")]???? //该属性需要加上 xml根元的序列化
?public class YouSerializabledClass
?{
??private long m_lID;

???public YouSerializabledClass()
??{
??}
??public long lID
??{
???get
???{
????return m_lID;
???}
???set
???{
????m_lID=value;
???}
??}

}

______________________________操作YouClass的类 A.cs

[XmlInclude(typeof(YouSerializabledClass))]
??public YouSerializabledClass YouSerializabledClassOperation(Some?Var)
??{
????YouSerializabledClass.lID=Convert.ToInt64(Var);
? ???return YouSerializabledClass;
??}

_______________________ WebMethod

[WebMethod]
??[XmlInclude(typeof(YouSerializabledClass))]
??public? YouSerializabledClass YouWebMetho(SomeVar Var)
??{
???YouSerializabledClass YouSerializabledClass1=A.YouSerializabledClassOperation(Var);
???return YouSerializabledClass ;
??} 这样完了之后,将在客户端产生序列化类的影射.
