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.

public YouSerializabledClass YouWebMetho(string EPID) {

return ((YouSerializabledClass )(results[0]));
}

public System.IAsyncResult BeginYouWebMetho(SomeVar Var, System.AsyncCallback callback, object asyncState) {
return this.BeginInvoke("BeginYouWebMetho", new object[] {
Var}, callback, asyncState);
}

/// <remarks/>
public YouSerializabledClass EndGetYouWebMetho(System.IAsyncResult asyncResult) {
object[] results = this.EndInvoke(asyncResult);
return ((YouSerializabledClass )(results[0]));
}

/// <remarks/>
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")]
public class YouSerializabledClass {

/// <remarks/>
public long lID;
} 这就是你产生的序列化类.
