紧急，应用程序调用webservice时出的问题

[mao642]

我的webservice如下:

public string ID="";

....

[WebMethod(EnableSession=true)]
public string GetID()
{
return this.ID;
}
[WebMethod(EnableSession=true)]
public void SetID(string str)
{
this.ID = str;
}

...

用asp.net调用它的时候,
myService.SetID("hehe")
则myService.GetId() == "hehe

而在用c#写的应用程序客户端如此调用
myService.SetID("hehe");
string str myService.GetId();

则str==null

请教达人,不知什么原因啊~~~

ID是什么?

return Session["ID"].ToString(); 试试

注意，每次连接要重新构造一次

用Session["ID"].ToString(),

[saucer]

everytime you call a webmethod, a new instance of the webservice class is created, try the following


//public string ID="";

public string ID
{
get
{
if (Session["ID"] == null)
return "";
return (string)Session["ID"];
}
set
{
Session["ID"] = value;
}
}

[WebMethod(EnableSession=true)]
public string GetID()
{
return this.ID;
}
[WebMethod(EnableSession=true)]
public void SetID(string str)
{
this.ID = str;
}


don't forget to create a CookieContainer for your client side proxy object:

myService.CookieContainer = new CookieContainer();
myService.SetID("hehe");
string str = myService.GetId();

you might need to replace Session with System.Web.HttpContext.Current.Session if your class is not derived from WebService class
