在另外一个页面中实例化时出错，出错信息如下 ：

c:\inetpub\wwwroot\HOHO\WebForm1.aspx.cs(50): 重载“mailsend”方法未获取“8”参数

localhost.mailsend objs = new HOHO.localhost.mailsend("admin","1","1","1","1","1","1","1");//就是这句报错！！

[孟子E章]

localhost.mailsend objs = new HOHO.localhost.mailsend();
objs.mailsend("admin","1","1","1","1","1","1","1");

[softchao]

NoxMailService.mailsend objs = new NoxMailService.mailsend();
objs.mailsend("admin","1","1","1","1","1","1","1");

webservice中不能重载构造函数吗？？？哪我该如何给类中的属性赋值呢？？？

[ldw701]

事实上只有这一个是webservice提供的方法！
[WebMethod]
public string MailSend()
{
return this.password;
}

[xiaobo]

可以这样：
先定义
class Mail
{
private string From;
private string To;
private string Subject;
....
}

[WebService(Namespace="Hello",Description="在Web Services里发送邮件。")]
public class mailsend : System.Web.Services.WebService
{
[WebMethod]
public string MailSend(Mail mail)
{
processMail(mail);
return mail.password;
}
}

class test
{
public static void main()
{
Mail mail = new Mail(...);
mailsend

}
}

[greystar]

不要使用构造函数

[greystar]

在方法里添加参数列表.
