[Asp.Net] Pinging using asp.net

要使用ping類別之前，需引入using System.Net.NetworkInformation;

public class SitePinged : System.Web.Services.WebService {

    public SitePinged () {

        //如果使用設計的元件，請取消註解下行程式碼 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string Ping(string site)
    {
        Ping wsPing = new Ping();
        PingReply wsPingReply = wsPing.Send(site);
        return wsPingReply.Status.ToString();
    }
    
}
