小编use*_*190的帖子

这一切都是在一小时前和很多天前完成的.我尝试ping的链接是:

链接到ping

这是form1中的代码:

nc = new NetworkConnection();
bool bval = nc.PingConnection(satellite_address);

if (bval)
{
    label19.Visible = true;
    label19.Text = "Internet Access";
}
else
{
    label19.Visible = true;
    label19.Text = "No Internet Access";
}

当它试图执行此行时:

bool bval = nc.PingConnection(satellite_address);

它会nc上课:

        }

        public bool PingConnection(string url)
        {
            bool Result = false;

            using (Ping pp = …

Directory.CreateDirectory(@"c:\temp\newimages\" + "SecondProcess_" +
                    DateTime.Now);

我想要创建的是c:\ temp \newimages \中的目录.例如:

C:\ TEMP \newimages\SecondProcess_5/13/2014-2:33
