C# Ping IP Address RRS feed

  • Question

  • string copyFiles;
                copyFiles = "\\\\" + ipAddress.Text;
    
                Ping ping = new Ping();
                PingReply reply = ping.Send(ipAddress.Text, 1000);
                if (reply.Status == IPStatus.Success)
                {
                    this.statusMsg.Text = "Files were successfuly copied to users Desktop";
                }
                Else 
                {
                    this.statusMsgFail.Text = "Failed, files were not copied";
                }

    The script above works when the ip address is correct or not responding, i get a random error message if it is not either of them.  For example: if I enter a space "321351 " the sends me back an error message

    I get the following error message

    System.Net.NetworkInformation.PingException: 'An exception occurred during a Ping request.'

    SocketException: No such host is known

    at

        PingReply reply = ping.Send(ipAddress.Text, 1000);

  • Hi mucubac,

    Thank you for posting here.

    According to your description, you want to solve the exception you got when you enter a space "32151" to the textbox. Also, I get the same error with you.

    Based on my search, I find Ping.Send(String, Int32) method has some limit about the parameter 'string'.

    A String that identifies the computer that is the destination for the ICMP echo message. The value specified for this parameter can be a host name or a string representation of an IP address.

    Therefore, you may meet the error when you use "321351 ".

    Hope my explanation could be helpful.

    Best Regards,

    Jack
