使用线程处理 例如
private void button6_Click(object sender, System.EventArgs e)
{
Thread cmdthread = new Thread(new ThreadStart(this.ThreadCmd));
cmdthread.IsBackground = true;
cmdthread.Start();
}
private void ThreadCmd()
{
int i=1;
for(i=1;i<254;i++)
{
string pstr="192.168.0."+i.ToString();
string strRst = CmdPing(pstr);
listBox1.Items.Add(pstr+"___"+strRst);
}
}
private static string CmdPing(string strIp)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
string pingrst;
p.Start();
p.StandardInput.WriteLine("ping -n 1 "+strIp);
p.StandardInput.WriteLine("exit");
string strRst = p.StandardOutput.ReadToEnd();
if(strRst.IndexOf("(0% loss)")!=-1)
pingrst = "连接";
else if( strRst.IndexOf("Destination host unreachable.")!=-1)
pingrst = "无法到达目的主机";
else if(strRst.IndexOf("Request timed out.")!=-1)
pingrst = "超时";
else if(strRst.IndexOf("Unknown host")!=-1)
pingrst = "无法解析主机";
else
pingrst = strRst;
p.Close();
return pingrst;
