单线程IP扫描解析

扫描代码：

private void Button_Click(object sender, RoutedEventArgs e)

{

a5.Items.Clear();

string str = this.a1.Text;

int start = int.Parse(a2.Text);

int end = int.Parse(a3.Text);

Stopwatch sw = new Stopwatch();

sw.Start();

for (int i = start; i < end+1; i++)

{

sw.Start();

string str1 = str + i.ToString();

string strHostName = "";

try

{

IPHostEntry ip = Dns.GetHostEntry(str1);

strHostName = ip.HostName;

sw.Stop();

a5.Items.Add("扫描地址："+str1+"扫描时间:"+sw.ElapsedMilliseconds+"毫秒   "+"主机DNS名称:"+strHostName);

}

catch (Exception ex)

{

a5.Items.Add("扫描地址：" + str1 + "扫描时间:" + sw.ElapsedMilliseconds + "毫秒   " + "主机DNS名称:" + "(不在线)");

}

}

动态监测：

private void a2_TextChanged(object sender, TextChangedEventArgs e)

{

string ss = a1.Text + a2.Text;

try

{

IPAddress p = IPAddress.Parse(ss);

a4.Content = "";

}

catch (Exception ex)

{

a4.Content = "                                               ip地址有错，请更正";

}

}

private void a3_TextChanged(object sender, TextChangedEventArgs e)

{

string ss = a1.Text + a3.Text;

try

{

IPAddress p = IPAddress.Parse(ss);

a4.Content = "";

}

catch (Exception ex)

{

a4.Content = "                                             ip地址有错，请更正";

}

}
