我想做什么： 我希望我的程序ping服务器以查看它是否已启动。 另外我想要选项勾选一个复选框以进行持久ping。这是Ping每30秒（9999次） 如果我输入的IP地址没有复选框并按回车键，则可以正常工作。 如果我勾选复选框，30秒后，我得到一个成功的ping（假设ping成功），但它从未尝试过第二次。 我认为问题在于for循环中的计时器。 简单来说，我想： - 如果勾选了复选框 然后每30秒进行9999次 - 运行ping方法 - 运行一次 我已经阅读了很多关于此的内容，但是，我已经达到了理解的边缘。我们将非常感激地提供任何帮助/提示！
这是我的代码（我认为计算的位数）
using System.Net.NetworkInformation;
using System.Timers;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media;
namespace PingProject
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
textBoxIPaddress1.KeyDown += textBoxIPaddress1_KeyDown;
}
private void textBoxIPaddress1_KeyDown(object sender, KeyEventArgs e)
{
if (Keyboard.IsKeyDown(Key.Enter))
{
if (every30secs1.IsChecked.Equals(true))
{
for (int pingCount = 0; pingCount < 9999; pingCount++)
{
pingAction1(this, new RoutedEventArgs());
timer = new Timer(30000);
timer.Enabled = true;
timer.Start();
timer.Elapsed += Timer_Elapsed;
}
}
else pingAction1(this, new RoutedEventArgs());
}
}
public static Timer timer;
private void Timer_Elapsed(object sender, ElapsedEventArgs e)
{
timer.Dispose();
}
public void pingAction1(object sender, RoutedEventArgs e)
{
try
{
Ping Ping1 = new Ping();
PingReply pingReply1 = Ping1.Send(textBoxIPaddress1.Text, 1000);
textBoxResponseTime1.Text = (pingReply1.RoundtripTime.ToString() + "ms");
if (pingReply1.Status == IPStatus.Success)
{
successIndicatorRectangle1.Fill = new SolidColorBrush(Color.FromRgb(0, 111, 0));
textBoxError1.Text = ("Successful");
}
else
{
successIndicatorRectangle1.Fill = new SolidColorBrush(Color.FromRgb(222, 0, 0));
textBoxError1.Text = ("Not successful");
}
}
catch
{
textBoxError1.Text = ("Ping operation failed, check IP address or domain name");
successIndicatorRectangle1.Fill = new SolidColorBrush(Color.FromRgb(222, 0, 0));
}
}
private void buttonClear1_Click(object sender, RoutedEventArgs e)
{
successIndicatorRectangle1.Fill = new SolidColorBrush(Color.FromRgb(102, 102, 102));
textBoxError1.Text = (null);
textBoxIPaddress1.Text = (null);
textBoxResponseTime1.Text = (null);
}
}
}

你必须改变你正在做的事情。恕我直言，流程应该是这样的：
在every30secs1.CheckedChanged处理程序上，您必须检查。当复选框转到Checked = true时，您必须使用以下代码激活计时器：
timer.Start();
每当Checked属性更改为false时，则：
timer.Stop();
然后，在你Timer_Elapsed的处理程序上，你必须这样做：
private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
try
{
timer.Stop();
for(int i = 0; i < 9999 ; i++)
{
pingAction1(this, new RoutedEventArgs());
counter ++;
Thread.Sleep(30000);
}
}
catch (Exception ex)
{
//Do something
}
finally
{
timer.Start();
}
}
