}??調(diào)用方法
List<string> list = new List<string>();
list.Add("192.168.1.1");
list.Add("192.168.3.1");
list.Add("192.168.4.1");
foreach (string s in list)
{
Console.WriteLine(s+" "+ ccPing.PingIp(s));
//if(!xxx)
}
Thread.Sleep(10000);
隔10秒自動(dòng)調(diào)用1次?
?
??檢查URL
public async Task<bool> IsServerRespondingAsync(string url, TimeSpan timeout)
{
try
{
using (var cancellationTokenSource = new System.Threading.CancellationTokenSource())
{
cancellationTokenSource.CancelAfter(timeout);
var response = await _httpClient.GetAsync(url, cancellationTokenSource.Token);
return response.IsSuccessStatusCode;
}
}
catch (TaskCanceledException)
{
// 請(qǐng)求超時(shí)
return false;
}
catch (Exception)
{
// 發(fā)生其他錯(cuò)誤
return false;
}
}?異步調(diào)用
await checker.IsServerRespondingAsync(url, TimeSpan.FromSeconds(2));
如果False可以調(diào)用報(bào)警代碼文章來源：http://www.zghlxwxcb.cn/news/detail-860773.html
