Ping IP——一次还是多次？

Question

我正在使用下面的代码来 ping IP 地址并检查它是否在线。现在只想知道，这个 C# 的 ping.Send(ipAddress) 只会执行 1 次还是 3 次？

Ping ping = new Ping();
PingReply pingReply = ping.Send(ipAddress);

if (pingReply.Status == IPStatus.Success)
{
    // Proceed as normal.
}
else
{
    // Send email to Admin.
}

Answer 1

一次调用 ping.Send 将发送一个 ICMP 数据包。 the documentation 中没有任何内容表示进行了多次尝试：

Attempts to send an Internet Control Message Protocol (ICMP) echo message to the specified computer, and receive a corresponding ICMP echo reply message from that computer.

Answer 2

它会像方法描述中所说的那样执行一次 ping。

Attempts to send an Internet Control Message Protocol (ICMP) echo message with the specified data buffer to the computer that has the specified IPAddress, and receive a corresponding ICMP echo reply message from that computer. This method allows you to specify a time-out value for the operation.
