问如何使用特定的网络接口(或特定的源IP地址)执行Ping操作？

EN

i know this is a old question but i found a solution and want to share it.

public static PingReply Send(IPAddress srcAddress, IPAddress destAddress, int timeout = 5000, byte[] buffer = null, PingOptions po = null)

    var sendbuffer = buffer ?? new byte[] {};
    var options = new Interop.Option
    {
        Ttl = (po == null ? (byte) 255 : (byte) po.Ttl),
        Flags = (po == null ? (byte) 0 : po.DontFragment ? (byte) 0x02 : (byte) 0) //0x02
    };
    var fullReplyBufferSize = Interop.ReplyMarshalLength + sendbuffer.Length; //Size of Reply struct and the transmitted buffer length.

 

    var allocSpace = Marshal.AllocHGlobal(fullReplyBufferSize); // unmanaged allocation of reply size. TODO Maybe should be allocated on stack
