后台工作器和进度条不能正常工作

我试图有一个进度条加载我的加密和压缩应用程序。我试图使用后台工作器来更新进度条所花费的时间进行压缩和加密处理，但不知何故，应用程序显示加密失败的消息框，我已经包含在按钮内，而不是一个成功。

这是我的按钮的代码

    private void lockButton_Click(object sender, EventArgs e)
    {
        if (this.passwordtextBox.Text == "")
        {
            MessageBox.Show("Please enter a password!");
        }
        else if (this.retypeTextBox.Text == "")
        {
            MessageBox.Show("Please retype password!");
        }
        else if (this.passwordtextBox.Text == this.retypeTextBox.Text)
        {
            details = new Details();
            details.SetPassword(this.passwordtextBox.Text);
            if (this.EncryptionComboBox.Text == "AES")
            {
                details.SetEncryption(this.EncryptionComboBox.Text);
                if (details.GetResult() == true)
                {
                    // Start the background worker
                    backgroundWorker1.RunWorkerAsync();
                }
                if (details.GetResult() == true)
                {
                    MessageBox.Show("Lock Success!");
                }
                else
                {
                    MessageBox.Show("Lock Unsuccess! Please try again");
                }
            }
        }
        else
        {
            MessageBox.Show("The password and verified password does not match!");
        }
    }

这是我的后台工作代码

    private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        //declare lockcontroller to be used
        LockController lControl = new LockController();
        //run zipfile method and store result to fName
        lControl.compress(ifile, details);
        lControl.Encrypt(details);
        lControl.LockCleaner(details);
        int i = 100;
        // Report progress to 'UI' thread
        backgroundWorker1.ReportProgress(i);
        // Simulate long task
        System.Threading.Thread.Sleep(0000);            
    }

我想知道哪里出了问题。
