重置加载栏

我目前正在做一个Web浏览器的辅助项目，我似乎陷入了困境。

我在网络浏览器的左下角有一个加载栏，它功能齐全，只是它没有重置绿色加载栏（它在导航时用绿色填充栏，但之后不会重置）。

万一我遇到一些奇怪的情况，它会因为某种原因而出现错误，我最近遇到了一些奇怪的错误，我正试图将它们排除在外。

我正在寻找我可以尝试的建议和窍门。

这是源代码：

namespace WeWolf_Browser
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
        }
        //This Function Will Terminate The Software From The MenuStrip (File > Exit)
        private void exitToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.Close();
        }
        //This Function Will Make a Message Box Pop Up On The Users Screen With Information About The Software.
        private void aboutToolStripMenuItem_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Simple Browser Created By Me");
        }

        //This Will Navigate the browser to the users input.
        private void button1_Click(object sender, EventArgs e)
        {
            NavigateToPage();
        }

        //This is the "Core "Function" "  That Will Navigate The URL With The Enter KeyChar
        private void NavigateToPage()
        {
            toolStripStatusLabel1.Text = "Navigation Loading";
            webBrowser1.Navigate(textBox1.Text);
        }
        //This Action will allow people use use the KeyPress Enter to navigate to the desired URL.
        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)ConsoleKey.Enter)
               {
                NavigateToPage();
            }
        }

        //This WIll Make The Progress Bar Load While The Browser Is Loading.
        private void webBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
        {
            if (e.CurrentProgress > 0 && e.MaximumProgress > 0)
            {
                toolStripProgressBar1.ProgressBar.Value = (int)(e.CurrentProgress * 100 / e.MaximumProgress);
            }
        }
        private void toolStripStatusLabel1_Click(object sender, EventArgs e)
        {
        }
        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            toolStripStatusLabel1.Text = "Navigation Has Finished";
        }
    }
}

try
{
    // your actual code
}
catch (Exception ex)
{
    // show it to the user
    MessageBox.Show(ex.Message);
    // reset progress bar
    toolStripProgressBar1.ProgressBar.Value = 0;
}
