Question

    IWebDriver Driver { get; set; }

    public void InitChrome(IWebDriver e)
    {
        ChromeOptions options = new ChromeOptions();
        options.AddArgument("disable-infobars");
        IWebDriver driver = new ChromeDriver(options);
        Driver =  driver;
    }

    public void Watcher_Changed(object sender, FileSystemEventArgs e)
    {
        InitChrome(Driver);
        string title = Driver.Title;
        Driver.Navigate().GoToUrl("file:///" + filename);
        Driver.Navigate().Refresh();
        InitChrome(Driver);
    }

每次我使用此代码保存文件时，都会启动一个新的Google Chrome实例，如何在保留此行Driver.Navigate().GoToUrl("file:///" + filename);时阻止此操作？

Answer 1

在这种情况下，您只需要WebDriver的一个实例，而单例模式可以帮助您。

public static IWebDriver _driver;

public IWebDriver Driver { 
    get {
        if(_driver == null)
        {  
            var options = new ChromeOptions();
            options.AddArgument("disable-infobars");
            var _driver = new ChromeDriver(options);
        }
        return _driver;
    }
}

public void Watcher_Changed(object sender, FileSystemEventArgs e)
{
    Driver.Navigate().GoToUrl("file:///" + filename);
    Driver.Navigate().Refresh();
}

通过添加

来修复它

    if (Driver == null )
    {
        InitChrome(Driver);
    }

防止浏览器启动超过1次
