c# - 为 C# 初始化 geckoWebBrowser 异常

Question

我下面的程序抛出异常。

Program.cs如下:

    static void Main()
    {
        Gecko.Xpcom.Initialize("D:\\xulrunner\\");
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());

    }

Form1.cs如下:

    private void Form1_Load(object sender, EventArgs e)
    {
        //Gecko.Xpcom.Initialize("D:\\xulrunner\\");

        geckoWebBrowser1.Navigate("http://www.google.com");

    }

翻译自中文，异常如下:

“System.__ComObject”无法转换接口(interface)类型“Gecko.nsIWebNavigation”

异常在以下代码中抛出:

public ChromeContext()
{
    using (var appShallSvc = Xpcom.GetService2<nsIAppShellService>(Contracts.AppShellService))
    {
        webNav = appShallSvc.Instance.CreateWindowlessBrowser(true).AsComPtr(); //this is where the exception is thrown

        webNav.Instance.LoadURI("chrome://global/content/alerts/alert.xul", 0, null, null, null);

    }

}

我们将不胜感激。

对于旧版本，您需要将 GeckoFX 版本与 xulrunner 的正确版本相匹配。

在此处检查您的版本:https://bitbucket.org/geckofx/geckofx/wiki/Version_lists

在这里下载 xulrunner:https://releases.mozilla.org/pub/xulrunner/releases/

但这在 45.0 版中已大大简化:

For Geckofx 45.0 and newer publishing has been moved to a nuget package model, which includes the both the geckofx files and the required firefox files.
