初始化C#的geckoWebBrowser异常
作者:互联网
我的程序如下引发异常.
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,例外情况如下:
“System .__ ComObject”无法转换接口类型“Gecko.nsIWebNavigation”
以下代码中抛出异常:
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);
}
}
任何帮助将不胜感激.
解决方法:
对于旧版本,您需要将GeckoFX版本与xulrunner的完全正确版本相匹配.
在这里查看您的版本:https://bitbucket.org/geckofx/geckofx/wiki/Version_lists
在这里下载xulrunner:https://releases.mozilla.org/pub/xulrunner/releases/
但是版本45.0大大简化了这一点:
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.
