ClickOnce相关

Question

在使用ClickOnce将WPF应用程序发布到中心位置之后，当用户尝试访问应用程序时，我将得到以下异常。还有其他的应用程序，它们可以正常工作，只有当它们访问特定的应用程序时才会发出问题。

我无法解决这一问题的原因，因此例外情况似乎没有多大帮助。

Answer 1

现在已经修好了。以下是解决上述问题的办法。

应用程序在下载和启动之前就崩溃了。为了说明问题，我附上了DispatcherUnhandedException处理程序，以了解更多有关它的信息。有了下面的步骤，我就能够从日志文件中找到确切的异常。在我的例子中，这与虚拟机配置文件权限有关。你的情况可能完全不同。然而，这种方法将帮助您过滤根本原因。

<Application x:Class="xxxxxxxx.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml" DispatcherUnhandledException="ApplicationDispatcherUnhandledException">

和

void ApplicationDispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
        {

            var theException = e.Exception;
            var theErrorPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) +"\\IntraDataCopyError.txt";
            using (System.IO.TextWriter theWriter = new System.IO.StreamWriter(theErrorPath, true))
            {
                var theNow = DateTime.Now;
                theWriter.WriteLine("Error log at : " + theNow.ToShortDateString() + " " + theNow.ToShortTimeString());
                while (theException != null)
                {
                    theWriter.WriteLine("Exception: " + theException);
                    theException = theException.InnerException;
                }
            }
            MessageBox.Show("The program aborted due to following issue.\n" + theErrorPath);
            e.Handled = true;
            Application.Current.Shutdown();

        }
