[DesktopBridge]运行时异常将WPF应用程序转换为“.APPX”后 [英] [DesktopBridge] Runtime Exceptions After convering WPF Application to ".APPX"

问题描述

（这实际上是多部分问题）

Hi,
(This is actually multi-part question)

使用DesktopBridge将小型WPF应用程序转换为.APPX。 现在，当我运行应用程序时，我看到代码抛出的异常在WPF中完美运行。 大多数情况下，这些异常是在读取文件或尝试执行
文件时引起的。

A small WPF application was converted to .APPX using DesktopBridge.  Now when I run the application I see exceptions being thrown from code which works perfectly in WPF.  Mostly these exceptions are caused while reading a file or trying to execute a file.

但是我不知道如何调试自安装的.appx应用程序。 但是我说哪些线路会造成麻烦。

However I don't know how to debug self-installed .appx application.  But I say which lines are causing trouble.

异常＃1。我在下一行收到System.IO.DirectoryNotFoundException。

使用（StreamReader streamReader = new StreamReader（@"Terms \License.txt""，Encoding.UTF8） ））

using (StreamReader streamReader = new StreamReader(@"Terms\License.txt", Encoding.UTF8))

由于WPF应用程序运行良好，因此不太可能，但有人认为安装时可能没有复制License.txt文件。但有没有办法找出.appx App安装在哪个目录中？

Since as WPF application is works perfectly hence its less likely, but one thought was that perhaps file License.txt was not copied while installation. But is there a way to find out in which directory is the .appx App installed itself ?

异常＃2。未知异常：目录名称无效。也许这个例外发生在下一行。

  ProcessStartInfo startInfo = new ProcessStartInfo（PathToJSEXE，jsFilePath + jsFileParameters）;

  ProcessStartInfo startInfo = new ProcessStartInfo(PathToJSEXE, jsFilePath + jsFileParameters);

导致上述两个例外的原因是什么，什么是变通方法？

What is causing above two exceptions, Why and What is workaround ?

任何指针？

问候

推荐答案

您好Richard Freytag，

Hi Richard Freytag,

您需要将这些文件放在其他位置，例如本地应用程序数据存储。

You need to put these files in another location, like the local app data store.

这是因为当你的应用程序被转换时，一些路径将被重定向。例如，应用程序数据被重定向到本地应用程序数据存储。

It’s because when your app is converted, some paths will be redirected. For example, App data is redirected to the local app data store.

建议的模式是在安装包中包含模板文件，然后首先将它们复制到本地应用程序数据文件夹使用。请在此问题中查看Rob的回答：

The recommended pattern is to include the template files in the install package and then copy them to the local app data folder on first use.
