当运行安装程序Environment.CurrentDirectory正在产生意想不到的效果 [英] Environment.CurrentDirectory is yielding unexpected results when running installed app

问题描述

背景：

我建立了一个安装程序我的应用程序，和我所有的dll的文件和内容文件都得到正确地复制到 C：\ Program Files文件\ MyCompany的\ MyApp的目录。当我从Visual Studio中运行我的应用程序，一切都很正常。当我运行安装我的应用程序的版本，但是，我得到一个 DirectoryNotFoundException 。这个问题似乎与 Environment.CurrentDirectory 。

我期待 Environment.CurrentDirectory 是...

 C：\\ Program Files文件\\ \\ MyCompany的MyApp的
 

...但它实际上是...

 C：\\的Documents and Settings \\ DanThMan
 

这是怎么回事呢？我该如何解决这个问题？

感谢。

编辑：

好吧，嗯。只有当我运行开始菜单快捷方式发生此问题。如果我MyApp.exe的直接运行，一切都很好。

编辑2：

我想我已经得到了这条底线了。在我的安装程序（这是一个Visual Studio SetupProject），开始菜单快捷方式有一个叫做财产 WorkingFolder ，其中指定快捷方式的目标应用程序将被安装的文件夹。我不小心设置 WorkingFolder 来MyCompany的。它应该是应用程序文件夹。现在，我有它设置正确， Environment.CurrentDirectory 再次按预期工作。感谢您的帮助。

修改3：

不过，看完下面的警告，我已经决定去与以下，以替换 Environment.CurrentDirectory ：

  System.IO.Path.GetDirectoryName（System.Reflection.Assembly.GetEntryAssembly（）位置。）;
 

解决方案

如果你想获得的路径目录下的可执行文件运行时，你不应该依赖于Environment.CurrentDirectory，因为它可以在改变的方式编号（shotrtcut设置等）。请尝试以下选项之一，而不是：

  System.IO.Path.GetDirectoryName（Application.ExecutablePath）;
 

或

  System.IO.Path.GetDirectoryName（System.Reflection.Assembly.GetEntryAssembly（）位置。）;
 

Background:

I built an installer for my app, and all my dll's and content files are getting correctly copied to the C:\Program Files\MyCompany\MyApp directory. When I run my app from Visual Studio, everything works great. When I run the installed version of my app, however, I get a DirectoryNotFoundException. The problem seems to be with Environment.CurrentDirectory.

I was expecting Environment.CurrentDirectory to be...

"C:\\Program Files\\MyCompany\\MyApp"

...but it was actually...

"C:\\Documents and Settings\\DanThMan"

What's going on here? How do I solve this?

Thanks.

EDIT:

Okay, hmm. This problem only occurs if I run the Start Menu shortcut. If I run MyApp.exe directly, everything is fine.

EDIT 2:

I think I've gotten to the bottom of this now. In my Installer (which is a Visual Studio SetupProject), the Start Menu shortcut has a property called WorkingFolder, which "Specifies the folder where the target application for the shortcut will be installed." I had accidentally set WorkingFolder to "MyCompany". It should be "Application Folder". Now that I have it set correctly, Environment.CurrentDirectory is once again working as expected. Thanks for all your help.

EDIT 3:

However, reading the warnings below, I have decided to go with the following as a replacement for Environment.CurrentDirectory:

System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);

解决方案

If you want to get the path to the directory under which your executable runs, you should not rely on the Environment.CurrentDirectory, since it can be changed in a number of ways (shotrtcut settings, etc). Try one of these options instead:

System.IO.Path.GetDirectoryName(Application.ExecutablePath);

or

System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);
