为什么System.AppDomain.CurrentDomain.BaseDirectory返回不同的结果? [英] Why does System.AppDomain.CurrentDomain.BaseDirectory return different results?

问题描述

我将数据库的路径(带有一些xml文件的文件夹)存储在app.config中.在启动时，我检查路径是否存在.如果不存在，我想将路径设置为默认路径.代码如下:

I store the path of my database (a folder with some xml files) in the app.config. At the startup I check, if the path exists. If it doesn't exist, I want to set the path to the default path. Code looks like this:

public void CheckAndRepairSettings()
{
        /* Check Paths */
        if(GetDatabasePath() == null)
             SetDatabasePath(System.AppDomain.CurrentDomain.BaseDirectory + "DataBase");
}

GetDatabasePath()从app.config读取路径，而SetDatabasePath()将路径写入app.config.这些方法工作正常.

GetDatabasePath() reads the path form the app.config and SetDatabasePath() writes the path to the app.config. These Methods are working fine.

我的问题是System.AppDomain.CurrentDomain.BaseDirectory.如果我在应用程序调试模式下运行此命令，则会得到: "F:\ Office \ Projekte_Software \ ServiceTool \ _Work \ ServiceSoftware \ ServiceSoftware \ bin \ Debug \"

My promblem is the System.AppDomain.CurrentDomain.BaseDirectory. If I run this in my applications debug mode I get: "F:\Office\Projekte_Software\ServiceTool\_Work\ServiceSoftware\ServiceSoftware\bin\Debug\"

我还使用NUnit进行某些单元测试.如果我以调试模式运行NUnit，则会得到: "F:\ Office \ Projekte_Software \ ServiceTool \ _Work \ ServiceSoftware \ ServiceSoftware.UnitTests \ bin \ Debug"

I additionally use NUnit for some unit tests. If I run NUnit in debug mode I get : "F:\Office\Projekte_Software\ServiceTool\_Work\ServiceSoftware\ServiceSoftware.UnitTests\bin\Debug"

在NUnit调试模式下，路径中没有结尾的反斜杠"\"，因此在连接CheckAndRepairSettings()中的路径字符串时，我得到的路径不存在.

There is no trailing Backslash "\" in the path in NUnit debug mode, so I get a non existing path when I concatenate the path-string in my CheckAndRepairSettings().

为什么这种行为如此不同?

Why does this behave so different?

推荐答案

您应该使用Path.Combine来连接路径，它可以处理与现有/不存在的路径分隔符有关的问题

You should use Path.Combine to concatenate paths, it handles issues regarding existing/non-existing (among other things) path separators

为什么其中一个包含斜杠而另一个不包含斜杠，可能与nUnit如何创建在其下运行测试的appdomain有关

Why one includes ending slash the other one doesn't is probably related to how nUnit creates the appdomain under which it runs its tests
