如何获取相对路径中的文件在C# [英] How to get files in a relative path in C#
问题描述
如果我有一个名为app.exe的可执行文件,这是我在C#中编码的,那么如何使用相对路径从与app.exe相同目录中的文件夹中获取文件?
If I have an executable called app.exe which is what I am coding in C#, how would I get files from a folder loaded in the same directory as the app.exe, using relative paths?
这会在路径异常中引发非法字符:
This throws an illegal characters in path exception:
string [ ] files = Directory.GetFiles ( "\\Archive\\*.zip" );
如何在C#中执行此操作?
How would one do this in C#?
推荐答案
要确保您具有应用程序的路径(而不仅仅是当前目录),请使用:
To make sure you have the application's path (and not just the current directory), use this:
http://msdn.microsoft.com /en-us/library/system.diagnostics.process.getcurrentprocess.aspx
现在你有一个 Process
表示正在运行的进程的对象。
Now you have a Process
object that represents the process that is running.
然后使用 Process.MainModule.FileName
:
Then use Process.MainModule.FileName
:
http://msdn.microsoft.com/en-us/library/system.diagnostics.processmodule.filename.aspx
最后,使用 Path.GetDirectoryName
获取文件夹c维护.exe:
Finally, use Path.GetDirectoryName
to get the folder containing the .exe:
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx
所以这就是你想要的:
string folder = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + @"\Archive\";
string filter = "*.zip";
string[] files = Directory.GetFiles(folder, filter);
(注意\Archive\
从你的问题现在是 @\Archive\
:你需要@,以便 \
反斜杠不会被解释为转义序列的开始)
(Notice that "\Archive\"
from your question is now @"\Archive\"
: you need the @ so that the \
backslashes aren't interpreted as the start of an escape sequence)
