C＃DriveInfo的FileInfo [英] C# DriveInfo FileInfo

问题描述

这似乎是一个愚蠢的问题，所以这里有云：

除了解析FileInfo.FullPath串的驱动器号，然后使用DriveInfo（C ）等，以看是否有足够的空间来写该文件。有没有办法摆脱FileInfo的盘符？

解决方案

  FileInfo的F =新FileInfo的（路径）; 
串驱动器= Path.GetPathRoot（f.FullName）; 
  

这将返回C：\。这真的是唯一的办法了。

This may seem like a stupid question, so here goes:

Other than parsing the string of FileInfo.FullPath for the drive letter to then use DriveInfo("c") etc to see if there is enough space to write this file. Is there a way to get the drive letter from FileInfo?

解决方案

FileInfo f = new FileInfo(path);    
string drive = Path.GetPathRoot(f.FullName);

This will return "C:\". That's really the only other way.
