Get the drive letter from a path string or FileInfo
提问by maxfridbe
This may seem like a stupid question, so here goes:
这似乎是一个愚蠢的问题，所以这里是：
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?
除了解析驱动器号的 FileInfo.FullPath 字符串然后使用 DriveInfo("c") 等查看是否有足够的空间来写入此文件。有没有办法从 FileInfo 获取驱动器号？

FileInfo f = new FileInfo(path);
string drive = Path.GetPathRoot(f.FullName);
This will return "C:\". That's really the only other way.
这将返回“C:\”。这真的是唯一的其他方式。

Nothing wrong with a little string parsing :-)
一点字符串解析没有错:-)
FullPath.Substring(0,1);

Well, there's also this:
嗯，还有这个：
FileInfo file = new FileInfo(path);
DriveInfo drive = new DriveInfo(file.Directory.Root.FullName);
And hey, why not an extension method?
嘿，为什么不是扩展方法？
public static DriveInfo GetDriveInfo(this FileInfo file)
{
return new DriveInfo(file.Directory.Root.FullName);
}
Then you could just do:
那么你可以这样做：
DriveInfo drive = new FileInfo(path).GetDriveInfo();

You can get all drive in system using this code :
您可以使用以下代码获取系统中的所有驱动器：
foreach (DriveInfo objDrive in DriveInfo.GetDrives())
{
Response.Write("</br>Drive Type : " + objDrive.Name);
Response.Write("</br>Drive Type : " + objDrive.DriveType.ToString());
Response.Write("</br>Available Free Space : " + objDrive.AvailableFreeSpace.ToString() + "(bytes)");
Response.Write("</br>Drive Format : " + objDrive.DriveFormat);
Response.Write("</br>Total Free Space : " + objDrive.TotalFreeSpace.ToString() + "(bytes)");
Response.Write("</br>Total Size : " + objDrive.TotalSize.ToString() + "(bytes)");
Response.Write("</br>Volume Label : " + objDrive.VolumeLabel);
Response.Write("</br></br>");
}
