獲取邏輯驅動器

Question

我用下面的代碼獲取邏輯驅動器：

string[] strDrives = Environment.GetLogicalDrives(); 

但是當我想通過它來迭代，發生異常時，與消息：

Drive Not Ready 

我怎樣才能準備就緒驅動器？

Answer 1

使用DriveInfo確定驅動器是否準備就緒。

foreach (var oneDrive in strDrives) 
{ 
    var drive = new DriveInfo(oneDrive) 
    if (drive.IsReady) 
    { 
     // Do something with the drive... 
    } 
} 

Answer 2

這也可以，當然可以使用LINQ實現：

IEnumerable<DriveInfo> readyDrives = Environment.GetLogicalDrives() 
    .Select(s => new DriveInfo(s)) 
    .Where(di => di.IsReady); 

Answer 3

我傾向於做：

List<DriveInfo> driveInfo = new List<DriveInfo>(from drive in DriveInfo.GetDrives() where drive.IsReady select drive);
