檢查目錄是否準備就緒System.IO.Directory

Question

有沒有辦法檢查驅動程序是否準備就緒？

由於我列出所有目錄，例如，當它到達DVD時，我收到一個異常說明驅動程序沒有準備好。

Thanls很多

@{ 
try 
{ 
    //Resgata todos os drivers Lógicos do Sistema 
    string[] drives = System.IO.Directory.GetLogicalDrives(); 

    Response.Write("<ul class=\"jqueryFileTree\" style=\"display: none;\">\n"); 

    //Itera sobre cada driver no array 
    foreach(string drive in directoryEntries) { 


     //Para cada driver cria um LI A 
     Response.Write("\t<li class=\"directory collapsed\"><a href=\"#\" rel=\"" + drive + "\">" + drive + "</a></li>\n"); 

     //Resgata subDiretórios de cada driver 
     string[] directoryEntries = System.IO.Directory.GetFileSystemEntries(drive); 
    } 


} 
catch (Exception) 
{ 

    throw; 
} 
} 

非常感謝

看一看的DriveInfo.IsReady財產。

DriveInfo[] allDrives = DriveInfo.GetDrives(); 

    foreach (DriveInfo d in allDrives) 
    { 
     if (d.IsReady == true) 
     { 
     // do something 
     } 
    }
