检查目录是否就绪System.IO.Directory

Question

有没有办法检查一个驱动程序是否准备好了？

因为我列出了所有的目录，例如，当它到达dvd时，我得到一个异常，说驱动程序还没有准备好。

非常感谢

@{
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;
}
}

非常感谢

看一看DriveInfo.IsReady属性。

  DriveInfo[] allDrives = DriveInfo.GetDrives();

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