如何使用imdisk和C＃創建RAM磁盤？

Question

我想通過在C＃中的imdisk創建一個RAM目錄。由於cmd命令是這樣的：
imdisk -a -s 512M -m X: -p "/fs:ntfs /q /y"
我查找了如何使用C＃處理cmd命令，並發現了有關ProcessStartInfo（）的幾個提示。這個類的工作方式幾乎和我打算的一樣，但是由於imdisk需要管理員權限，所以我有點被卡住了。即使代碼塊沒有例外地執行，我也沒有在Windows資源管理器中看到任何新設備。

 try 
     { 
      string initializeDisk = "imdisk -a "; 
      string imdiskSize  = "-s 1024M "; 
      string mountPoint  = "-m "+ MountPoint + " "; 
      string formatHdd  = "-p '/fs:ntfs /q /y' "; 

      SecureString password = new SecureString(); 
      password.AppendChar('0'); 
      password.AppendChar('8'); 
      password.AppendChar('1'); 
      password.AppendChar('5'); 
      ProcessStartInfo procStartInfo = new ProcessStartInfo(); 
      procStartInfo.UseShellExecute = false; 
      procStartInfo.CreateNoWindow = true; 
      procStartInfo.RedirectStandardError = true; 
      procStartInfo.FileName   = "cmd"; 
      procStartInfo.Verb    = "runas"; 
      procStartInfo.UserName   = "Admin"; 
      procStartInfo.Password   = password; 
      procStartInfo.Arguments   = initializeDisk + imdiskSize + mountPoint + formatHdd; 
      Process.Start(procStartInfo); 

     catch (Exception objException) 
     { 
      Console.WriteLine(objException); 
     } 

我希望有人能給我一點提示，現在我沒有想法。

Answer 1

不CMD.EXE必須經過的/ C命令行選項來運行命令穿過作爲參數？可能是因爲你沒有在參數的前面添加「/ C」，cmd.exe只是忽略了你在procStartInfo.Arguments中傳遞的內容。

Answer 2

那麼我以不同的方式解決了我的問題。不知何故，似乎imdisk沒有按照它應該的方式格式化新的RamDisk，因此沒有創建磁盤。一旦我刪除格式化選項，磁盤就會被創建並需要格式化。因此，我開始另一個進程，並使用cmd命令「格式驅動器：」

對於任何人誰是有興趣的，我的解決方案如下：

class RamDisk 
{ 
    public const string MountPoint = "X:"; 

    public void createRamDisk() 
    { 

     try 
     { 
      string initializeDisk = "imdisk -a "; 
      string imdiskSize  = "-s 1024M "; 
      string mountPoint  = "-m "+ MountPoint + " "; 


      ProcessStartInfo procStartInfo = new ProcessStartInfo(); 
      procStartInfo.UseShellExecute = false; 
      procStartInfo.CreateNoWindow = true; 
      procStartInfo.FileName   = "cmd"; 
      procStartInfo.Arguments   = "/C " + initializeDisk + imdiskSize + mountPoint; 
      Process.Start(procStartInfo); 

      formatRAMDisk(); 

     } 
     catch (Exception objException) 
     { 
      Console.WriteLine("There was an Error, while trying to create a ramdisk! Do you have imdisk installed?"); 
      Console.WriteLine(objException); 
     } 

    } 

    /** 
    * since the format option with imdisk doesn't seem to work 
    * use the fomat X: command via cmd 
    * 
    * as I would say in german: 
    * "Von hinten durch die Brust ins Auge" 
    * **/ 
    private void formatRAMDisk(){ 

     string cmdFormatHDD = "format " + MountPoint + "/Q /FS:NTFS"; 

     SecureString password = new SecureString(); 
     password.AppendChar('0'); 
     password.AppendChar('8'); 
     password.AppendChar('1'); 
     password.AppendChar('5'); 

     ProcessStartInfo formatRAMDiskProcess = new ProcessStartInfo(); 
     formatRAMDiskProcess.UseShellExecute = false; 
     formatRAMDiskProcess.CreateNoWindow  = true; 
     formatRAMDiskProcess.RedirectStandardInput  = true; 
     formatRAMDiskProcess.FileName   = "cmd"; 
     formatRAMDiskProcess.Verb    = "runas"; 
     formatRAMDiskProcess.UserName   = "Administrator"; 
     formatRAMDiskProcess.Password   = password; 
     formatRAMDiskProcess.Arguments   = "/C " + cmdFormatHDD; 
     Process process       = Process.Start(formatRAMDiskProcess); 

     sendCMDInput(process); 
    } 

    private void sendCMDInput(Process process) 
    { 
     StreamWriter inputWriter = process.StandardInput; 
     inputWriter.WriteLine("J"); 
     inputWriter.Flush(); 
     inputWriter.WriteLine("RAMDisk for valueable data"); 
     inputWriter.Flush(); 
    } 

    public string getMountPoint() 
    { 
     return MountPoint; 
    } 
}
