格式化USB驱动器编程

本文关键字：编程 驱动器 USB 格式化 | 更新日期: 2023-09-27 18:17:32

我正在c#中开发一个应用程序，因此，如果用户确认一个消息框来格式化USB驱动器，从组合框列表中选择，驱动器将被格式化。

我还没有一个想法如何接近这个，然而-我有以下代码:

 public static bool FormatDrive(string driveLetter,
    string fileSystem = "FAT", bool quickFormat = false,
    int clusterSize = 4096, string label = "", bool enableCompression = false)
    {
        if (driveLetter.Length != 2 || driveLetter[1] != ':' || !char.IsLetter(driveLetter[0]))
            return false;
        //query and format given drive         
        ManagementObjectSearcher searcher = new ManagementObjectSearcher
         (@"select * from Win32_Volume WHERE DriveLetter = '" + driveLetter + "'");
        foreach (ManagementObject vi in searcher.Get())
        {
            vi.InvokeMethod("Format", new object[] { fileSystem, quickFormat, clusterSize, label, enableCompression });
        }
        return true;
    }

我不太确定这是如何工作的。这是正确的方式来接近格式化USB驱动器?如果没有，有人能给我指个方向吗?

我试过看Win32_Volume类，但是，再一次，我真的不明白它是如何工作的。这个问题建议使用CreateFile函数。我也看了这个网站。

如果你能给我指点一下方向，我将不胜感激。

格式化USB驱动器编程

也许我还有另一个方法:

    public static bool FormatDrive_CommandLine(char driveLetter, string label = "", string fileSystem = "NTFS", bool quickFormat = true, bool enableCompression = false, int? clusterSize = null)
    {
        #region args check
        if (!Char.IsLetter(driveLetter) ||
            !IsFileSystemValid(fileSystem))
        {
            return false;
        }
        #endregion
        bool success = false;
        string drive = driveLetter + ":";
        try
        {
            var di                     = new DriveInfo(drive);
            var psi                    = new ProcessStartInfo();
            psi.FileName               = "format.com";
            psi.CreateNoWindow         = true; //if you want to hide the window
            psi.WorkingDirectory       = Environment.SystemDirectory;
            psi.Arguments              = "/FS:" + fileSystem +
                                         " /Y" +
                                         " /V:" + label +
                                         (quickFormat ? " /Q" : "") +
                                         ((fileSystem == "NTFS" && enableCompression) ? " /C" : "") +
                                         (clusterSize.HasValue ? " /A:" + clusterSize.Value : "") +
                                         " " + drive;
            psi.UseShellExecute        = false;
            psi.CreateNoWindow         = true;
            psi.RedirectStandardOutput = true;
            psi.RedirectStandardInput  = true;
            var formatProcess          = Process.Start(psi);
            var swStandardInput        = formatProcess.StandardInput;
            swStandardInput.WriteLine();
            formatProcess.WaitForExit();
            success = true;
        }
        catch (Exception) { }
        return success;
    }

首先我自己写代码，现在在http://www.metasharp.net/index.php/Format_a_Hard_Drive_in_Csharp上找到了一个完美的方法

评论中的问题解答:

如果你不想让/q快速格式化

/x参数强制选择卷卸载，如果需要的话。

psi.CreateNoWindow = true;

隐藏终端，使您的应用程序看起来流畅。我的建议是在调试时显示它。

你想调用的是如果驱动器是F:/例如:

FormatDrive_CommandLine('F', "formattedDrive", "FAT32", false, false);

我也尝试过这个，并工作:

public bool FormatUSB(string driveLetter, string fileSystem = "FAT32", bool quickFormat = true,
                                   int clusterSize = 4096, string label = "USB_0000", bool enableCompression = false)
    {
        //add logic to format Usb drive
        //verify conditions for the letter format: driveLetter[0] must be letter. driveLetter[1] must be ":" and all the characters mustn't be more than 2
        if (driveLetter.Length != 2 || driveLetter[1] != ':' || !char.IsLetter(driveLetter[0]))
            return false;
        //query and format given drive 
        //best option is to use ManagementObjectSearcher
        var files = Directory.GetFiles(driveLetter);
        var directories = Directory.GetDirectories(driveLetter);
        foreach (var item in files)
        {
            try
            {
                File.Delete(item);
            }
            catch (UnauthorizedAccessException) { }
            catch (IOException) { }
        }
        foreach (var item in directories)
        {
            try
            {
                Directory.Delete(item);
            }
            catch (UnauthorizedAccessException) { }
            catch (IOException) { }
        }
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"select * from Win32_Volume WHERE DriveLetter = '" + driveLetter + "'");
        foreach (ManagementObject vi in searcher.Get())
        {
            try
            {
                var completed = false;
                var watcher = new ManagementOperationObserver();
                watcher.Completed += (sender, args) =>
                {
                    Console.WriteLine("USB format completed " + args.Status);
                    completed = true;
                };
                watcher.Progress += (sender, args) =>
                {
                    Console.WriteLine("USB format in progress " + args.Current);
                };
                vi.InvokeMethod(watcher, "Format", new object[] { fileSystem, quickFormat, clusterSize, label, enableCompression });
                while (!completed) { System.Threading.Thread.Sleep(1000); }

            }
            catch
            {
            }
        }
        return true;
    }
    #endregion

也许会有帮助。
