本文实例讲述了C#判断指定驱动器是否是Fat分区格式的方法。分享给大家供大家参考。具体如下：

using System; using System.IO; namespace RobvanderWoude { class IsFAT { public static int Main( string[] args ) { try { if ( args.Length == 0 ) { return WriteError( string.Empty ); } if ( args.Length > 1 ) { return WriteError( "Invalid number of arguments." ); } string drive = args[0].ToUpper( ); DriveInfo[] allDrives = DriveInfo.GetDrives( ); foreach ( DriveInfo drv in allDrives ) { if ( drive == drv.Name.Substring( 0, 2 ) ) { if ( drv.IsReady ) { Console.WriteLine( drv.DriveFormat.ToUpper( ) ); if (drv.DriveFormat == "FAT" || drv.DriveFormat == "FAT32") { return 0; } else { return 2; } } else { Console.WriteLine(drv.DriveType.ToString().ToUpper()); return 1; } } } return WriteError( "Invalid drive specification." ); } catch ( Exception e ) { // Display help text with error message return WriteError( e ); } } // Code to display help and optional error message, //by Bas van der Woude public static int WriteError( Exception e ) { return WriteError( e == null ? null : e.Message ); } public static int WriteError( string errorMessage ) { string fullpath = Environment.GetCommandLineArgs().GetValue(0).ToString(); string[] program = fullpath.Split( '' ); string exeName = program[program.GetUpperBound(0)]; exeName = exeName.Substring(0, exeName.IndexOf('.')); if ( string.IsNullOrEmpty( errorMessage ) == false ) { Console.Error.WriteLine(); Console.ForegroundColor = ConsoleColor.Red; Console.Error.Write( "ERROR: " ); Console.ForegroundColor = ConsoleColor.White; Console.Error.WriteLine( errorMessage ); Console.ResetColor(); } Console.Error.WriteLine(); Console.Error.WriteLine("IsFAT, Version 1.00"); Console.Error.WriteLine("Return 'errorlevel' 0 if the specified drive is FAT or FAT32 formated"); Console.Error.WriteLine(); Console.Error.Write("Usage: "); Console.ForegroundColor = ConsoleColor.White; Console.Error.WriteLine("{0} drive:", exeName.ToUpper()); Console.ResetColor( ); Console.Error.WriteLine(); Console.Error.WriteLine("Note: Returns 0 if FAT or FAT32, 2 if not, 1 if not ready or invalid."); Console.Error.WriteLine(); Console.Error.WriteLine("Written by Rob van der Woude"); return 1; } } }

希望本文所述对大家的C#程序设计有所帮助。
