本文实例讲述了C#判断指定分区是否是ntfs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 IsNTFS { 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 == "NTFS" ) { 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( "IsNTFS, Version 1.00" ); Console.Error.WriteLine( "Return 'errorlevel' 0 if the specified drive is NTFS 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 NTFS, 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。
