C#判断指定分区是否是ntfs格式的方法

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;
  }
 }
}
