Get disk Capacity Method c#/c++

• C # methods

  string drivename ="C:\ \";

  System. IO. DriveInfo[] drivers = System. IO. DriveInfo. Getdrives();

  foreach (var drive in drivers)

  {

  if (drivename = = Drive. Name)

  Console. WriteLine(drive. Totalfreespace /(1024x768 * 1024x768 *1.0F) + "G");

  }

  C # can only fetch all of the disks at once, so if you specify a disk, you need to judge and get the Space unit in bytes (byte)

• C + + Methods

  DWORD64 qwfreebytes, qwfreebytestocaller, qwtotalbytes;

  Bresult =GetDiskFreeSpaceEx(TEXT("C:"),

  (pularge_integer) &Qwfreebytestocaller,

  (pularge_integer) &qwtotalbytes,

  (pularge_integer) &qwfreebytes);

  If (bresult)

  {

  cout <<"Use GetDiskFreeSpaceEx"<< Endl;

  cout <<"total Byte:"<< qwtotalbytes << Endl;

  cout <<"freebyte:"<< qwfreebytes << Endl;

  cout <<"Freebyte available:"<< qwfreebytestocaller << Endl ;

  cout <<"Free G"<< qwfreebytestocaller /1024x768/ 1024x768 / 1024x768 * 1.0F << Endl;

  }

  The GetDiskFreeSpaceEx function is explained on MSDN

  BOOL WINAPI GetDiskFreeSpaceEx (
  _in_opt_ LPCTSTR Lpdirectoryname,
  _out_opt_ Pularge_integer lpfreebytesavailable,
  _out_opt_ Pularge_integer Lptotalnumberofbytes,
  _out_opt_ Pularge_integer Lptotalnumberoffreebytes
  );

  GetDiskFreeSpaceEx gets the same data unit as Byte
