In my project I have to create some temp files in an USB device, which I want to delete on Closing. So I used a code like

this.fcommandHandler = new FileStream(TempFileName,
FileMode.CreateNew, FileAccess.ReadWrite,
FileShare.ReadWrite, 512, FileOptions.DeleteOnClose);

It works fine. But the problem is I want to use one more FileOption, like No buffering.

private const FileOptions FILE_FLAG_NO_BUFFERING = (FileOptions)0x20000000;

this.fcommandHandler = new FileStream(TempFileName,
FileMode.CreateNew, FileAccess.ReadWrite,
FileShare.ReadWrite, 512, FileOptions.DeleteOnClose & FILE_FLAG_NO_BUFFERING);

But its not deleting the File after closing. Please help.
