SecureString to Byte[] C#

Question

How would I get a byte[] equivalent of a SecureString (which I get from a PasswordBox)?

My objective is to write these bytes

Answer 1

Per this, http://www.microsoft.com/indonesia/msdn/credmgmt.aspx, you can marshal it into a stock C# string and then convert that into an array of bytes:

static string SecureStringToString( SecureString value )
{
  string s ;
  IntPtr p = Marshal.SecureStringToBSTR( value );
  try
  {
    s = Marshal.PtrToStringBSTR( p ) ;
  }
  finally
  {
    Marshal.FreeBSTR( p ) ;
  }
  return s ;
}

or per this answer, How to convert SecureString to System.String?, you can use Marshal.ReadByte and Marshal.ReadInt16 on the IntPtr to get what you need.
