23. February 2013 Hossein ASP.NET (0)

There are multiple GUID forms that can be generated in asp.net. Here are some examples: 

  • Guid.NewGuid().ToString() => 36 characters (Hyphenated)
    outputs: 12345678-1234-1234-1234-123456789abc

  • Guid.NewGuid().ToString("D") => 36 characters (Hyphenated, same as ToString())
    outputs: 12345678-1234-1234-1234-123456789abc

  • Guid.NewGuid().ToString("N") => 32 characters (Digits only)
    outputs: 12345678123412341234123456789abc

  • Guid.NewGuid().ToString("B") => 38 characters (Braces)
    outputs: {12345678-1234-1234-1234-123456789abc}

  • Guid.NewGuid().ToString("P") => 38 characters (Parentheses)
    outputs: (12345678-1234-1234-1234-123456789abc)
