What is the string length of a GUID?

by

It depends on how you format the Guid:

  • 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)

  • Guid.NewGuid().ToString("X") = 68 characters (Hexadecimal)
    outputs: {0x12345678,0x1234,0x1234,{0x12,0x34,0x12,0x34,0x56,0x78,0x9a,0xbc}}
