Test code:

Using system;using system.collections.generic;using system.linq;using system.text;namespace GuidToString{  class Program  {    static void Main (string[] args)    {      Console.WriteLine ("--" + System.Guid.NewGuid (). ToString ());      Console.WriteLine ("N-->" + System.Guid.NewGuid (). ToString ("N"));      Console.WriteLine ("D-->" + System.Guid.NewGuid (). ToString ("D"));      Console.WriteLine ("B-->" + System.Guid.NewGuid (). ToString ("B"));      Console.WriteLine ("P-->" + System.Guid.NewGuid (). ToString ("P"));      Console.WriteLine ("X-->" + System.Guid.NewGuid (). ToString ("X"));      Console.readkey ();}}}  

Test results:

Note: You can use only N, D, B, P, X (case-insensitive) NULL, and other letters will cause an exception

The format string can only be "D", "D", "N", "n", "P", "P", "B", "B", "X", or "X".

Exception Condition:

The following are normal:

Using system;using system.collections.generic;using system.linq;using system.text;namespace GuidToString{class program {static void Main (string[] args) {Console.WriteLine ("--" + System.Guid.NewGuid ().      ToString ()); Console.WriteLine ("--" + System.Guid.NewGuid ().      ToString ("")); Console.WriteLine ("N-->" + System.Guid.NewGuid ().      ToString ("N")); Console.WriteLine ("N-->" + System.Guid.NewGuid ().      ToString ("n")); Console.WriteLine ("D-->" + System.Guid.NewGuid ().      ToString ("D")); Console.WriteLine ("D-->" + System.Guid.NewGuid ().      ToString ("D")); Console.WriteLine ("B-->" + System.Guid.NewGuid ().      ToString ("B")); Console.WriteLine ("B-->" + System.Guid.NewGuid ().      ToString ("B")); Console.WriteLine ("P-->" + System.Guid.NewGuid ().      ToString ("P")); Console.WriteLine ("P-->" + System.Guid.NewGuid ().      ToString ("P")); Console.WriteLine ("X-->" + System.Guid.NewGuid ().      ToString ("X")); Console.WriteLine ("X-->" + SyStem. Guid.NewGuid ().      ToString ("x"));    Console.readkey (); }  }}
