C enumeration type and structure type instance resolution

This paper takes C# as an example to explain the usage of enumeration type and structure type. The program mainly demonstrates the usage of enumeration type and structure type through personal phone book. The specific code is as follows:

using System;
class ID
{
 // Define enumerated types 
 public enum Sex
 {
 male, female
 };// Make sure you don't forget the semicolon here 
 // Defines the structure type of the phone book 
 public struct TelBook
 {
 public string name;
 public Sex sex;// The gender type is an enumerated type 
 public string number;
 }
 // every 1 Lines of print 1 Bit user's phone book information 
 public static void TelPrint( TelBook Someone )
 {
 Console.Write( Someone.name + "\t");
 Console.Write( Someone.sex + "\t");
 Console.Write( Someone.number + "\r\n");
 }
 public static void Main()
 {
 TelBook Joey, Rose;// The statement TelBook Structure type two user Joey and Rose
 Joey.name= "Joey"; // Initialize the Joey Phone book information 
 Joey.sex= Sex.male;
 Joey.number = "84113128";
 Rose.name = "Rose";// Initialize the Rose Phone book information 
 Rose.sex = Sex.female;
 Rose.number = "84117456";
 TelPrint ( Joey ); // Print the phone book for two users 
 TelPrint ( Rose );
 }
}
