如何傳遞一個id號字符串到這個類

Question

我是一個vb人，但不得不在c＃中使用這個id號碼類。我是從http://www.codingsanity.com/idnumber.htm：

namespace Utilities 
{ 
    [Serializable] 
    public class IdentityNumber 
    { 
     public enum PersonGender 
     { 
      Female = 0, 
      Male = 5 
     } 

     public enum PersonCitizenship 
     { 
      SouthAfrican = 0, 
      Foreign = 1 
     } 

     static Regex _expression; 
     Match _match; 
     const string _IDExpression = @"(?<Year>[0-9][0-9])(?<Month>([0][1-9])|([1][0-2]))(?<Day>([0-2][0-9])|([3][0-1]))(?<Gender>[0-9])(?<Series>[0-9]{3})(?<Citizenship>[0-9])(?<Uniform>[0-9])(?<Control>[0-9])"; 

     static IdentityNumber() 
     { 
      _expression = new Regex(_IDExpression, RegexOptions.Compiled | RegexOptions.Singleline); 
     } 

     public IdentityNumber(string IDNumber) 
     { 
      _match = _expression.Match(IDNumber.Trim()); 
     } 

     public DateTime DateOfBirth 
     { 
      get 
      { 
       if(IsUsable == false) 
       { 
        throw new ArgumentException("ID Number is unusable!", "IDNumber"); 
       } 
       int year = int.Parse(_match.Groups["Year"].Value); 

       // NOTE: Do not optimize by moving these to static, otherwise the calculation may be incorrect 
       // over year changes, especially century changes. 
       int currentCentury = int.Parse(DateTime.Now.Year.ToString().Substring(0, 2) + "00"); 
       int lastCentury = currentCentury - 100; 
       int currentYear = int.Parse(DateTime.Now.Year.ToString().Substring(2, 2)); 

       // If the year is after or at the current YY, then add last century to it, otherwise add 
       // this century. 
       // TODO: YY -> YYYY logic needs thinking about 
       if(year > currentYear) 
       { 
        year += lastCentury; 
       } 
       else 
       { 
        year += currentCentury; 
       } 
       return new DateTime(year, int.Parse(_match.Groups["Month"].Value), int.Parse(_match.Groups["Day"].Value)); 
      } 
     } 

     public PersonGender Gender 
     { 
      get 
      { 
       if(IsUsable == false) 
       { 
        throw new ArgumentException("ID Number is unusable!", "IDNumber"); 
       } 
       int gender = int.Parse(_match.Groups["Gender"].Value); 
       if(gender < (int) PersonGender.Male) 
       { 
        return PersonGender.Female; 
       } 
       else 
       { 
        return PersonGender.Male; 
       } 
      } 
     } 

     public PersonCitizenship Citizenship 
     { 
      get 
      { 
       if(IsUsable == false) 
       { 
        throw new ArgumentException("ID Number is unusable!", "IDNumber"); 
       } 
       return (PersonCitizenship) Enum.Parse(typeof(PersonCitizenship), _match.Groups["Citizenship"].Value); 
      } 
     } 

     /// <summary> 
     /// Indicates if the IDNumber is usable or not. 
     /// </summary> 
     public bool IsUsable 
     { 
      get 
      { 
       return _match.Success; 
      } 
     } 

     /// <summary> 
     /// Indicates if the IDNumber is valid or not. 
     /// </summary> 
     public bool IsValid 
     { 
      get 
      { 
       if(IsUsable == true) 
       { 
        // Calculate total A by adding the figures in the odd positions i.e. the first, third, fifth, 
        // seventh, ninth and eleventh digits. 
        int a = int.Parse(_match.Value.Substring(0, 1)) + int.Parse(_match.Value.Substring(2, 1)) + int.Parse(_match.Value.Substring(4, 1)) + int.Parse(_match.Value.Substring(6, 1)) + int.Parse(_match.Value.Substring(8, 1)) + int.Parse(_match.Value.Substring(10, 1)); 

        // Calculate total B by taking the even figures of the number as a whole number, and then 
        // multiplying that number by 2, and then add the individual figures together. 
        int b = int.Parse(_match.Value.Substring(1, 1) + _match.Value.Substring(3, 1) + _match.Value.Substring(5, 1) + _match.Value.Substring(7, 1) + _match.Value.Substring(9, 1) + _match.Value.Substring(11, 1)); 
        b *= 2; 
        string bString = b.ToString(); 
        b = 0; 
        for(int index = 0; index < bString.Length; index++) 
        { 
         b += int.Parse(bString.Substring(index, 1)); 
        } 

        // Calculate total C by adding total A to total B. 
        int c = a + b; 

        // The control-figure can now be determined by subtracting the ones in figure C from 10. 
        string cString = c.ToString() ; 
        cString = cString.Substring(cString.Length - 1, 1) ; 
        int control = 0; 

        // Where the total C is a multiple of 10, the control figure will be 0. 
        if(cString != "0") 
        { 
         control = 10 - int.Parse(cString.Substring(cString.Length - 1, 1)); 
        } 

        if(_match.Groups["Control"].Value == control.ToString()) 
        { 
         return true; 
        } 
       } 

       return false; 
      } 
     } 
    } 
} 

能有人告訴了我的語法如何通過一個ID號到類？

Answer 1

您必須使用構造函數。

var someNumber = new IdentityNumber("123456"); 

然後，您可以使用該類的屬性來找出該Id編號的具體內容。

Console.WriteLine (someNumber.DateOfBirth); 
Console.WriteLine (someNumber.Gender); 
Console.WriteLine (someNumber.Citizenship); 
Console.WriteLine (someNumber.IsValid); 
Console.WriteLine (someNumber.IsUsable); 

Answer 2

IdentityNumber number = new IdentityNumber("123456"); 

Answer 3

所有你需要的是使用提供的構造像

IdentityNumber someNumber = new IdentityNumber("006834");
