如何調用一個方法，需要在C＃中的多個參數

Question

我是新的C＃和我有這個小程序中的問題 我想返回方法ClientsDetails中輸入的信息在方法Print（）中使用它們。 任何幫助PLZ？

public static void Main(string[] args) 
    { 

     ClientsDetails(); 

     Print(???,???,???); 

     Console.ReadLine(); 


    } 

    public static void ClientsDetails() 
    { 
     Console.Write("Client's first name: "); 
     string firstName = Console.ReadLine(); 
     Console.Write("Client's last name: "); 
     string lastName = Console.ReadLine(); 
     Console.Write("Client's birthdate: "); 
     string birthday = Console.ReadLine(); 
    } 

    public static void Print(string first, string last, string birthday) 
    { 
     Console.WriteLine("Client : {0} {1} was born on: {2}", first, last, Birthday); 
    } 
} 

Answer 1

還有就是，你可以通過所需參數的方法方式堆，因此，例如簡單的，你可以做這樣的：

String f = "first string"; 
String l = "last string"; 
String b = "birthday string"; 
Print(f,l,b); 

BTW，你的情況看來，你希望用戶的輸入被傳遞給Print方法，所以一個簡單的方法是隻需調用Print方法您ClientsDetails法裏是這樣的：

Print(firstName, lastName, birthday); 

有關這方面的綜合資源，您可以一如既往地參考docs。目前你可以忽略Async Methods部分。

我剛剛根據您的要求更正了您的程序。

你可以使用一個結構：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

namespace ConsoleApplication1 
{ 
    struct Person{ 
     public static FirstName; 
     public static LastName; 
     public static Birthday; 
    } 
    class Program 
    { 
     static void Main(string[] args) 
     {     
      Person person = ClientsDetails(); 
      Print(person.FirstName, person.LastName, person.Birthday); 
      Console.ReadKey(); 
     } 

     public static Person ClientsDetails() 
     { 
      Person returnValue = new Person(); 
      Console.Write("Client's first name: "); 
      returnValue.FirstName = Console.ReadLine(); 
      Console.Write("Client's last name: "); 
      returnValue.LastName = Console.ReadLine(); 
      Console.Write("Client's birthdate: "); 
      returnValue.Birthday = Console.ReadLine(); 
      return returnValue; 
     } 

     public static void Print(string first, string last, string birthday) 
     { 
      Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday)); 
     } 
    } 
} 

或數組：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     {     
      string person = ClientsDetails(); 
      Print(person[0], person[1], person[2]); 
      Console.ReadKey(); 
     } 

     public static string[] ClientsDetails() 
     { 
      string[] returnValue = new string[3]; 
      Console.Write("Client's first name: "); 
      returnValue[0] = Console.ReadLine(); 
      Console.Write("Client's last name: "); 
      returnValue[1] = Console.ReadLine(); 
      Console.Write("Client's birthdate: "); 
      returnValue[3] = Console.ReadLine(); 
      return returnValue; 
     } 

     public static void Print(string first, string last, string birthday) 
     { 
      Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday)); 
     } 
    } 
} 

或引用（按引用傳遞）：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

namespace ConsoleApplication1 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     {  
      string firstName, lastName, birthday; 
      ClientsDetails(ref firstName, ref lastName, ref birthday); 
      Print(firstName, lastName, birthday); 
      Console.ReadKey(); 
     } 

     public static void ClientsDetails(ref string firstName, ref string lastName, ref string birthday) 
     { 
      Console.Write("Client's first name: "); 
      firstName = Console.ReadLine(); 
      Console.Write("Client's last name: "); 
      lastName = Console.ReadLine(); 
      Console.Write("Client's birthdate: "); 
      birthday = Console.ReadLine(); 
     } 

     public static void Print(string first, string last, string birthday) 
     { 
      Console.WriteLine(String.Format("Client : {0} {1} was born on: {2}", first, last, birthday)); 
     } 
    } 
}
