C＃從字符串

Question

鑄造詮釋我想明白，我怎麼能有這麼

string rock = 1 for inputting 
string paper = 2 for input 
string scissors = 3 for input 

所以我能夠使用int 1,2和3打印字符串輸出。

基本上控制檯應用程序具有用於輸入3個選項：要麼1（巖），2（紙）或3（剪刀）和控制檯需要從生成的隨機數或者1,2-或3並確定您的輸入是否隨機跳動計算機。

string rock = (int)1; 
     string paper; 
     string scissors; 
     int input;   
     Random random = new Random(); 
     int RandomNumber = random.Next(1,4); 
     bool i = true; 

     Console.WriteLine("-- Weapons Menu --"); 
     Console.WriteLine("-------------------"); 
     Console.WriteLine("1] Rock"); 
     Console.WriteLine("2] Paper"); 
     Console.WriteLine("3] Scissors"); 
     Console.WriteLine("Choose Your Weapon [1, 2 or 3]:"); 

     input = int.Parse(Console.ReadLine()); 

     if (input == RandomNumber) 
      Console.WriteLine("You Tied The Computer This Round"); 
      Console.WriteLine("Player Chose ") 

對此的任何幫助將是偉大的，謝謝。我嘗試投出int，但我不能。

Answer 1

使用Dictionary<int, string>：

var choices = new Dictionary<int, string> { {1,"Rock"}, {2,"Paper"}, {3,"Scissors"} }; 

然後，只需訪問正確的元素：

Console.WriteLine("Player Chose {0}", choices[input]); 

你會想要一些驗證周圍到mak確保你不會嘗試訪問不存在的元素，或者用戶沒有輸入非數字值。

Answer 2

1. 使用Int32.TryParse(Console.ReadLine(), out input);鑄件字符串爲整數。
2. 對於鑄造詮釋爲字符串，你必須使用input.ToString();
3. 然後，你可以使用Dictionary<int, string>達到目標。

而在你的代碼的問題是在這條線：string rock = (int)1; 而不是爲這個，你應該給string rock = "1";

Answer 3

 var random = new Random(); 
     while (true) 
     { 
      int RandomNumber = random.Next(1, 4); 
      var userinput = Console.ReadLine(); 
      if (Enumerable.Range(1, 3).Contains(Convert.ToInt16(userinput))) 
       if (userinput == RandomNumber.ToString()) 
        Console.WriteLine("Tied"); 
       else 
        Console.WriteLine("Check and see who won!"); 
      else 
       Console.WriteLine("Try Again!"); 
     }

namespace RockPaperScissors

    class Program

     static void Main(string[] args) 
     { 

      var choices = new Dictionary<int, string> { { 1, "Rock" }, { 2, "Paper" }, { 3, "Scissors" } }; 
      int input; 
      var randomly = new Dictionary<int, string> { { 1, "Rock" }, { 2, "Paper" }, { 3, "Scissors" } }; 

      Random random = new Random(); 
      int RandomNumber = random.Next(1, 4); 
      int Ties; 
      int Wins; 
      int Losses; 



      do

       Console.WriteLine("2] Paper"); 
       Console.WriteLine("3] Scissors"); 
       Console.WriteLine("Choose Your Weapon [1, 2 or 3]:"); 
       input = int.Parse(Console.ReadLine()); 
       if (input == RandomNumber) 
        Console.WriteLine("You Tied The Computer"); 
       Ties++; 
       //Winning 
       if (input == 1 && RandomNumber == 3) 

       Console.WriteLine("You Beat The Computer :)"); 
       Wins++; 

       if (input == 2 && RandomNumber == 1) 

       Console.WriteLine("You Beat The Computer :)"); 
       Wins++; 

       if (input == 3 && RandomNumber == 2) 

       Console.WriteLine("You Beat The Computer :)"); 
       Wins++; 


       //Lossing 
       if (input == 1 && RandomNumber == 2) 

        Console.WriteLine("Sorry You Lost To The Computer :("); 
       Losses++; 

       if (input == 2 && RandomNumber == 3) 

       Console.WriteLine("You Beat The Computer :)"); 
       Losses++; 

       if (input == 3 && RandomNumber == 1) 

       Console.WriteLine("You Beat The Computer :)"); 
       Losses++; 










       Console.WriteLine(string.Format("Player Chose {0} : Computer Chose {1}", choices[input], randomly[RandomNumber])); 
       Console.WriteLine(); 
       Console.WriteLine("<Press Any Key To Continue...>"); 
       Console.WriteLine(); 



       Console.WriteLine("Player Wins  Computer Wins"); 
       Console.WriteLine("----------  --------------"); 
       Console.WriteLine(" {0}    {1}", Wins, Losses); 




       Console.ReadKey(); 
       } 
       while (input != 3) ; 
       Console.WriteLine("Thanks for playing!"); 
      }enter code here 
    } 
    } 



     STILL CANNOT SHOW THE COUNTER WHY
