我正在制作一個界面來將角色和恐龍變數存盤到串列中，然后在被詢問時將它們列印出來。
有一個 switch 陳述句來獲取用戶的輸入：
- 案例1：該功能允許用戶輸入字符資料，然后將其放入串列中。
- 案例2：該功能允許用戶輸入恐龍資料，然后將其放入串列中。
- 案例 3 該函式列印每個串列中的物件。但是，每當我運行它時，它都不會列印任何東西，也不會出現任何錯誤。如果我運行代碼以在各自的情況下列印每個串列，那么它們列印得很好。
class Program
{
static void Main()
{
int NumAns;
Console.WriteLine("*1. Character Creator ");
Console.WriteLine("*2. Dinosaur Creator ");
Console.WriteLine("*3. Display ");
Console.WriteLine("");
Console.WriteLine("Specify your menu choice");
string NumAnsString = Console.ReadLine();
NumAns = Convert.ToInt32(NumAnsString);
MenuChosen(NumAns);
}
static void MenuChosen(int selection)
{
List<Dinosaur> Dinosaur_l = new List<Dinosaur>();
List<Character> CharSave = new List<Character>();
Character character = new Character();
Dinosaur dinosaur = new Dinosaur();
switch (selection)
{
case 1:
Console.WriteLine("You chose Character Creator");
character.CharacterVal();
CharSave.Add(new Character
{
name = character.name,
age = character.age,
height = character.height,
hair = character.hair,
eyes = character.eyes,
glasses = character.glasses
});
Main();
break;
case 2:
Console.WriteLine("You chose Dinosaurs");
dinosaur.DinoVal();
Dinosaur_l.Add(new Dinosaur
{
name = dinosaur.name,
species = dinosaur.species,
diet = dinosaur.diet,
sex = dinosaur.sex
});
Main();
break;
case 3:
Console.WriteLine(" ");
Console.WriteLine("Character: ");
Console.WriteLine(" ");
foreach (Character chara in CharSave)
{
Console.WriteLine(chara.name);
Console.WriteLine(chara.age);
Console.WriteLine(chara.height);
Console.WriteLine(chara.hair);
Console.WriteLine(chara.eyes);
Console.WriteLine(chara.glasses);
}
Console.WriteLine(" ");
Console.WriteLine("Dinosaurs: ");
Console.WriteLine(" ");
foreach (Dinosaur Dino in Dinosaur_l)
{
Console.WriteLine(Dino.name);
Console.WriteLine(Dino.species);
Console.WriteLine(Dino.diet);
Console.WriteLine(Dino.sex);
}
Console.WriteLine(" ");
Main();
break;
}
}
}
這是用于 CharacterVal 函式的代碼
public class Character
{
public string name;
public string age;
public string height;
public string hair;
public string eyes;
public string glasses;
public int charID = 0;
int x = 1;
public void CharacterVal()
{
charID ;
Console.WriteLine("Name your Character: ");
name = Console.ReadLine();
Console.WriteLine("How old is " name "? :");
age = Console.ReadLine();
Console.WriteLine("How tall is " name "?: ");
height = Console.ReadLine();
Console.WriteLine("What colour is " name "'s hair ?: ");
hair = Console.ReadLine();
Console.WriteLine("What colour is " name "'s eyes ?: ");
eyes = Console.ReadLine();
GlassesCheck();
}
public void GlassesCheck()
{
Console.WriteLine("does " name " wear glasses? (yes/no): ");
while (x == 1)
{
glasses = Console.ReadLine();
if(glasses =="yes")
{
x = 2;
}
else if(glasses == "no")
{
x = 2;
}
else
{
x = 1;
Console.WriteLine("'" glasses "' is not a valid answer, does " name " wear glasses? (yes/no): ");
}
}
}
}
這是用于 DinoVal 函式的代碼
public class Dinosaur
{
public string species;
public string diet;
public string sex;
public string name;
public void DinoVal()
{
Console.WriteLine("***************************");
Console.WriteLine("*Choose a Dinosaur *");
Console.WriteLine("* *");
Console.WriteLine("*1. Alvarezsaurus *");
Console.WriteLine("*2. Avimimus *");
Console.WriteLine("*3. Bactrosaurus *");
Console.WriteLine("*4. Baryonyx *");
Console.WriteLine("*5. Coloradisaurus *");
Console.WriteLine("*6. Chungkingosaurus *");
Console.WriteLine("***************************");
int Selection = Convert.ToInt32(Console.ReadLine());
switch (Selection)
{
case 1:
Console.WriteLine("you have chosen the Alvarezsaurus");
Console.WriteLine("This is a Carnivore ");
species = "Alvarezsaurus";
diet = "Carnivore";
break;
case 2:
Console.WriteLine("you have chosen the Avimimus");
Console.WriteLine("This is an Omnivore ");
species = "Avimimus";
diet = "Omnivore";
break;
case 3:
Console.WriteLine("you have chosen the Bactrosaurus");
Console.WriteLine("This is a Herbivore ");
species = "Bactrosaurus";
diet = "Herbivore";
break;
case 4:
Console.WriteLine("you have chosen the Baryonyx");
Console.WriteLine("This is a Carnivore ");
species = "Baryonyx";
diet = "Carnivore";
break;
case 5:
Console.WriteLine("you have chosen the Coloradisaurus");
Console.WriteLine("This is an Omnivore ");
species = "Coloradisaurus";
diet = "Omnivore";
break;
case 6:
Console.WriteLine("you have chosen the Chungkingosaurus");
Console.WriteLine("This is a Herbivore ");
species = "Chungkingosaurus";
diet = "Herbivore";
break;
}
Console.WriteLine("Please choose the dinosaurs sex");
Console.WriteLine("1.Male");
Console.WriteLine("2.Female");
int GenderChoice = Convert.ToInt32(Console.ReadLine());
switch (GenderChoice)
{
case 1:
Console.WriteLine("the dinosaur will be male");
sex = "Male";
break;
case 2:
Console.WriteLine("the dinosaur will be female");
sex = "Female";
break;
}
Console.WriteLine("What name will you give this " sex " " species " ?:");
name = Console.ReadLine();
}
}
我試過搬家
CharSave.Add(new Character
{
name = character.name,
age = character.age,
height = character.height,
hair = character.hair,
eyes = character.eyes,
glasses = character.glasses
});
進入案例 3，但所做的只是為每個物件列印空格
uj5u.com熱心網友回復：
存盤字符和恐龍的串列需要在MenuChosen方法之外，因為每次撰寫代碼時都會MenuChosen創建新串列。
你可以：
class Program
{
static List<Dinosaur> Dinosaur_l = new List<Dinosaur>();
static List<Character> CharSave = new List<Character>();
}
主選單 -> 選單選擇 -> 主選單 -> 選單選擇 -> ...
因為你構建的方式（Main 呼叫 MenuChosen 呼叫 Main 等等）你的代碼 - 如果你運行游戲足夠長的時間 - 最終會導致堆疊溢位。
為避免這種情況，您可以回圈運行代碼：
Main()
{
while (true) // or selection was 'Quit', etc.
{
your code here
}
// Remove calls to 'Main' from the switch statement.
