我试图将您的代码复制到VS中并进行构建，发现了错误消息您提到的如下:
>>
>>
CS0161
'Program.getMenuChoice()': 并非所有代码路径都返回值
由于您的方法"getMenuChoice"被定义为"int"类型，而您没有返回一个'int'值 在此方法的末尾，因此会弹出编译器错误代码'CS0161' .您可以尝试在如下所示的方法中添加返回值，然后此编译器错误将 消失.
Since your method "getMenuChoice" is defined as the ‘int’ type and you did not return a ‘int’ value at the end of this method, so it popups the complier error code ‘CS0161’. You can try to add the return value in the method like the following, then this compiler error will disappear.
public 静态 int
public static int getMenuChoice()
{
{
; 控制台 选择 一个选项号. \ n1.创建字符\ n2.修改字符\ n3.装备武器\ n4.创建新武器\ n5.STATUS \ n6.END"; ) ;
Console.WriteLine("CHOOSE AN OPTION NUMBER. \n1. CREATE CHARACTER\n2. MODIFY CHARACTER\n3. EQUIP WEAPON\n4.CREATE A NEW WEAPON \n5.STATUS\n6.END");
; 字符串 控制台
string choice = Console.ReadLine();
; //声明变量以保存转换后的值
//Declare the variable to hold the converted value
; int
int numChoice;
; //开始循环验证
//Start the loop validation
; 而 int .TryParse(选择， out
while(!int.TryParse(choice, out numChoice))
; { //开始循环
{ //begin loop
; //向用户说明问题
//tell the user the problem
; 控制台 您 \ r \ n请输入数字."
Console.WriteLine("You have typed something other than a number.\r\nPlease enter a number.");
; //捕获新的用户响应并返回到循环的开始
//Catch the new user response and go back to beginning of the loop
; choice = 控制台 //返回
choice = Console.ReadLine(); //loop back
; }
}
; numChoice = 转换
numChoice = Convert.ToInt32(choice);
; 返回
return numChoice;
}
}
