+# 猜数字
+
+使用C#编写一个猜数字游戏，以下实现没有错误的代码是？
+
+## 答案
+
+```csharp
+public class Program{
+    public static void Main(string[] args){
+        Random rand = new Random();
+        int success = 0;
+        while(true){
+            int number = rand.Next(0,5);
+            bool replay = false;
+            Console.Write("我想好了一个0-5内的数字，你猜是多少？输入你的猜测或输入q退出: ");
+            while(true){
+                string val = Console.ReadLine();
+                if(val=="q"){
+                    break;
+                }
+                int a = Convert.ToInt32(val);
+                if(a==number){
+                    success +=1;
+                    Console.WriteLine("恭喜你才对了，是否再来一个？[y/n]:");
+                    string ret = Console.ReadLine();
+                    replay = ret=="y";
+                    break;
+                }else{
+                    Console.WriteLine("猜错了，再来一次或输入q退出：");
+                }
+            }
+            if(!replay){
+                break;
+            }
+        }
