c语言无法将类型“int”隐式转换为“string”

我要编一个猜数字的游戏，我输入的是： using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Random ran = new Random(); int Randkey = ran.Next(1, 100); Console.WriteLine("请输入你认为正确的整数"); int x = 0; int j; for (j = 1; j <= 8; j++) { x = Convert.ToInt32(Console.ReadLine()); if (x == Randkey) { break; } else if (x != Randkey) { if (x < Randkey) { Console.WriteLine("你输入的值太小了"); continue; } else if (x > Randkey) { Console.WriteLine("你输入的值太大了"); continue; } } } switch ("j") { case 1: Console.WriteLine("你太厉害了"); break; case 2: case 3: case 4: case 5: case 6: case 7: case 8: Console.WriteLine("还差点哦"); break; } Console.Readkey(); } } } 但就是显示无法将类型“int”隐式转换为“string”和“System.Console”并不包含“Readkey”的定义

Answer 1

switch判断不要加双引号，switch(j)
是ReadKey。。不Readkey

Answer 2

switch ("j")

这里的j不应该加引号
