在我为广泛的代码投票之前，我认为有必要找到解决方案。
我已经从之前提供的帮助中对程序代码进行了更改，但我似乎仍然遇到随机数number未被正确比较的问题（我有例子number为'5'且用户的猜测为'5'，但我仍然会收到评论说“你离我很远！再试一次。”这意味着它会落入else if (userinputcalc > 4 | userinputcalc < 10)...
所以，在这个阶段，问题似乎在于number和userinput的比较，导致输出消息混乱。
我可能在这里遗漏了一些明显的东西，尽管我确定这是围绕着比较number和userinput的循环，但我一直在看这个代码并且什么都看不见。
一如既往，非常感谢任何帮助。

好的我觉得这里有很多问题（有些是偏离主题的，但肯定值得一提）..
我不建议使用while循环检查特定输入
例如：
而不是roundCount != 11使用roundCount < 11
然后永远陷入循环的可能性更小
你应该在你的循环之外声明Random，否则你冒着获得相同数字（“随机”）的风险
您在每次猜测后将号码重置为新号码，以便用户无法猜出正确的号码
说到这一切，我认为Math.Abs是正确的，如果你试图找到距离数字的距离..我不会使用少于两个，因为这意味着只有1远离数字的数字答案是“热门”
注意：答案基于问题修订＃5
<强>更新
看起来你似乎没有远，但你仍然会重置每个循环的数字
number = rndm.Next(10) + 1; //Insert here
do
{
//Displays the which round (out of 10) to the user
Console.WriteLine("Round" + roundcount);
guessesleft = 3; //The remaining guesses left for the user
do
{
// Remove this -- number = rndm.Next(10) + 1;

我认为这就是你想要的，请尝试一下：
static int guessesleft;
static Random ran = new Random();
static int MagicNumber;
static string UserInput;
static void Main(string[] args)
{
ConsoleKeyInfo ci = new ConsoleKeyInfo();
do
{
guessesleft = 3;
UserInput = "";
Console.Clear();
string username;
int guesscount = 1;
Console.WriteLine("Welcome to Jackie's Guessing Game!");
Console.WriteLine("");
Console.WriteLine("Please press any button to continue.");
Console.ReadLine();
Console.WriteLine("What's your name?");
username = (Console.ReadLine());
//If you're wondering at all, the "You must guess what it is inthree tries." is intentional, since it was showing double-spaced in the command prompt
Console.WriteLine("Well, " + username + ", I am thinking of a number from 1 to 10. You must guess what it is inthree tries.");
Console.WriteLine("");
MagicNumber = ran.Next(1, 11);
do
{
Console.WriteLine("Please insert your " + guesscount++ + "º guess!");
UserInput = Console.ReadLine().Trim();
if (UserInput == MagicNumber.ToString())
break;
if (Math.Abs(Convert.ToInt32(UserInput) - MagicNumber) < 2)
Console.WriteLine("Hot!!");
else if(Math.Abs(Convert.ToInt32(UserInput) - MagicNumber) < 3)
Console.WriteLine("Warm!!");
Console.WriteLine("No luck , you have " + --guessesleft + "º guesses left!");
Console.WriteLine();
} while (guesscount < 4);
if (guesscount == 4)
Console.WriteLine("Sorry " + username + " no more tries,you lost!");
else
Console.WriteLine("Congratulations your guess with number " + UserInput + " is correct,the number was " + MagicNumber);
Console.WriteLine("Press Q to quit or Enter to Play again!");
ci = Console.ReadKey();
} while (ci.Key != ConsoleKey.Q);
}
