您的代码中有很多错误，但我将通过在它们旁边写注释来回顾我看到的主要错误

Random generator = new Random();
bool truth = true;

//extra semicolon on next line, 
//doesn't make sense to convert a boolean to get your initial max range,
//just give it an initial value, perhaps 0
int MaxRange = Convert.ToInt32(truth); ;
int userguess = 0;

//the generator can't get the correct outputnumber yet because MaxRange hasn't
//been set by the user's input yet
int outputnumber = generator.Next(MaxRange);

do
{
    //this won't get the user input because the parameters in WriteLine() 
    //that come after the string are for inserting into the string, not recieving input
    Console.WriteLine(" Enter a max number you want to guess from!", MaxRange);

    //need to set Console.ReadLine() to a variable for it to be saved
    //should be MaxRange = Console.ReadLine(); (though that will throw an error if the user inputs anything except numbers)
    Console.ReadLine();

    //outputnumber hasn't been set to a true generated number yet
    Console.WriteLine("please make a guess between 1 and {0}", outputnumber);

    //outputnumber could be renamed to be more clear, I would suggest randomNumber
    //userguess is still 0 during the first loop, need to get the user's guess before comparing to the random number
    //also, could simplify these if/else statements to just a couple of them
    //you're also going to need a while loop somewhere in here to continue having the user
    //guess until they get it right
    if (userguess != outputnumber)
    {
        //should use Console.ReadLine()
        userguess = Convert.ToInt32(Console.Read());

        if (userguess < outputnumber)
        {
            Console.WriteLine("That is not correct, Guess again");
            Console.ReadLine();
        }
        if(userguess > outputnumber)
        {
            Console.WriteLine("That is not correct, Guess again");
            Console.ReadLine();
        }
        else if (userguess == outputnumber)
        {
//not indented correctly, missing correct capitalization and missing the right quotes on the string to be wrote
console.writeline("That is correct, the number is {0}, outputnumber);
        }
    }
//should just be while (true);
} while (truth == false);
}

}

Random generator=new Random（）；
布尔真理=真；
//在下一行加上分号，
//将布尔值转换为初始最大范围是没有意义的，
//给它一个初始值，也许是0
int MaxRange=Convert.ToInt32（真值）；
int userguess=0；
//生成器尚未获取正确的输出编号，因为MaxRange尚未获取
//是否已由用户的输入设置
int outputnumber=生成器.Next（最大范围）；
做
{
//这将无法获取用户输入，因为WriteLine（）中的参数
//字符串后面的用于插入字符串，而不是接收输入
WriteLine（“输入您想从中猜出的最大值！”，MaxRange）；
//需要将Console.ReadLine（）设置为要保存的变量
//应为MaxRange=Console.ReadLine（）；（但如果用户输入除数字以外的任何内容，则会引发错误）
Console.ReadLine（）；
//outputnumber尚未设置为真实生成的数字
WriteLine（“请在1和{0}之间进行猜测”，outputnumber）；
//outputnumber可以重命名为更清晰，我建议使用randomNumber
//userguess在第一个循环中仍然为0，在与随机数进行比较之前，需要获得用户的猜测
//此外，可以将这些if/else语句简化为几个
//您还需要在这里的某个地方进行一个while循环，以继续使用该用户
//猜猜看，直到他们猜对为止
if（userguess！=outputnumber）
{
//应该使用Console.ReadLine（）
userguess=Convert.ToInt32（Console.Read（））；
if（userguessoutputnumber）
{
Console.WriteLine（“这不对，再猜一次”）；
Console.ReadLine（）；
}
else if（userguess==outputnumber）
{
//缩进不正确，缺少正确的大写字母和要写入的字符串上缺少正确的引号
writeline（“这是正确的，数字是{0}，outputnumber）；
}
}
//应该只是暂时（真的）；
}而（真=假）；
}

}谢谢大家！我做了一些小的调整，现在几乎完美了。我仍然得到的唯一错误是，当成功运行它时，会询问用户是否希望再次播放。如果他们说是，游戏将使他们从先前选择的最大值开始玩，而不是输入新值
