public class Score_Zqj
{
    public string Name{get;set;}
    public string ClassName{get;set;}
    public string Subject{get;set;}
    public double Score{get;private set;}

    public bool IsEffectiveScore
    {
        get
        {
            return Score >= 0 && Score <= 100
        }
    }

    public Score_Zqj()
    {
    }

    public Score_Zqj(string name, strign className,string subject)
    {
        Name = name;
        ClassName = className;
        Subject = subject;
    }

    public void InputScore()
    {
        double score = 0;
        if(double.TryParse(Console.ReadLine(),out score))
        {
            Score = score;

            if(!IsEffectiveScore)
                Score = 0;
        }
    }

    public void UpdateScore()
    {
        double score = 0;
        Console.WriteLine("please input score: ");
        if (double.TryParse(Console.ReadLine(), out score))
        {
            Score = score;

            while (!IsEffectiveScore)
            {
                 Console.WriteLine("Invalid score, please input again");
                    UpdateScore();
            }
        }
    }

    public void OutputScore()
    {
        string outputMessage = "{0} is in Class {1}, {0}'s {2} score is {3} points.";
        Console.WriteLine(string.Format(outputMessage, Name, ClassName, Subject, Score));
    }
}上述例子只是为了让你直观的看到效果实际上UpdateScore里面不应该有输入不对重复输入的逻辑再给你一个例子
public class Score_Zqj
    {
        public string Name { get; set; }

        public string ClassName { get; set; }

        public string Subject { get; set; }

        public double Score { get; private set; }

        public bool IsEffectiveScore
        {
            get
            {
                return 0 <= Score && Score <= 100;
            }
        }

        public Score_Zqj()
        {

        }

        public Score_Zqj(string name, string className, string subject)
        {
            Name = name;
            ClassName = className;
            Subject = subject;
        }

        public void InputScore(double inputScore)
        {

            Score = inputScore;

            if (!IsEffectiveScore)
            {
                Score = 0;
            }
        }

        public bool UpdateScore(double inputScore)
        {
            bool result = true;
            Score = inputScore;

            if (!IsEffectiveScore)
            {
                result = false;
            }

            return result;
        }

        public void OutputScore()
        {
            string outputMessage = "{0} is in Class {1}, {0}'s {2} score is {3} points.";
            Console.WriteLine(string.Format(outputMessage, Name, ClassName, Subject, Score));
        }

    }你在调用UpdateScore方法的地方加逻辑判断只要返回值不为真就需要一直输入直到对为止下面给你补上调用吧
static void main(string[] args)
{
    Score_Zqj[] szs = new Score_Zqj[5];

    for (int i = 0; i < szs.Length; i++)
    {
        Score_Zqj sz = new Score_Zqj("zhangsan" + i, "3(2)", "english");
        double score = 0;
        if (double.TryParse(Console.ReadLine(), out score))
        {
            while (!sz.UpdateScore(score))
            {
                  double.TryParse(Console.ReadLine(), out score);
            }
         }

         szs[i] = sz;
     }

     foreach (Score_Zqj sz in szs)
     {
          sz.OutputScore();
     }
}
