Question

我之前创建了这个成绩簿代码。我在学习C＃的过程中学会了通过观看视频来编写它。

当硬编码输入等级时，将成绩插入成绩簿是成功的。我正在尝试更新代码，以便我可以从控制台窗口输入成绩而不是硬编码成绩。

以下代码是我目前所拥有的：

class Program
{
    static void Main(string[] args)
    {
        //SpeechSynthesizer synth = new SpeechSynthesizer();
        //synth.Speak("Welcome, to the Grade Book Program.");

        //SpeechSynthesizer justMoreToSay = new SpeechSynthesizer();
        //justMoreToSay.Speak("Okay, Now that we got that out of the way. May you input the Grades please.");


        /*Gradebook book = new Gradebook();
        book.AddGrade(91);
        book.AddGrade(89);
        book.AddGrade(83.5f);
        book.AddGrade(78);
        book.AddGrade(98);
        book.AddGrade(93);
        book.AddGrade(79);
        book.AddGrade(64);
        book.AddGrade(32);
        book.AddGrade(45);
        book.AddGrade(67);
        book.AddGrade(90);
        book.AddGrade(58);
        book.AddGrade(72);
        book.AddGrade(100);
        book.AddGrade(85);*/

        Console.WriteLine("Please go ahead and Listen to the Voice and input the Grades:");

        Gradebook inputValues = new Gradebook();
        inputValues.AddGrade(85);
        inputValues.AddGrade(62);        


        GradeStatistics stats = inputValues.ComputeStatistics();
        //Console.WriteLine(stats.HighestGrade);
        //Console.WriteLine(stats.AverageGrade);
        //Console.WriteLine(stats.LowestGrade);
        Console.WriteLine("The average for this person is {0} and the Highest grade he made is {1} and the Lowest is {2}. If you May please select any character to exit the program!", stats.AverageGrade, stats.HighestGrade, stats.LowestGrade);

}
}

public class Gradebook
{

    public Gradebook()
    {
        grades = new List<float>();
    }

    public GradeStatistics ComputeStatistics()
    {
        GradeStatistics stats = new GradeStatistics();

        float sum = 0;
        foreach (float grade in grades)
        {
            {
                stats.HighestGrade = Math.Max(grade, stats.HighestGrade);
                stats.LowestGrade = Math.Min(grade, stats.LowestGrade);

                sum = sum + grade;                   
            }
        }
        stats.AverageGrade = sum / grades.Count;
        return stats;
    }

    public void AddGrade(float grade)
    {
        grades.Add(grade);
    }

    public List<float> grades;      
}

Answer 1

要从控制台读取行并将其转换为整数，您可以使用读取行并将字符串转换为数字表示形式：

Console.Writeline("Enter Number");

var num = Convert.ToInt32(Console.ReadLine());

在循环中执行此操作，直到您收到用户的某种终止输入，例如-1

Answer 2

试试这个

     for index,rows in df.iterrows():
      cursor.execute("""update result SET Pay_Agent = ? WHERE SEND_AGENT = ?""",df['PAY_AGENT'][rownum],df['SEND_AGENT'][rownum])
     rownum+=1

GradeBook的C＃输入值
