Question

我正在研究考试应用程序（c＃console应用程序）

应用程序要求用户输入其名称，我希望应用程序读取该用户的名称和根据我存储在对象中的详细信息打印用户的详细信息

例如：如果用户的名称与此对象中的名称匹配：

students s3 = new students("Dee", "Scott", "Computing", 100m, 66.6m);

如何打印此用户的详细信息。

我有一个单独的方法打印出用户的详细信息

public string gradeDetails {
        get { return FirstName + LastName + Course + FinalGrade; }
    }

我无法弄清楚如何将用户输入与相应的对象进行匹配。

Answer 1

您可以使用Console.Readline()方法

   public static void Main()
   {
      string line;
      Console.WriteLine("Enter one or more lines of text (press CTRL+Z to exit):");
      Console.WriteLine();
      do { 
         Console.Write("   ");
         line = Console.ReadLine();
         if (line != null) 
            Console.WriteLine("      " + line);
      } while (line != null);

Answer 2

Console.ReadLine();
Console.WriteLine(); or Console.Write();

我不确定这是不是你要问的，但那些是读写的电话。

这个信息很容易谷歌。

以下示例将执行您的要求。如果您对我使用的代码有任何疑问，请随时提出。

class Student
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Course { get; set; }
    public decimal FinalGrade { get; set; }

    public Student(string firstName,
                   string lastName,
                   string course)
    {
        FirstName = firstName;
        LastName = lastName;
        Course = course;
        FinalGrade = 0;
    }

    // This will first call the constructor above and then continue.
    public Student(string firstName,
                   string lastName,
                   string course,
                   decimal finalGrade) : this(firstName, lastName, course)
    {
        FinalGrade = finalGrade;
    }

    // By overriding ToString we can use Console.WriteLine(student) directly.
    public override string ToString()
    {
        return string.Format(@"FirstName: {0}, LastName: {1}, Course: {2}, FinalGrade: {3}",
                             FirstName,
                             LastName,
                             Course,
                             FinalGrade);
    }
}

class Program
{
    static void Main(string[] args)
    {
        // Create our students.
        List<Student> students = new List<Student>
                                 {
                                     new Student("John", "Test", "Computing"),
                                     new Student("Tim", "Test", "Computing", 8.25m)
                                 };

        string user = "";
        do
        {
            Console.Clear();
            Console.WriteLine("Please enter the name of the student:");
            user = Console.ReadLine();
            if (user.Equals("exit", StringComparison.OrdinalIgnoreCase))
                break;

            // Find the student or return null.
            Student student = students.FirstOrDefault(s => s.FirstName.Equals(user, StringComparison.OrdinalIgnoreCase));

            if (student != null)
            {
                Console.WriteLine("Student info:");
                Console.WriteLine(student);
            }
            else
            {
                Console.WriteLine("Student '" + user + "' not found.");
            }
            Console.WriteLine();

            // Wait until a key is pressed.
            Console.WriteLine("Press a key to continue..");
            Console.ReadKey(true);
        } while (true);
    }
}

Answer 4

做这样的事情：创建一个名为Student的课程：

 public class Student
    {
        public string Fname { get; set; }
        public string LName { get; set; }
        public string Course { get; set; }
        public string FinalGrade { get; set; }

    }

然后这样做

class Program
    {

        static void Main(string[] args)
        {



            Console.WriteLine("Enter you name:");
            string name = Console.ReadLine();

            Console.WriteLine(gradeDetails(name));

            Console.ReadLine();
        }

        public static string gradeDetails(string name)
        {
             List<Student> students = new List<Student>()
                {
                    new Student{ Fname = "Scott",LName ="Dee",Course = "Computing", FinalGrade = "66.66m"},
                    new Student{Fname = "Joe",LName = "Don",Course = "Chemestry", FinalGrade = "80.77m"}
                };

            var student = students.SingleOrDefault(s => s.LName.ToLower() == name.ToLower());

            if (student!=null)
            {
                return student.Fname + "" + student.LName + "" + student.Course + "" + student.FinalGrade;
            }

            return string.Empty;
        }
    }

Answer 5

询问用户输入名称和打印名称

 using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;

    namespace stackoverflow1
    {
        class Program
        {
            static void Main(string[] args)
            {
                string name;

                Console.WriteLine("Enter your name : ");
                name = Console.ReadLine();

                Console.WriteLine("Hello " + name + " , Welcome to OOP!");

                Console.ReadKey();
            }
        }
    }
