在 C# 中写入行错误

Question

我的任务是在 C# 中创建一个记录保存控制台应用程序，用于添加、查看和删除记录。我需要使用数组、列表或字典（或某种组合）。

我尝试过使用数组和列表，但到目前为止，字典被证明是最成功的（我知道如何在这个程序中最好地使用它们）。照片中是我到目前为止的代码，但是当我提示用户输入信息时出现错误。我尝试了一些不同的修复方法，但都没有奏效。

My Code

    class Patient
    {
        public static string PatientDict;
            public Console.WriteLine("Enter the patient's name: "); 
        string PatientName = Console.ReadLine();
            public Console.WriteLine("Enter the patient's date of birth: "); 
        string PatientDOB = Console.ReadLine();
            public Console.WriteLine("Enter the patient's age: "); 
        string PatientAge = Console.ReadLine();
            public Console.WriteLine("Enter the patient's ailment(s): "); 
        string PatientAilments = Console.ReadLine();
            public Console.WriteLine("Enter the patient's medication(s): "); 
        string PatientMeds = Console.ReadLine();

        string DOB;
        string Age;
        string Ailments;
        string Meds;
    }

您可以像这样使用对象（患者）的列表：

class Program
{
    static void Main(string[] args)
    {
        // Create a new list of patients to store your values
        List<Patient> patients = new List<Patient>();

        // Get user input and store them as variables
        Console.WriteLine("Enter the patients name: ");
        string name = Console.ReadLine();

        Console.WriteLine("Enter the patients date of birth: ");
        string dob = Console.ReadLine();

        Console.WriteLine("Enter the patients age: ");
        int age = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the patients ailment(s): ");
        string ailments = Console.ReadLine();

        Console.WriteLine("Enter the patients medication(s): ");
        string meds = Console.ReadLine();

        Console.WriteLine(); // Empty line


        // Add the given input to the list of patients
        patients.Add(new Patient { patientName = name, patientDOB = dob, patientAilments = ailments, patientMeds = meds, patientAGE = age });


        // Print patients to console output
        foreach (var patient in patients)
        {
            Console.WriteLine("Patients name = {0}", patient.patientName);
            Console.WriteLine("Patients date of birth = {0}", patient.patientDOB);
            Console.WriteLine("Patients age = {0}", patient.patientAGE);
            Console.WriteLine("Patients ailment(s) = {0}", patient.patientAilments);
            Console.WriteLine("Patients medication(s) = {0}", patient.patientMeds);
        }
    }
}

class Patient
{
    public string patientName { get; set; }
    public string patientDOB { get; set; }
    public string patientAilments { get; set; }
    public string patientMeds { get; set; }
    public int patientAGE { get; set; }
}

这只是做你想做的事的众多方法之一。如果您想输入更多患者，只需提示一组新问题并将其添加到列表中即可。

您可能想要重写您的程序。您有多个Main 方法的案例，而Console.WriteLine(...) 不是方法级代码。

看起来您想在 main 方法中执行所有这些操作，因此请考虑：

class Patient 
{
    static void main(string[] args) 
    {
        Console.WriteLine("Enter the patient's name: "); 
        string PatientName = Console.ReadLine();

        Console.WriteLine("Enter the patient's date of birth: "); 
        string PatientDOB = Console.ReadLine();

        Console.WriteLine("Enter the patient's age: "); 
        string PatientAge = Console.ReadLine();

        Console.WriteLine("Enter the patient's ailment(s): "); 
        string PatientAilments = Console.ReadLine();

        Console.WriteLine("Enter the patient's medication(s): "); 
        string PatientMeds = Console.ReadLine();
    }
}
