C#循环录入4名员工信息并按销售额排序实现咨询

Hey there! No worries about the code structure—everyone starts learning by experimenting, and your single-worker implementation is a solid starting point. Let's fix the loop issue and add the sorting functionality you need.

Step 1: Create a Worker Class to Organize Data #

First, let's wrap all worker details into a class. This makes it way easier to store multiple workers and sort them later.

// Define a class to hold all worker information
public class Worker
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string District { get; set; }
    public int Sales { get; set; }
    public int MonthlyPay { get; set; } // We'll calculate this later
}

Step 2: Use a Loop to Enter 4 Workers' Data #

We'll use a for loop to run 4 times, collecting data each time and adding the worker to a list.

// Create a list to store all workers
List<Worker> workers = new List<Worker>();
int basePay = 1000;

for (int i = 0; i < 4; i++)
{
    Console.WriteLine($"--- Enter details for Worker {i+1} ---");
    
    Worker newWorker = new Worker();
    
    Console.Write("What is the first- and lastname of the worker: ");
    newWorker.Name = Console.ReadLine();
    
    Console.Write("What is the age of the worker: ");
    // Use int.TryParse to avoid errors if user enters non-numeric values (better practice!)
    int.TryParse(Console.ReadLine(), out newWorker.Age);
    
    Console.Write("What district does the worker work at: ");
    newWorker.District = Console.ReadLine();
    
    Console.Write("How many sales has the worker done: ");
    int.TryParse(Console.ReadLine(), out newWorker.Sales);
    
    // Calculate monthly pay based on sales
    newWorker.MonthlyPay = basePay;
    if (newWorker.Sales > 199)
    {
        newWorker.MonthlyPay += newWorker.Sales * 4;
    }
    else if (newWorker.Sales >= 100)
    {
        newWorker.MonthlyPay += newWorker.Sales * 3;
    }
    else if (newWorker.Sales >= 50)
    {
        newWorker.MonthlyPay += newWorker.Sales * 2;
    }
    else
    {
        newWorker.MonthlyPay += newWorker.Sales;
    }
    
    // Add the new worker to our list
    workers.Add(newWorker);
    Console.WriteLine("\n");
}

Step 3: Sort Workers by Sales #

Now we'll sort the list of workers by their sales count. We can use LINQ's OrderByDescending to get highest sales first (or OrderBy for lowest first).

// Sort workers from highest sales to lowest
var sortedWorkers = workers.OrderByDescending(w => w.Sales).ToList();

Step 4: Display the Sorted Results #

Finally, let's print out all sorted workers with their details and pay:

Console.WriteLine("--- Sorted Workers by Sales (Highest to Lowest) ---");
Console.WriteLine("Name\t\tAge\tDistrict\tSales\tMonthly Pay");
Console.WriteLine("-----------------------------------------------------");

foreach (Worker worker in sortedWorkers)
{
    // Calculate level for display
    string level;
    if (worker.Sales > 199) level = "Level 4";
    else if (worker.Sales >= 100) level = "Level 3";
    else if (worker.Sales >= 50) level = "Level 2";
    else level = "Level 1";
    
    Console.WriteLine($"{worker.Name}\t\t{worker.Age}\t{worker.District}\t\t{worker.Sales}\t{worker.MonthlyPay}kr ({level})");
}

Key Improvements Explained #

• Worker Class: Groups all related data together, making it easy to manage and sort.
• List Storage: Lets us keep track of multiple workers instead of just one.
• Loop: The for loop runs exactly 4 times, so you don't have to repeat the code 4 times manually.
• Error Handling: Used int.TryParse to prevent crashes if the user enters non-numeric values (a good habit to learn early!).
• Sorting: LINQ makes sorting a list super straightforward with OrderByDescending.

Don't hesitate to ask if any part doesn't make sense—learning takes time, and you're doing great!
