入力テキストボックスとプレースバリュー結果のテキストボックスの最高値と最低値を取得

Question

テキストボックスからランナータイムを取得し、結果のテキストボックスに降順で結果を配置しようとしています。注文は1位、2位、3位にする必要があります。私は条件文を使ってみましたが、たくさんのコードを使わなければならないようです。 1位、2位、3位を決める方法を見つける別の方法はありますか？ここに私のコードです。

namespace Calculate Runner Time 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 

      InitializeComponent(); 

     } 

     private void Calculatebutton_Click(object sender, EventArgs e) 
     { 

      string Runner1Name; 
      string Runner2Name; 
      string Runner3Name; 

      double Runner1Time; 
      double Runner2Time; 
      double Runner3Time; 

      //double FirstPlace; 
      //double SecondPlace; 
      //double ThirdPlace; 

      //get runner names 
      Runner1Name = Runner1NametextBox.Text; 
      Runner2Name = Runner2NametextBox.Text; 
      Runner3Name = Runner3NametextBox.Text; 



      //check if Runner1Name is empty 
      if (string.IsNullOrEmpty(Runner1Name)) 
      { 
       MessageBox.Show("The Runner 1 Name cannot be empty ", "Invalid Runner Name", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
      } 

      //check if Runner1Name is empty 
      else if (string.IsNullOrEmpty(Runner2Name)) 
      { 
       MessageBox.Show("The Runner 2 Name cannot be empty ", "Invalid Runner Name", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
      } 

      else if (string.IsNullOrEmpty(Runner3Name)) 
      { 
       MessageBox.Show("The Runner 3 Name cannot be empty ", "Invalid Runner Name", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
      } 

      else if (!double.TryParse(Runner1TimetextBox.Text, out Runner1Time)) 

      { 
       MessageBox.Show("Please Input a Positive number for Runner 1", "Invalid Input", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
      } 

      else if (!double.TryParse(Runner2TimetextBox.Text, out Runner2Time)) 
      {

       MessageBoxButtons.OK, MessageBoxIcon.Error); 
      } 

      //else if (Runner1Time == Runner2Time & Runner1Time == Runner3Time) 
      //{ 
      // FirstPlacetextBox.Text = Runner1Name.ToString(); 
      // FirstPlacetextBox.Text = Runner2Name.ToString(); 
      // FirstPlacetextBox.Text = Runner3Name.ToString(); 
      //} 

      else if (Runner1Time >= Runner2Time & Runner1Time >= Runner3Time)    
      { 
       FirstPlacetextBox.Text = Runner1Name.ToString();       
      } 

      else if (Runner2Time >= Runner1Time & Runner2Time >= Runner3Time) 
      { 
       FirstPlacetextBox.Text = Runner2Name.ToString(); 
      }

      {   

       SecondPlacetextBox.Text = Runner1Name.ToString(); 
      } 

      else if (Runner2Time <= Runner1Time & Runner2Time <= Runner3Time) 
      {

      Runner2NametextBox.Text = string.Empty;

      //clear runnertime 
      Runner1TimetextBox.Text = ""; 
      Runner2TimetextBox.Text = ""; 
      Runner3TimetextBox.Text = ""; 


      //clears result textbox 
      FirstPlacetextBox.Text = ""; 
      SecondPlacetextBox.Text = ""; 
      ThirdPlacetextBox.Text = ""; 

Answer 1

あなたはこの

Dictionary<string, double> results = new Dictionary<string, double>(); 

// Add your runners. 
results.Add(Runner1Name, Runner1Time); 
results.Add(Runner2Name , Runner2Time); 
results.Add(Runner3Name , Runner2Time); 

var bestTime = results.Min(item => item.Value); 
var worstTime = results.Max(item => item.Value); 
foreach (var item in results) 
{ 
    if (item.Value == bestTime) 
    { 
     Console.WriteLine($"First place {item.Key}"); 
     continue; 
    } 
    if (item.Value == worstTime) 
    { 
     Console.WriteLine($"Third place {item.Key}"); 
     continue; 
    } 
    Console.WriteLine($"Second place {item.Key}"); 
}
