配列の最小要素と最大要素を見つける方法は？

Question

private void button1_Click(object sender, EventArgs e) 
{ 
    int[] m = new int[1000]; 
    int n = textBox1.Lines.Lenght; 
    int i; 
    int k = 0; 
    int sum = 0; 
    int product = 1; 
    int average = 0; 

    for (i = 0; i < n; i++) 
    { 
     try 
     { 
      m[k] = Convert.ToInt32(textBox1.Lines[i]); 
      sum = sum + m[k]; 
      product = product * m[k]; 
      average = sum/n; 
     }  
     catch 
     { 
      MessangeBox.Show("Буквы нельзя!!"); 
      k++; 
     } 
    } 

    label10.Text = n.ToString(); 
    label11.Text = sum.ToString(); 
    label12.Text = product.ToString(); 
    label13.Text = average.ToString();  
} 

Answer 1

次は助けるべきである：

private void button1_Click(object sender, EventArgs e) 
{ 
    int[] m = new int[1000]; 
    int n = textBox1.Lines.Lenght; 
    int i; 
    int k = 0; 
    int sum = 0; 
    int product = 1; 
    int average = 0; 
    int min = Int32.MaxValue; // will hold min value 
    int max = Int32.MinValue; // will hold max value 

    for (i = 0; i < n; i++) 
    { 
     try 
     { 
      m[k] = Convert.ToInt32(textBox1.Lines[i]); 
      sum = sum + m[k]; 
      product = product * m[k]; 
      if (m[k] < min) 
       min = m[k]; 
      if (m[k] > max) 
       max = m[k]; 
     }  
     catch 
     { 
      MessageBox.Show("Буквы нельзя!!"); 
      k++; 
     } 
    } 
    average = sum/n; //Computing average here is more efficient 
    label10.Text = n.ToString(); 
    label11.Text = sum.ToString(); 
    label12.Text = product.ToString(); 
    label13.Text = average.ToString();  
} 

警告を：あなたの配列が空の場合は、デフォルトの最小値と最大値としてInt32.MaxValueをしてInt32.MinValueを持ってしたくない場合があります。あなたはそのケースを別々に扱う必要があります。

Answer 2

using System; 

using System.Collections.Generic; 

using System.Linq; 



int[] m = new int[1000]; 

// fill in the array here ..... 

int min = m.Min(); // find the minimum 

int max = m.Max(); // find the maximum
