C# Int32.GetHashCode用法及代碼示例

Int32.GetHashCode方法用於獲取當前Int32實例的HashCode。

用法： public override int GetHashCode ();

返回值：此方法返回32位有符號整數哈希碼。

以下示例程序旨在說明上麵討論的方法的使用：

範例1：

// C# program to illustrate the 
// Int32.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Taking Int32 variable 
        int val = 32523; 
  
        // Getting the hash code for Int32 
        // using GetHashCode() method 
        int result = val.GetHashCode(); 
  
        // Display the hashcode 
        Console.WriteLine("HashCode for Int32 is: {0}", 
                                               result); 
    } 
}

輸出：

HashCode for Int32 is: 32523

範例2：

// C# program to illustrate the 
// Int32.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // using result() Method 
        result(Int32.MinValue); 
        result(Int32.MaxValue); 
    } 
  
    // result() method 
    public static void result(int val) 
    { 
  
        // using GetHashCode() method 
        int code = val.GetHashCode(); 
  
        // Display the hashcode 
        Console.WriteLine("HashCode for {0} is {1}", 
                                         val, code); 
    } 
}

輸出：

HashCode for -2147483648 is -2147483648
HashCode for 2147483647 is 2147483647
