C# Int64.GetHashCode用法及代碼示例


Int64.GetHashCode方法用於獲取當前Int64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 
// Int64.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Taking Int64 variable 
        // i.e. long data type 
        long s1 = 458732523; 
  
        // Getting the hash code for Int64 
        // using GetHashCode() method 
        int result = s1.GetHashCode(); 
  
        // Display the HashCode  
        Console.WriteLine("HashCode for Int64 is: {0}", 
                                               result); 
    } 
}
輸出:
HashCode for Int64 is: 458732523

範例2:

// C# program to illustrate the 
// Int64.GetHashCode() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // using result() Method 
        result(Int64.MinValue); 
        result(Int64.MaxValue); 
    } 
  
    // result() method 
    public static void result(long val) 
    { 
  
        // using GetHashCode() method 
        int code = val.GetHashCode(); 
  
        // Display the hashcode 
        Console.WriteLine("HashCode for {0} is {1}", 
                                        val, code); 
    } 
}
輸出:
HashCode for -9223372036854775808 is -2147483648
HashCode for 9223372036854775807 is -2147483648
