C＃中的Decimal.GetHashCode方法与示例

Decimal.GetHashCode方法用于获取当前Decimal实例的HashCode。

Syntax: public override int GetHashCode ();

Return Value: This method returns a 32-bit signed integer hash code.

下面的程序说明了上面讨论的方法的使用：

范例1：

// C# program to illustrate the
// Decimal.GetHashCode() Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Taking decimal variables
        // having fractional part
        Decimal dec1 = 214748.78549M;
  
        // Getting the hash code for Decimal
        // using GetHashCode() method
        int result = dec1.GetHashCode();
  
        // Display the time
        Console.WriteLine("HashCode for Decimal is: {0}",
                                                 result);
    }
}

输出：

HashCode for Decimal is: 161795526

范例2：

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

输出：

HashCode for -79228162514264337593543950335 is -974127104
HashCode for 79228162514264337593543950335 is 1173356544
