C＃中的Single.GetHashCode()方法与示例

Single.GetHashCode()方法用于返回此实例的哈希码。

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Single.GetHashCode()方法的用法：

范例1：

// C# program to demonstrate the
// Single.GetHashCode() Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring and initializing value1
        float value1 = 10f;
  
        // getting the HashCode
        // using GetHashCode() method
        int value = value1.GetHashCode();
  
        // Display the HashCode
        Console.WriteLine("HashCode is {0}", value);
    }
}

输出：

HashCode is 1092616192

范例2：

// C# program to demonstrate the
// Single.GetHashCode() Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // calling get() method
        get(5f);
        get(9.5f);
        get(10000f);
        get(2327.5232f);
    }
  
    // defining get() method
    public static void get(float value1)
    {
  
        // getting the HashCode
        // using GetHashCode() method
        int value = value1.GetHashCode();
  
        // Display the HashCode
        Console.WriteLine("HashCode is {0}", value);
    }
}

输出：

HashCode is 1084227584
HashCode is 1092091904
HashCode is 1176256512
HashCode is 1158772831
