Double.GetHashCode()方法用于返回此实例的哈希码。
用法： public override int GetHashCode ();
返回值：此方法返回32位有符号整数哈希码。
下面的程序说明Double.GetHashCode()方法的使用：
示例1:
// C# program to demonstrate the
// Double.GetHashCode() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
double value1 = 10d;
// getting the HashCode
// using GetHashCode() method
int value = value1.GetHashCode();
// Display the HashCode
Console.WriteLine("HashCode is {0}", value);
}
}
输出：
HashCode is 1076101120
示例2:
// C# program to demonstrate the
// Double.Equals(Double)
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(5d);
get(5.5d);
get(10d);
get(7.5d);
}
// defining get() method
public static void get(double value1)
{
// getting the HashCode
// using GetHashCode() method
int value = value1.GetHashCode();
// Display the HashCode
Console.WriteLine("HashCode is {0}", value);
}
}
输出：
HashCode is 1075052544 HashCode is 1075183616 HashCode is 1076101120 HashCode is 1075707904
