C#中的Int64.GetHashCode方法与示例
C#中的Int64.GetHashCode()方法用于返回此实例的哈希码。
语法
以下是语法-
public override int GetHashCode ();
示例
现在让我们看一个实现Int64.GetHashCode()方法的示例-
using System;
public class Demo {
public static void Main(){
long val1 = 8768768768;
long val2 = 7889765555;
Console.WriteLine("Value1 = "+val1);
Console.WriteLine("Value2 = "+val2);
Console.WriteLine("Are they equal? = "+val1.Equals(val2));
Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode());
Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
}
}输出结果
这将产生以下输出-
Value1 = 8768768768 Value2 = 7889765555 Are they equal? = False Value1 (HashCode) = 178834178 Value2 (HashCode) = -700169038
示例
现在让我们看另一个示例来实现Int64.GetHashCode()方法-
using System;
public class Demo {
public static void Main(){
long val1 = 0;
long val2 = Int64.MaxValue;
Console.WriteLine("Value1 = "+val1);
Console.WriteLine("Value2 = "+val2);
Console.WriteLine("Are they equal? = "+val1.Equals(val2));
Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode());
Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode());
}
}输出结果
这将产生以下输出-
Value1 = 0 Value2 = 9223372036854775807 Are they equal? = False Value1 (HashCode) = 0 Value2 (HashCode) = -2147483648
