C#中的Int32.GetHashCode方法与示例
C#中的Int32.GetHashCode()方法用于返回当前实例的哈希码。
语法
以下是语法-
public override int GetHashCode ();
示例
现在让我们看一个实现Int32.GetHashCode()方法的示例-
using System; public class Demo { public static void Main(){ int val1 = Int32.MinValue; int val2 = 300; Console.WriteLine("Value1 = "+val1); Console.WriteLine("Value2 = "+val2); Console.WriteLine("Are they equal? = "+val1.Equals(val2)); Console.WriteLine("HashCode for Value1 = "+val1.GetHashCode()); Console.WriteLine("HashCode for Value2 = "+val2.GetHashCode()); } }
输出结果
这将产生以下输出-
Value1 = -2147483648 Value2 = 300 Are they equal? = False HashCode for Value1 = -2147483648 HashCode for Value2 = 300
示例
现在让我们来看另一个实现Int32.GetHashCode()方法的示例-
using System; public class Demo { public static void Main(){ int val1 = 50; int val2 = 50; Console.WriteLine("Value1 = "+val1); Console.WriteLine("Value2 = "+val2); Console.WriteLine("Are they equal? = "+val1.Equals(val2)); Console.WriteLine("HashCode for Value1 = "+val1.GetHashCode()); Console.WriteLine("HashCode for Value2 = "+val2.GetHashCode()); } }
输出结果
这将产生以下输出-
Value1 = 50 Value2 = 50 Are they equal? = True HashCode for Value1 = 50 HashCode for Value2 = 50
