法律如何在 C# 中获取 Hashtable 特定键的哈希码？
获取 Hashtable 特定键的哈希码的代码如下 −
实例
using System; using System.Collections; public class HashCode : Hashtable { public static void Main(string[] args) { HashCode hash = new HashCode(); hash.Add("A", "Jacob"); hash.Add("B", "Mark"); hash.Add("C", "Tom"); hash.Add("D", "Nathan"); hash.Add("E", "Tim"); hash.Add("F", "John"); hash.Add("G", "Gary"); Console.WriteLine("Key and Value pairs..."); foreach(DictionaryEntry entry in hash) { Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } Console.Write("HashCode for key D =" + (hash.GetHash("D")) ); } }
输出
会产生以下输出 −
Key and Value pairs... G and Gary A and Jacob B and Mark C and Tom D and Nathan E and Tim F and John HashCode for key D =-842352676

我们来看另一个例子 −
using System; using System.Collections; public class HashCode : Hashtable { public static void Main(string[] args) { HashCode hash = new HashCode(); hash.Add('1', "One"); hash.Add('2', "Two"); hash.Add('3', "Three"); hash.Add('4', "Four"); Console.WriteLine("Key and Value pairs..."); foreach(DictionaryEntry entry in hash) { Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } Console.WriteLine("HashCode for key 1 = " + (hash.GetHash('1'))); Console.WriteLine("HashCode for key 2 = " + (hash.GetHash('2'))); Console.WriteLine("HashCode for key 3 = " + (hash.GetHash('3'))); Console.WriteLine("HashCode for key 4 = " + (hash.GetHash('4'))); } }
输出
会产生以下输出 −
Key and Value pairs... 3 and Three 2 and Two 4 and Four 1 and One HashCode for key 1 = 3211313 HashCode for key 2 = 3276850 HashCode for key 3 = 3342387 HashCode for key 4 = 3407924
