要检查一个Hashtable是否等于另一个Hashtable,代码如下-
using System; using System.Collections; public class Demo { public static void Main(){ Hashtable hash1 = new Hashtable(); hash1.Add("1", "Kevin"); hash1.Add("2", "Steve"); hash1.Add("3", "Tim"); hash1.Add("4", "Gary"); hash1.Add("5", "Kevin"); hash1.Add("6", "Steve"); hash1.Add("7", "Tom"); hash1.Add("8", "Stephen"); Console.WriteLine("HashSet1..."); ICollection key = hash1.Keys; foreach (string k in key) { Console.WriteLine(k + ": " + hash1[k]); } Hashtable hash2 = new Hashtable(); hash2.Add("1", "Kevin"); hash2.Add("2", "Steve"); hash2.Add("3", "John"); hash2.Add("4", "Tim"); key = hash2.Keys; Console.WriteLine("\nHashSet2..."); foreach (string k in key) { Console.WriteLine(k + ": " + hash2[k]); } Console.WriteLine("\nAre both the Hashtable equal? "+(hash1.Equals(hash2))); } }
输出结果
这将产生以下输出-
HashSet1... 1: Kevin 2: Steve 3: Tim 4: Gary 5: Kevin 6: Steve 7: Tom 8: Stephen HashSet2... 1: Kevin 2: Steve 3: John 4: Tim Are both the Hashtable equal? False
让我们看另一个例子-
using System; using System.Collections; public class Demo { public static void Main(){ Hashtable hash1 = new Hashtable(); hash1.Add("1", "Kevin"); hash1.Add("2", "Steve"); hash1.Add("3", "John"); hash1.Add("4", "Tim"); Console.WriteLine("HashSet1..."); ICollection key = hash1.Keys; foreach (string k in key) { Console.WriteLine(k + ": " + hash1[k]); } Hashtable hash2 = new Hashtable(); hash2.Add("1", "Nathan"); hash2.Add("2", "Gary"); hash2.Add("3", "John"); hash2.Add("4", "Tim"); hash2.Add("5", "Steve"); ICollection key2 = hash2.Keys; Console.WriteLine("\nHashSet2..."); foreach (string k in key2) { Console.WriteLine(k + ": " + hash2[k]); } Console.WriteLine("\nAre both the Hashtable equal? "+(hash1.Equals(hash2))); } }
输出结果
这将产生以下输出-
HashSet1... 1: Kevin 2: Steve 3: John 4: Tim HashSet2... 1: Nathan 2: Gary 3: John 4: Tim 5: Steve Are both the Hashtable equal? False
