检查 Hashtable 在 C# 中是否有固定大小

要检查 Hashtable 是否有固定大小，代码如下 −

示例

 现场演示

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      Hashtable hash = new Hashtable(10);
      hash.Add("1", "A");
      hash.Add("2", "B");
      hash.Add("3", "C");
      hash.Add("4", "D");
      hash.Add("5","E");
      hash.Add("6", "F");
      hash.Add("7", "G");
      hash.Add("8","H");
      hash.Add("9", "I");
      hash.Add("10", "J");
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);
   }
}

输出

这将产生以下输出 −

Is the Hashtable having fixed size? = False

示例

让我们看另一个例子 −

 现场演示

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      Hashtable hash = new Hashtable();
      hash.Add("One", "Katie");
      hash.Add("Two", "John");
      hash.Add("Three", "Barry");
      hash.Add("Four", "");
      hash.Add("Five","Harry");
      hash.Add("Six", "F");
      hash.Add("Seven", "Tom");
      hash.Add("Eight","Andy");
      hash.Add("Nine", "I");
      hash.Add("Ten", "Tim");
      Console.WriteLine("Hashtable Key and Value pairs...");
      foreach(DictionaryEntry entry in hash){
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);
   }
}

输出

这将产生以下输出 −

Hashtable Key and Value pairs...
One and Katie
Ten and Tim
Five and Harry
Three and Barry
Seven and Tom
Two and John
Four and
Eight and Andy
Nine and I
Six and F
Is the Hashtable having fixed size? = False
