检查Hashtable在C#中是否具有固定大小
要检查Hashtable是否具有固定大小，代码如下-
示例
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);
}
}输出结果
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-
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);
}
}输出结果
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
