C# ArrayList的IsReadOnly属性示例

namespace ConsoleApplication6

{
  class Program
  {
      static void Main(string[] args)

      {
          //创建一个新的ArrayList
          ArrayList days = new ArrayList();
          days.Add("Sunday");

          days.Add("Monday");
          days.Add("Tuesday");
          days.Add("Wednesday");
          //创建 ArrayList的只读副本.

          ArrayList ReadOnly = ArrayList.ReadOnly(days);
          //查看ArrayList是否为只读
          Console.WriteLine("ArrayList days是否为只读: {0}.", days.IsReadOnly);
          Console.WriteLine("ArrayList ReadOnly 是否为只读: {0}.", ReadOnly.IsReadOnly);

      }
  }
}

ArrayList的IsReadOnly属性获取一个值，该值指示arraylist是否是只读的，否则如果是，则返回true否则返回false。
