IsReadOnly property of ArrayList
In this article I will explain the IsReadOnly property of ArrayList.
Introduction
The IsReadOnly property of ArrayList gets a value indicating whether the ArrayList is read-only, or not if yes then it return true otherwise it return false.
Example
namespace ConsoleApplication6
{
class Program
{
static void Main(string[] args)
{
// Creates a new ArrayList.
ArrayList days = new ArrayList();
days.Add("Sunday");
days.Add("Monday");
days.Add("Tuesday");
days.Add("Wednesday");
// Creates a read-only copy of the ArrayList.
ArrayList ReadOnly = ArrayList.ReadOnly(days);
// Displays whether the ArrayList is read-only or writable.
Console.WriteLine("ArrayList days is ReadOnly or not: {0}.", days.IsReadOnly);
Console.WriteLine("ArrayList ReadOnly is ReadOnly or not: {0}.", ReadOnly.IsReadOnly);
}
}
}
