C# | Check if the StringCollection is read-only
Last Updated :
01 Feb, 2019
StringCollection class is a new addition to the .NET Framework class library that represents a collection of strings. StringCollection class is defined in the System.Collections.Specialized namespace.
StringCollection.IsReadOnly property is used to get a value indicating whether the StringCollection is read-only or not.
Syntax:
public bool IsReadOnly { get; }
Return Value: This property always returns false.
Note:
- A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created.
- Retrieving the value of this property is an O(1) operation.
Example:
using System;
using System.Collections;
using System.Collections.Specialized;
class GFG {
public static void Main()
{
StringCollection myCol = new StringCollection();
String[] myArr = new String[] { "A" , "B" , "C" , "D" , "E" };
myCol.AddRange(myArr);
Console.WriteLine(myCol.IsReadOnly);
}
}
