Hashtable.IsFixedSize Property is used to get a value which indicates whether the Hashtable has a fixed size or not.
Syntax:
CSharp
CSharp
public virtual bool IsFixedSize { get; }
Return Value: This property returns true if the Hashtable has a fixed size otherwise it returns false. The default is false.
Below programs illustrate the above-discussed property:
Example 1:
// C# code to check if Hashtable
// has a fixed size
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Hashtable
Hashtable myTable = new Hashtable();
// Adding elements in Hashtable
myTable.Add("G", "Geeks");
myTable.Add("C", "C#");
myTable.Add("D", "Data Structures");
myTable.Add("Q", "Quiz");
// Checking if Hashtable has a fixed size
// this will return false
Console.WriteLine(myTable.IsFixedSize);
}
}
Output:
Example 2:
False
// C# code to check if Hashtable
// has a fixed size
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Hashtable and
// giving it a size of 4
Hashtable myTable = new Hashtable(4);
// Adding elements in Hashtable
myTable.Add("1", "C");
myTable.Add("2", "C#");
myTable.Add("3", "DS");
myTable.Add("4", "Java");
myTable.Add("5","HTML");
myTable.Add("6", "CSS");
// Checking if Hashtable has a fixed size
// this will return false
Console.WriteLine(myTable.IsFixedSize);
}
}
Output:
Note:
False
- A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but it allows the modification of existing elements.
- A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements. Therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.
- Retrieving the value of this property is an O(1) operation.
