C# | Get a read-only copy of the OrderedDictionary
OrderedDictionary.AsReadOnly method returns a read-only copy of the current OrderedDictionary collection.
Syntax:
public System.Collections.Specialized.OrderedDictionary AsReadOnly ();
Return Value: A read-only copy of the current OrderedDictionary collection.
Below given are some examples to understand the implementation in a better way:
Example 1:
// C# code to get a read-only // copy of the OrderedDictionary using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver method public static void Main() { // Creating a orderedDictionary named myDict OrderedDictionary myDict = new OrderedDictionary(); // Adding key and value in myDict myDict.Add( "key1" , "value1" ); myDict.Add( "key2" , "value2" ); myDict.Add( "key3" , "value3" ); myDict.Add( "key4" , "value4" ); myDict.Add( "key5" , "value5" ); // To Get a read-only copy of // the OrderedDictionary OrderedDictionary myDict_1 = myDict.AsReadOnly(); // Checking if myDict_1 is read-only Console.WriteLine(myDict_1.IsReadOnly); } } |
Output:
True
Example 2:
// C# code to get a read-only // copy of the OrderedDictionary using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver method public static void Main() { // Creating a orderedDictionary named myDict OrderedDictionary myDict = new OrderedDictionary(); // Adding key and value in myDict myDict.Add( "A" , "Apple" ); myDict.Add( "B" , "Banana" ); myDict.Add( "C" , "Cat" ); myDict.Add( "D" , "Dog" ); // To Get a read-only copy of // the OrderedDictionary OrderedDictionary myDict_1 = myDict.AsReadOnly(); // Checking if myDict_1 is read-only Console.WriteLine(myDict_1.IsReadOnly); } } |
Output:
True
Note: The AsReadOnly method creates a read-only wrapper around the current OrderedDictionary collection. Changes made to the OrderedDictionary collection are reflected in the read-only copy.
