Copy OrderedDictionary elements to Array instance at the specified index in C#
To copy OrderedDictionary elements to Array instance at the specified index, the code is as follows −
Example
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict = new OrderedDictionary ();
dict.Add(1, "Harry");
dict.Add(2, "Mark");
dict.Add(3, "John");
dict.Add(4, "Jacob");
dict.Add(5, "Tim");
Console.WriteLine("OrderedDictionary elements...");
foreach(DictionaryEntry d in dict){
Console.WriteLine(d.Key + " " + d.Value);
}
DictionaryEntry[] dictArr = new DictionaryEntry[dict.Count];
Console.WriteLine("
Copying to Array instance...");
dict.CopyTo(dictArr, 0);
for (int i = 0; i < dictArr.Length; i++) {
Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);
}
}
}Output
This will produce the following output −
OrderedDictionary elements... 1 Harry 2 Mark 3 John 4 Jacob 5 Tim Copying to Array instance... Key = 5, Value = Tim Key = 4, Value = Jacob Key = 3, Value = John Key = 2, Value = Mark Key = 1, Value = Harry
Example
Let us now see another example:
using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
OrderedDictionary dict = new OrderedDictionary ();
dict.Add(1, 10);
dict.Add(2, 20);
Console.WriteLine("OrderedDictionary elements...");
foreach(DictionaryEntry d in dict){
Console.WriteLine(d.Key + " " + d.Value);
}
DictionaryEntry[] dictArr = new DictionaryEntry[5];
Console.WriteLine("
Copying to Array instance...");
dict.CopyTo(dictArr, 0);
for (int i = 0; i < dictArr.Length; i++) {
Console.WriteLine("Key = "+dictArr[i].Key + ", Value = " + dictArr[i].Value);
}
}
}Output
This will produce the following output −
OrderedDictionary elements... 1 10 2 20 Copying to Array instance... Key = 2, Value = 20 Key = 1, Value = 10 Key = , Value = Key = , Value = Key = , Value =
