This method is used to return an IEnumerator for the Array.
Syntax:
CSHARP
CSharp
public System.Collections.IEnumerator GetEnumerator ();Return Value: This method returns an IEnumerator for the Array. Below programs illustrate the use of Array.GetEnumerator Method: Example 1:
// C# program to demonstrate
// GetEnumerator() method
using System;
using System.Collections;
using System.Collections.Generic;
public class GFG {
// Main Method
public static void Main()
{
// Creating and initializing new the String
String[] myArr = {"Sun", "Mon", "Tue", "Thu"};
// Display the values of the myArr.
Console.Write("Initial Array: ");
// calling the PrintIndexAndValues()
// method to print
PrintIndexAndValues(myArr);
// getting the IEnumerator for the myArr
IEnumerator myEnumerator = myArr.GetEnumerator();
// calling the PrintIndexAndValues()
// method to print
Console.WriteLine("Enumerated value: ");
PrintIndexAndValues(myEnumerator);
}
// Defining the method
// PrintIndexAndValues
public static void PrintIndexAndValues(String[] myArr)
{
for (int i = 0; i < myArr.Length; i++) {
Console.Write("{0} ", myArr[i]);
}
Console.WriteLine();
Console.WriteLine();
}
// Overriding the method
// PrintIndexAndValues
public static void PrintIndexAndValues(IEnumerator myEnumerator)
{
int i = 0;
while ((myEnumerator.MoveNext()) &&
(myEnumerator.Current != null)) {
Console.WriteLine("[{0}] {1}", i++,
myEnumerator.Current);
}
}
}
Output:
Example 2:
Initial Array: Sun Mon Tue Thu Enumerated value: [0] Sun [1] Mon [2] Tue [3] Thu
// C# program to demonstrate
// GetEnumerator() method
// For int value
using System;
using System.Collections;
using System.Collections.Generic;
public class GFG {
// Main Method
public static void Main()
{
// Creating and initializing new the int
int[] myArr = {10, 20, 30, 40};
// Display the values of the myArr.
Console.Write("Initial Array: ");
// calling the PrintIndexAndValues()
// method to print
PrintIndexAndValues(myArr);
// getting the IEnumerator for the myArr
IEnumerator myEnumerator = myArr.GetEnumerator();
// calling the PrintIndexAndValues()
// method to print
Console.WriteLine("Enumerated value: ");
PrintIndexAndValues(myEnumerator);
}
// Defining the method
// PrintIndexAndValues
public static void PrintIndexAndValues(int[] myArr)
{
for (int i = 0; i < myArr.Length; i++) {
Console.Write("{0} ", myArr[i]);
}
Console.WriteLine();
Console.WriteLine();
}
// Overriding the method
// PrintIndexAndValues
public static void PrintIndexAndValues(IEnumerator myEnumerator)
{
int i = 1;
while ((myEnumerator.MoveNext()) &&
(myEnumerator.Current != null)) {
Console.WriteLine("{0}> {1} ", i++,
myEnumerator.Current);
}
}
}
Output:
Reference:
Initial Array: 10 20 30 40 Enumerated value: 1> 10 2> 20 3> 30 4> 40
