This method is used to return an IEnumerator for the Array.
Syntax:
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:
Initial Array: Sun Mon Tue Thu Enumerated value: [0] Sun [1] Mon [2] Tue [3] Thu
Example 2:
// 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:
Initial Array: 10 20 30 40 Enumerated value: 1> 10 2> 20 3> 30 4> 40
