Example 1:

// C# program to illustrate the
// use of CharEnumerator.Reset()
// Method
using System;

class GFG {

    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "The Sun rises in the East and sets in the West.";

        // Instantiate a CharEnumerator object
        CharEnumerator chEnum = str.GetEnumerator();

        // Printing the string
        while (chEnum.MoveNext())
            Console.Write(chEnum.Current);

        // Reset the CharEnumerator object
        chEnum.Reset();
        Console.WriteLine();

        // Printing the string again
        while (chEnum.MoveNext())
            Console.Write(chEnum.Current);

    {
        // Initialize a string object
        string str = "0 1 2 3 4 5 6 7 8 9";

        // Instantiate a CharEnumerator object
        CharEnumerator chEnum = str.GetEnumerator();

        // Printing the string
        while (chEnum.MoveNext())
            Console.Write(chEnum.Current);

        // Reset the CharEnumerator object
        chEnum.Reset();
        Console.WriteLine();

        // Printing the string again
        while (chEnum.MoveNext())
            Console.Write(chEnum.Current);
