    IEnumerable 

    IEnumerable is an interface which is implemented to support the ForEach semantics of Microsoft Visual Basic. It contains GetEnumerator method therefore exposes the enumerator, which in turn performs a simple iteration over a collection of specified type.

    Syntax of IEnumerable:-

    public interface IEnumerable

    Public method of IEnumerable:-

    IEnumerator GetEnumerator();
    

    Example of  IEnumerable:-

    Consider a list in C#:

    List<int> ages = new List<int>();
    ages.Add(10);
    ages.Add(20);
    ages.Add(30);
    ages.Add(40);
    ages.Add(50);
    

    Converting this list to IEnumerable:-

    IEnumerable<int> age_IEnumerable = (IEnumerable<int>)ages;
    foreach (int age in age_IEnumerable)
    {
        Console.WriteLine(age);
    }
