Troubles implementing IEnumerable

Question

I\'m trying to write my own (simple) implementation of List. This is what I did so far:

using System;
using System.Collections.Generic;
using System.Linq;
us         


        

Answer 1

Since IEnumerable<T> implements IEnumerable you need to implement this interface as well in your class which has the non-generic version of the GetEnumerator method. To avoid conflicts you could implement it explicitly:

IEnumerator IEnumerable.GetEnumerator()
{
    // call the generic version of the method
    return this.GetEnumerator();
}

public IEnumerator<T> GetEnumerator()
{
    for (int i = 0; i < Count; i++)
        yield return _array[i];
}
