如何使用 yield break 中断递归 IEnumerable<T> 循环？

using System;
using System.Collections;
using System.Collections.Generic;

public class Example
{
    public static void Main()
    {
        var example = new Example();
        foreach (var item in example.RecursiveIEnumerable(0))
        {
            Console.WriteLine(item);
        }
    }

    public IEnumerable<int> RecursiveIEnumerable(int depth)
    {
        if (depth > 5)
        {
            yield break;
        }

        for (int i = 0; i< depth; i++)
        {
            yield return i;
        }

        foreach (var item in RecursiveIEnumerable(depth + 1))
        {
            yield return item;
        }
    }
}
