I have this error in unity 2019.2.13f1?

Question

Unity

I wrote a script, and when I want to run a coroutine, here is an error, (right after saving the robots appear)
Assets\Scripts\LuckyGame.cs(34,17): error CS0542: 'LuckyGame': member names cannot be the same as their enclosing type
Here is the script, please help if you can

using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
using UnityEngine;
using System;
using UnityEngine.Monetization;
using UnityEngine.SceneManagement;

public class LuckyGame : MonoBehaviour
{
    public int price;

    public Text priceText;


   public void StartGame()
   {
        if(Main.money > 4)
        {
            StartCoroutine(LuckyGame());
        }
    }

    void Update()
    {
        priceText.text = price + "";
    }

    IEnumerator LuckyGame()
    {
        price = Random.Range(0, 11);
        Main.money += price;
        yield return new WaitForSeconds(0.5f);
        price = 0;
    }

 
}

Answer 1

at least google translate would translate the error message.
nothing confuses in these two lines?
IEnumerator LuckyGame()
public class LuckyGame : MonoBehaviour
and a class and method with the same name and in the error 'LuckyGame' is mentioned.
then try to guess how to fix it yourself))) it would be great.
