如何用csv文件python中的内容替换文件名？

Question

我在CSV文件中包含以下内容

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Whack_a_mole
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            label1.Visible = false;
            label1.Text = "Max size is 5";

        }

        private void button1_Click(object sender, EventArgs e)
        {
            int Area = Convert.ToInt32(textBox1.Text);
            if (Area < 6)
            {
                GenerateGrid(20, 20, Area, Area, 75, 75);
            } else
            {
                label1.Visible = true;
            }

        }

        private void GenerateGrid(int gridleft, int gridtop, int horizontalCount, int verticalcount, int width, int height)
        {
            for (int i = 0; i < verticalcount; i++)
            {
                GenerateRowOfButtons(gridleft, gridtop+height*i, horizontalCount, width, height);
            }
        }

        private void GenerateRowOfButtons (int startX, int startY, int count, int width, int height)
        {
            for (int i = 0; i < count; i++)
            {
                GenerateButton(startX+i*width, startY, width, height);
            }
        }

        private void GenerateButton (int x, int y, int width, int height)
        {
            Button button = new Button();
            button.Width = width;
            button.Height = height;
            button.Left = x;
            button.Top = y;
            this.Controls.Add(button);
        }


    }
}
