表单上的 c# 标签不反映文本更改

Question

OK, I am trying to help someone with a C# winform app for a dice roller. The code below is what they have done to get a basic test structure working - I suspect they don't have much experience with classes yet. Anyway the problem is that the text change for label1 is never updated on the form and I don't understand why. Any suggestions?

using System;
using System.Drawing;
using System.Windows.Forms;

namespace Dice_Roller
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();
    }
    public void DiceOne()
    {
      label1.Text = "test";
    }
    public void Form1_Load(object sender, EventArgs e)
    {
      Form1 doIt = new Form1();
      doIt.DiceOne();
      label1.Refresh();
    }
  }
}

Just use like this, it should work.

private void Form1_Load(object sender, EventArgs e)
    {
        //Form1 doIt = new Form1();
        DiceOne();  //change here
    }
