新的C#Programmer - 一起添加两个numericUpDown值？

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

NumericUpDown numericUpDown1 = new NumericUpDown();
numericUpDown1.Location = new Point(10, 10);
numericUpDown1.Size = new Size(120, 20);
this.Controls.Add(numericUpDown1);

NumericUpDown numericUpDown2 = new NumericUpDown();
numericUpDown2.Location = new Point(10, 40);
numericUpDown2.Size = new Size(120, 20);
this.Controls.Add(numericUpDown2);

Label resultLabel = new Label();
resultLabel.Location = new Point(10, 70);
resultLabel.Size = new Size(120, 20);
this.Controls.Add(resultLabel);

private void UpdateResult()
{
    decimal result = numericUpDown1.Value + numericUpDown2.Value;
    resultLabel.Text = "Result: " + result.ToString();
}

numericUpDown1.ValueChanged += (sender, args) => UpdateResult();
numericUpDown2.ValueChanged += (sender, args) => UpdateResult();
