如何在C#中旋转标签？

using System;
using System.Windows.Forms;

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        Label label = new Label();
        label.Text = "旋转标签";
        label.Location = new Point(50, 50);
        label.Font = new Font("Arial", 12);
        label.Size = new Size(100, 25);
        this.Controls.Add(label);

        RotateLabel(label, 45);
    }
}

private void RotateLabel(Label label, float angle)
{
    label.Parent = this;
    label.BringToFront();
    label.Paint += (sender, e) =>
    {
        e.Graphics.TranslateTransform(label.Width / 2, label.Height / 2);
        e.Graphics.RotateTransform(angle);
        e.Graphics.TranslateTransform(-label.Width / 2, -label.Height / 2);
        label.TextRenderer.DrawText(e.Graphics, label.Text, label.Font, label.ClientRectangle, label.ForeColor, TextFormatFlags.HorizontalCenter | TextFormatFlags.VerticalCenter);
    };
}
