如何在ProgressBar的正中央显示进度百分比？

我尝试用Label给ProgressBar添加居中显示的文本，初始代码如下：

public partial class Form1 : Form
{
    private readonly HttpClient _httpClient;
    private readonly ProgressBar _progressBar;
    private readonly Label _labelProgress;
    private readonly Timer downloadTimer;
    private readonly Radar radar;

    public Form1()
    {
        InitializeComponent();

        _httpClient = new HttpClient();

        _progressBar = new ProgressBar
        {
            Size = lblNextTimeDownload.Size,
            Minimum = 0,
            Maximum = 100,
            Value = 0,
        };

        _labelProgress = new Label
        {
            AutoSize = false,
            TextAlign = ContentAlignment.MiddleCenter,
            Font = new Font("Arial", 12, FontStyle.Regular),
        };

        _progressBar.Controls.Add(_labelProgress);
        Controls.Add(_progressBar);
    }
}

运行后发现，_labelProgress 显示在ProgressBar的左上角，无法居中。

于是我给Label实例添加了一行代码：

Dock = DockStyle.Fill,

修改后的Label初始化代码如下：

_labelProgress = new Label
{
    AutoSize = false,
    TextAlign = ContentAlignment.MiddleCenter,
    Dock = DockStyle.Fill,
    Font = new Font("Arial", 12, FontStyle.Regular),
};

这次Label的文本确实显示在ProgressBar的正中央，但Label会完全覆盖整个ProgressBar，导致进度条的进度显示被遮挡。
