界面设计如下：

实现类：

public partial class FormProgressInfo : Form
{
	public FormProgressInfo(int nMinimum = 0, int nMaximum = 100)
	{
		InitializeComponent();
		if (nMinimum >= 0 && nMaximum > nMinimum)
		{
			progressBarInfo.Maximum = nMaximum;
			progressBarInfo.Minimum = nMinimum;
			progressBarInfo.Value = nMinimum;
		}
	}

	public void SetPos(int nPos)
	{
		if (nPos <= progressBarInfo.Maximum)
		{
			progressBarInfo.Value = nPos;
			labelProgressValue.Text = $"{nPos * 100 / progressBarInfo.Maximum}%";
		}
		Application.DoEvents();
	}

	public void SetTip(string sTip = "正在执行...")
	{
		if (!string.IsNullOrEmpty(sTip))
			labelProgressTip.Text = sTip;
		Application.DoEvents();
	}

	private void FormProgressInfo_Load(object sender, EventArgs e)
	{
		if (null != Owner)
			Owner.Enabled = false;
	}

	private void FormProgressInfo_FormClosed(object sender, FormClosedEventArgs e)
	{
		if (null != Owner)
			Owner.Enabled = true;
	}
}

调用：

var formProgress = new FormProgressInfo(0, 1024);
formProgress.Show(this); //this用于指定父窗体

写进度、写提示应用SetPos、SetTip就好了。
