C# WinForm 弹出模式窗口操作滚动条

弹出的模式窗体

public partial class frmProcessBar : Form
{
    public frmProcessBar()
    {
        InitializeComponent();
    }
    
    public bool Increase(int runTime)
    {
        if (runTime > 0)
        {
            int tempTime = Convert.ToInt32(prcBar.Value);
            if (tempTime % 10 == 0)
            {
                this.labTimer.Text = (Convert.ToInt32(this.labTimer.Text) + runTime).ToString();
            }
            if (prcBar.Value + runTime < prcBar.Maximum)
            {
                prcBar.Value += runTime;
                return true;
            }else{
                prcBar.Value = prcBar.Maximum;
                this.Close();
                return false;
            }
        }
        return false;
    }
}

public delegate string AsyncMethodCaller();
public delegate void AsyncShowMethod();
private frmProcessBar myProcessBar = null;
private delegate bool IncreaseHandle(int runTime);
private IncreaseHandle myIncrease = null;

private void ShowProcessBar()
{
    myProcessBar = new frmProcessBar();
    myIncrease = new IncreaseHandle(myProcessBar.Increase);
    myProcessBar.StartPosition = FormStartPosition.CenterParent;
    myProcessBar.ShowDialog();
    myProcessBar = null;
}

string result = string.Empty;//接收返回的结果
AsyncMethodCaller callerRun = new AsyncMethodCaller(disPlay.Show); //耗时执行的方法
IAsyncResult synresult = callerRun.BeginInvoke(null, null);
this.BeginInvoke(new AsyncShowMethod(ShowProcessBar)); //启动弹出窗体
while (synresult.IsCompleted == false)
{
    this.BeginInvoke(this.myIncrease, new object[] { 1, 1 });
    Thread.Sleep(100);
}
this.BeginInvoke(this.myIncrease, new object[] { 100, 1 });
result = callerRun.EndInvoke(synresult); // 返回执行的结果
