我试图在新表单的帮助下将MessageBox保持在顶部。

MessageBox.Show(new Form { TopMost = true }, message, heading, buttonType, icon, MessageBoxDefaultButton.Button1, Options);

当我从一个窗体调用它时，它工作正常，但是当我使用一个子弹出窗体（父用户控件的子控件）调用相同的方法时，它会抛出下面的异常。

Exception: Showing a service notification message box with an owner window is not a valid operation. Use the Show method that does not take an owner.

问题是选项参数，我试图传递下面的选项，但两者都不起作用。

MessageBoxOptions.DefaultDesktopOnly
MessageBoxOptions.ServiceNotification

child（popProductionConfirmation）方法调用：

private void callMyMethod()
{
    ShowMessageInMessageBox("Automatic Posting Done", "Production Confirmation", MessageBoxButtons.OK, MessageBoxIcon.Information, MessageBoxOptions.DefaultDesktopOnly);
}

private void ShowMessageInMessageBox(string message, string heading, MessageBoxButtons buttonType, MessageBoxIcon icon, MessageBoxOptions Options)
    {
        CommonMethods.ShowMessageInMessageBox(message, heading, buttonType, icon, Options, this);
    }

带有MessageBox的CommonMethods类：

public static void ShowMessageInMessageBox(string message, string heading, MessageBoxButtons buttonType, MessageBoxIcon icon, MessageBoxOptions Options, IWin32Window owner = null)
    {
        if (owner == null)
        {
            MessageBox.Show(new Form { TopMost = true }, message, "BTS: " + heading, buttonType, icon, MessageBoxDefaultButton.Button1, Options);
        }
        else
        {
            MessageBox.Show(owner, message, "BTS: " + heading, buttonType, icon, MessageBoxDefaultButton.Button1, Options);
        }
    }

父项和子项弹出窗口创建：

popProductionConfirmation objpopProductionConfirmation;
objpopProductionConfirmation = new popProductionConfirmation();
objpopProductionConfirmation.ShowDialog();

那么，有没有什么方法可以将MessageBox保留在顶部，或者有没有什么方法可以验证或解决这个问题呢？
