C# WinForm 多线程中弹出MessageBox阻塞窗口的实现方法

        public DialogResult ShowMessage(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon)
        {
            var dr = new DialogResult();
            try
            {
                var tmp = this.Invoke(new MessageBoxShow(MessageBoxShowF), new object[] { text, caption, buttons, icon });
                if (tmp != null)
                {
                    dr = (DialogResult)tmp;
                }
            }
            catch
            {

            }
            return dr;
        }
        delegate DialogResult MessageBoxShow(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon);
        DialogResult MessageBoxShowF(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon)
        {

            var dr = MessageBox.Show(text, caption, buttons, icon);
            return dr;
        }

调用方法：

ShowMessage("执行结果，是否成功?", "结果确认", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
