先看效果：

新建一个WPF窗体UMessageBox：
xaml代码：

后台代码：

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;

namespace WPF20201123.Views
{
    /// 

    /// UMessageBox.xaml 的交互逻辑
    /// 
    public partial class UMessageBox : Window
    {
        public UMessageBox()
        {
            InitializeComponent();
        }

        public new string Title
        {
            get { return this.lblTitle.Text; }
            set { this.lblTitle.Text = value; }
        }

        public string Message
        {
            get { return this.lblMsg.Text; }
            set { this.lblMsg.Text = value; }
        }

        /// 

        /// 静态方法 模拟MESSAGEBOX.Show方法
        /// 
        /// 标题
        /// 消息
        /// 
        public static bool? Show(string title, string msg)
        {
            var msgBox = new UMessageBox();
            msgBox.Title = title;
            msgBox.Message = msg;
            return msgBox.ShowDialog();
        }

        //private void Yes_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        //{
        //    this.DialogResult = true;
        //    this.Close();
        //}


        //private void No_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        //{
        //    this.DialogResult = false;
        //    this.Close();
        //}

        private void btn_Cancel_Click(object sender, RoutedEventArgs e)
        {
            this.DialogResult = false;
            //this.Close();
        }

        private void btn_OK_Click(object sender, RoutedEventArgs e)
        {
            this.DialogResult = true;
            //this.Close();
        }

        private void panel_Title_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            if (e.ButtonState == MouseButtonState.Pressed)
            {
                this.DragMove();
            }
        }

        private void btn_Close_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }
    }
}

使用方法：

UMessageBox.Show("提示：", "欢迎使用！");

或

 bool? result = UMessageBox.Show("提示：", "导出成功！是否用IDE运行？");
 if(result == true)
 {
     //其它
 }
