在启动画面标签 c# 上显示数据处理

Question

屏幕已经完成我使用的是Devexpress SplashScreen。它在开始时打开并在加载所有数据时关闭，直到主应用程序打开。现在我的问题是如何将后台加载的数据放入标签中，以便用户看到正在发生的事情。

查看 SplashScreenManager.SendCommand 以了解应用程序与初始屏幕之间的通信

表单代码

        private void btnShowSplashScreen_Click(object sender, EventArgs e) {
            // Open a Splash Screen
            SplashScreenManager.ShowForm(this, typeof(SplashScreen1), true, true, false);

            // The splash screen will be opened in a separate thread. To interact with it, use the SendCommand method.
            for (int i = 1; i <= 100; i++) {
                SplashScreenManager.Default.SendCommand(SplashScreen1.SplashScreenCommand.SetProgress, i);
                //To process commands, override the SplashScreen.ProcessCommand method.
                Thread.Sleep(25);
            }

            // Close the Splash Screen.
            SplashScreenManager.CloseForm(false);
        }

启动代码

        public override void ProcessCommand(Enum cmd, object arg) {
            base.ProcessCommand(cmd, arg);
            SplashScreenCommand command = (SplashScreenCommand)cmd;
            if (command == SplashScreenCommand.SetProgress) {
                int pos = (int)arg;
                progressBarControl1.Position = pos;
            }
        }


        public enum SplashScreenCommand {
            SetProgress,
            Command2,
            Command3
        }
