c# - 启动画面等待线程完成

Question

我仍然对启动画面有疑问。我不想使用属性 SC.TopMost=true。

现在我的应用场景如下:

在 progeram.cs 中:

[STAThread]
static void Main()
{
    new SplashScreen(_tempAL);// where _tempAL is an arrayList
    Application.Run(new Form1(_tempAL));
}

在 SplashScreen 类中:

public SplashScreen(ArrayList _Data)
{
    DisplaySplash()
} 
private void DisplaySplash()
{
    this.Show();
    this.TopMost = true;
    this.CenterToScreen();
    this.SetTopLevel(true);

    _allServerNarrators = new string[10];
    for (int i = 0; i < _allServerNarrators.Length; i++)
        _allServerNarrators[i] = null;

    GetFromServer();

    this.Hide();
    _serverData = new ArrayList();
    _thisData.Add(_allServerNarrators);
    _thisData.Add(_serverNarrators);

}
private void GetFromServer()
{
    _serverNarrators = new ArrayList();
    string _file = "Suras.serverNar";

    if (!Directory.Exists("c:\\ASGAQuraan"))
        Directory.CreateDirectory("c:\\ASGAQuraan");

    while (counter < 4 && _serverFiles == null)
    {
        if (Download("c:\\ASGAQuraan", _ftpServerIP, _file))
        {
            StreamReader _strReader = new StreamReader
                         ("c:\\ASGAQuraan\\"+_file,System.Text.Encoding.Default);
            string _line = _strReader.ReadLine();
            string _word;

            while (true)
            {
                while (_line != null)
                {
                    _word = _line.Substring(0, _line.IndexOf("*"));
                    int _narId = Convert.ToInt32(_word);
                    _line = _line.Substring(2);
                    int k = 0;
                    _serverNarratorNode = new ArrayList();
                    while (true)
                    {
                        int ind = _line.IndexOf("*");
                        if (ind > 0 && ind < _line.Length)
                        {
                            string str = _line.Substring(0, (ind));
                            if (k == 0)
                            {
                                _allServerNarrators[_narId] = str;
                                _serverNarratorNode.Add(str);
                            }
                            else
                            {
                                _serverNarratorNode.Add(str);
                            }
                            _line = _line.Substring(ind + 1);
                            k++;
                        }
                        else
                        {
                            _line = null;
                            break;
                        }
                    }
                    _serverNarrators.Add(_serverNarratorNode);
                    _serverFiles = "added";
                }
                _line = _strReader.ReadLine();
                if (_line == null)
                {
                    break;
                }
            }
        }
        else
            counter++;
    }
}

我想要的是闪屏类中的一些东西，它会等到线程结束。

有关详细信息，请告诉我我需要告诉您的信息。

同样的问题，同样的答案:

.NET 框架对闪屏有出色的内置支持。新建一个WF项目，Project + Add Reference，选择Microsoft.VisualBasic。添加一个新窗体，将其命名为 frmSplash。打开 Project.cs 并使其看起来像这样:

using System;
using System.Windows.Forms;
using Microsoft.VisualBasic.ApplicationServices;

namespace WindowsFormsApplication1 {
  static class Program {
    [STAThread]
    static void Main(string[] args) {
      Application.EnableVisualStyles();
      Application.SetCompatibleTextRenderingDefault(false);
      new MyApp().Run(args);
    }
  }
  class MyApp : WindowsFormsApplicationBase {
    protected override void OnCreateSplashScreen() {
      this.SplashScreen = new frmSplash();
    }
    protected override void OnCreateMainForm() {
      // Do your time consuming stuff here...
      //...
      System.Threading.Thread.Sleep(3000);
      // Then create the main form, the splash screen will close automatically
      this.MainForm = new Form1();
    }
  }
}
