splashform 显示 主窗体 正解

下面是部分代码：
 
AppStart 类，包含Main方法
 
public class AppStart
 
{
 
    public AppStart()
 
    {
 
    }
 
    [STAThread]
 
    static void Main(string[] args)
 
    {
 
        //    显示Splash窗体
 
        Splash.Show();
 
        DoStartup(args);
 
        //    关闭Splash窗体
 
        Splash.Close();
 
    }
 
    static void DoStartup(string[] args)
 
    {
 
        //    做需要的事情
 
        frmMain f = new frmMain();
 
        Application.Run(f);
 
    }
 
}
 
Splash功能类：
 
public class Splash
 
{
 
    static frmSplash MySplashForm = null;
 
    static Thread MySplashThread = null;
 
    static void ShowThread() 
 
    {
 
        MySplashForm = new frmSplash();
 
        Application.Run(MySplashForm);
 
    }
 
    static public void Show() 
 
    {
 
        if (MySplashThread != null)
 
            return;
 
        MySplashThread = new Thread(new ThreadStart(Splash.ShowThread));
 
        MySplashThread.IsBackground = true;
 
        MySplashThread.ApartmentState = ApartmentState.STA;
 
        MySplashThread.Start();
 
    }
 
    static public void Close() 
 
    {
 
        if (MySplashThread == null) return;
 
        if (MySplashForm == null) return;
 
        try 
 
        {
 
            MySplashForm.Invoke(new MethodInvoker(MySplashForm.Close));
 
        }
 
        catch (Exception) 
 
        {
 
        }
 
        MySplashThread = null;
 
        MySplashForm = null;
 
    }
 
    static public string Status 
 
    {
 
        set 
 
        {
 
            if (MySplashForm == null) 
 
            {
 
                return;
 
            }
 
            MySplashForm.StatusInfo = value;
 
        }
 
        get 
 
        {
 
            if (MySplashForm == null) 
 
            {
 
                throw new InvalidOperationException("Splash Form not on screen");
 
            }
 
            return MySplashForm.StatusInfo;
 
        }
 
    }
 
}
