在应用程序启动时更新启动画面标签以告知用户发生了什么的最佳方法是什么?问题是闪屏是在覆盖方法中创建的,而更新必须在静态主方法中完成,它无法访问“this.SplashScreen”。
class SingleInstanceApplication : WindowsFormsApplicationBase
{
[STAThread]
static void Main(string[] args)
{
SetSplashInfo("Data configuration", "Applying DataDirectory");
//Can't be done, this method is static**
//Do some stuff, code removed for reading purposes
}
protected override void OnCreateSplashScreen()
{
this.SplashScreen = new TestSplash();
this.SplashScreen.TopMost = true;
base.OnCreateSplashScreen();
}
private void SetSplashInfo(string txt1, string txt2)
{
if ( this.SplashScreen == null)
return;
TestSplash splashFrm = (TestSplash)this.SplashScreen;
splashFrm.label1.Text = txt1;
splashFrm.label2.Text = txt2;
}
}
