Answer 1

Thread app = new Thread(new ParameterizedThreadStart(ShowWindow));  
app.ApartmentState = ApartmentState.STA
在web要这样： 
protected void Button1_Click(object sender, EventArgs e) 
{  
   Thread th = new Thread(Test);
   th.SetApartmentState(ApartmentState.STA);
   th.Start();  
} 
Protected void Test()
{
}
