Because our software is very large, so I write a simple demo. The demo can work fine. Here is my code:

private void button1_Click(object sender, EventArgs e)

{

   webBrowser1.Navigate("E:\\text.html");//webBrowser1 is just a WebBrowser control on WinForm.

   webBrowser1.Refresh();

   webBrowser1.Print();

}

But if I insert these code to my software, it will crash. So I do not know what caused  my software to crash.
