    }

帮助阐明逻辑

在这段代码中

private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (wb.Document.GetElementById("login-email") != null)
            {
                wb.Document.GetElementById("login-email").InnerText = settingsForm.tEmail.Text;
                wb.Document.GetElementById("login-password").InnerText = settingsForm.tPassword.Text;
                Method_1("button luxury")[0].InvokeMember("click");
            }

               CallMethodAfterDelay(KrysomahHunting, 5000, tm);

                if (wb.Url.AbsoluteUri == "http://www.moswar.ru/metro/" && wb.ReadyState == WebBrowserReadyState.Complete)
                {
                    wb.Stop();
                    method_2("c", "Выследить Крысомаху")[0].InvokeMember("click");
                    Method_1(new string[] { "button" })[0].InvokeMember("click");
                }

        }

当程序进入方法时

method_2("c", "Выследить Крысомаху")[0].InvokeMember("click");

抛出异常ArgumentOutRangeException

我认为这可能是由

引起的

private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)

Heconstantly checks.Ifapagethatexecute方法。并且因为该方法曾经完成其工作，不再有值

因此我们得到一个异常ArgumentOutRangeException。帮助如何为这种情况制作逻辑！

Answer 1

如果您在该方法调用中添加签入该怎么办？

var method2 = method_2("c", "...");
if (method2.Count > 0)
    method2[0].InvokeMember("click");

需要有关程序逻辑的建议
