Question

您好我需要使用C＃废弃网页。我是使用selenium webdriver。这是在Java中工作但C＃抛出错误。这两个代码如下。

请让我知道我错在哪里

JAVA代码：---------------

            File file=new File(filePath);
            //create file here
            if(file.exists()){
            System.out.println("File already exists");
            }else{
            System.out.println("Generated File:"+filePath);
            file.createNewFile();
            FileWriter fw=new FileWriter(file);
            fw.write(parsedPage);
            fw.close();
            }
            }catch(IOException ie){
            ie.printStackTrace();
            }
            }

            }

                }

Answer 1

在C＃中

_driver.Navigate().GoToUrl(Key);
//Page Source 
var result = _driver.PageSource;

Answer 2

首先，您必须在安全设置中启用保护模式。详见this。然后，您必须将PageSource()更改为PageSource。请参阅下面的代码。

string surl = "https://www.flightradar24.com/data/aircraft/vt-ppa";
Console.WriteLine("Url to Parse====>" + surl);
driver1.Navigate().GoToUrl(surl);
string surl1 = driver1.PageSource;
driver1.Quit();
