如何从特定网页复制所有文本并将其保存到记事本C#

Question

我有一个C#Windows窗体应用程序,它根据某些条件启动网页.

现在我希望我的应用程序自动复制该页面中的所有文本(CSV格式)并粘贴并保存在记事本中.

以下是需要复制的数据示例的链接:http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html? req_city = Johannesburg& req_state=& req_statename= South+非洲和格式= 1

任何帮助将不胜感激.

Answer 1

您可以使用.NET 4.5中的新玩具HttpClient,例如如何获取谷歌页面:

 var httpClient = new HttpClient();
 File.WriteAllText("C:\\google.txt",    
                           httpClient.GetStringAsync("http://www.google.com")
                                     .Result);  

Answer 2

http://msdn.microsoft.com/en-us/library/fhd1f0sw.aspx与http://www.dotnetspider.com/resources/21720-Writing-string-content-file.aspx相结合

public static void DownloadString ()
{
    WebClient client = new WebClient();
    string reply = client.DownloadString("http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html?req_city=Johannesburg&req_state=&req_statename=South+Africa&format=1");

    StringBuilder stringData = new StringBuilder();
    stringData = reply;  
    FileStream fs = new FileStream(@"C:\Temp\tmp.txt", FileMode.Create);
    byte[] buffer = new byte[stringData.Length];
    for (int i = 0; i < stringData.Length; i++)
    {
        buffer[i] = (byte)stringData[i];
    }
    fs.Write(buffer, 0, buffer.Length);
    fs.Close();
}

Edit Adil 使用的WriteAllText方法，效果更好。所以你会得到这样的东西：

WebClient client = new WebClient();
string reply = client.DownloadString("http://www.wunderground.com/history/airport/FAJS/2012/10/28/DailyHistory.html?req_city=Johannesburg&req_state=&req_statename=South+Africa&format=1");
System.IO.File.WriteAllText (@"C:\Temp\tmp.txt", reply);
