为了完成这项工作,您需要首先进行身份验证,以获得SID可用于访问数据的给定Google网站的有效身份.以下是您如何实现这一目标:

class Program
{
    static void Main(string[] args)
    {
        using (var client = new WebClient())
        {
            // TODO: put your real email and password in the request string
            var response = client.DownloadString("https://www.google.com/accounts/ClientLogin?accountType=GOOGLE&Email=youraccount@gmail.com&Passwd=secret&service=trendspro&source=test-test-v1");
            // The SID is the first line in the response
            var sid = response.Split('\n')[0];
            client.Headers.Add("Cookie", sid);
            byte[] csv = client.DownloadData("http://www.google.com/insights/search/overviewReport?q=test&cmpt=q&content=1&export=2");

            // TODO: do something with the downloaded csv file:
            Console.WriteLine(Encoding.UTF8.GetString(csv));
            File.WriteAllBytes("report.csv", csv);
        }
    }
}
