I agree with Paqogomez that you don't appear to have put much work into this but I also understand that it can be hard to get started. Here is some sample code that should get you on the right path.
我同意 Paqogomez 的观点，您似乎没有为此付出太多努力，但我也理解这可能很难开始。下面是一些示例代码，可以让您走上正确的道路。
private void button1_Click(object sender, EventArgs e)
{
string uriString = "http://www.google.com/search";
string keywordString = "Test Keyword";
WebClient webClient = new WebClient();
NameValueCollection nameValueCollection = new NameValueCollection();
nameValueCollection.Add("q", keywordString);
webClient.QueryString.Add(nameValueCollection);
textBox1.Text = webClient.DownloadString(uriString);
}
This code will search for "Test Keyword" on Google and return the results as a string.
此代码将在 Google 上搜索“Test Keyword”并将结果作为字符串返回。
The problems with what you are asking is Google is going to return your result as HTML that you will need to parse. I really think you need to do some research on the Google API and what is needed to programmatically request data from Google. Start your search here Google Developers.
您所问的问题是 Google 会将您的结果作为您需要解析的 HTML 返回。我真的认为您需要对 Google API 以及以编程方式从 Google 请求数据所需的内容进行一些研究。在此处开始搜索Google Developers。
Hope this helps get you started on the right path.
希望这有助于您走上正确的道路。
