在新选项卡中打开链接时，浏览器会强制我下载它。下载后，我得到一个名为“s”的文本文件。但是我想使用 C# 访问这个 URL 并获取它的文本，不要将它作为文件保存到计算机。有没有办法做到这一点？

var webRequest = WebRequest.Create(@"http://yourUrl");
using (var response = webRequest.GetResponse())
using(var content = response.GetResponseStream())
using(var reader = new StreamReader(content)){
var strContent = reader.ReadToEnd();
}
This will place the contents of the request into strContent.
这会将请求的内容放入 strContent。
Or as adrianbanksmentioned below simply use WebClient.DownloadString()

尝试这个：
var url = "https://www.google.com.vn/s?hl=vi&gs_nf=1&tok=i-GIkt7KnVMbpwUBAkCCdA&cp=5&gs_id=n&xhr=t&q=thanh&pf=p&safe=off&output=search&sclient=psy-ab&oq=&gs_l=&pbx=1&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.&fp=be3c25b6da637b79&biw=1366&bih=362&tch=1&ech=5&psi=8_pDUNWHFsbYrQeF5IDIDg.1346632409892.1";

Since this question and my previous answer is fairly old now, a more modern answer would be to use HttpClientfrom System.Net.Http
由于这个问题和我以前的答案现在已经很老了，更现代的答案是使用HttpClientfromSystem.Net.Http
using System.Net.Http;
namespace ConsoleApp2
{
class Program
{
async static void Main(string[] args)
{
HttpClient client = new HttpClient();
string result = await client.GetStringAsync("https://example.com/test.txt");
}
}
}
If not within an async function, then:
如果不在异步函数内，则：
string result = client.GetStringAsync("https://example.com/test.txt").Result;
