c＃：将网页的html源码读入字符串

Question

我希望能够使用winforms将某个网页的html源读入c＃中的字符串

我该怎么做？

Answer 1

string html = new WebClient().DownloadString("http://twitter.com");

现在使用C＃5中的async / await hotness

string html = await new WebClient().DownloadStringTaskAsync("http://github.com");

Answer 2

查看WebClient.DownloadString：

using (WebClient wc = new WebClient())
{
    string html = wc.DownloadString(address);
}

您可以使用WebClient.DownloadStringAsync或BackgroundWorker下载文件，而不会阻止用户界面。

Answer 3

var req = WebRequest.Create("http://www.dannythorpe.com");
req.BeginGetResponse(r =>
{
    var response = req.EndGetResponse(r);
    var stream = response.GetResponseStream();
    var reader = new StreamReader(stream, true);
    var str = reader.ReadToEnd();
    Console.WriteLine(str);
}, null);
