我的尝试：



代码之前;

What I have tried:

Before Code;

for (int i = 0; i<10; i++)

{
    try
    {
        var newurl = url.Replace("1", $"{i}");

        var httpClient = new HttpClient();
        var html = await httpClient.GetStringAsync(newurl);

        var htmlDocument = new HtmlDocument();
        htmlDocument.LoadHtml(html);


        HtmlNode divContainer = htmlDocument.DocumentNode.SelectSingleNode("//div[@id='singlePlay']");

        HtmlNode iframe = divContainer.SelectSingleNode("//iframe");
        string path = @"C:\Users\Desktop\met.txt";

        FileStream fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);

推荐答案

{i}）;

var httpClient = new HttpClient（）;
var html = await httpClient.GetStringAsync（newurl）;

var htmlDocument = new HtmlDocument（）;
htmlDocument.LoadHtml（html）;


HtmlNode divContainer = htmlDocument.DocumentNode.SelectSingleNode（// div [@ id ='singlePlay']）;

HtmlNode iframe = divContainer.SelectSingleNode（// iframe）;
string path = @C：\ Users \Desktop\met.txt;

FileStream fs = new FileStream（path，FileMode.OpenOrCreate，FileAccess.Write）;

"{i}"); var httpClient = new HttpClient(); var html = await httpClient.GetStringAsync(newurl); var htmlDocument = new HtmlDocument(); htmlDocument.LoadHtml(html); HtmlNode divContainer = htmlDocument.DocumentNode.SelectSingleNode("//div[@id='singlePlay']"); HtmlNode iframe = divContainer.SelectSingleNode("//iframe"); string path = @"C:\Users\Desktop\met.txt"; FileStream fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);
