推荐答案

试试这个：

Try this:

FileStream fs = new FileStream(@"C:\Users\amit\Desktop\Test.txt", FileMode.Open);
StreamReader sr = new StreamReader(fs);
string str = sr.ReadToEnd();
string [] separator = {"<div class=\"info\">", "</div>"};//Store the separator in string array
string[] newStrings = str.Split(separator, StringSplitOptions.None);//Split the string using that seperator. You can again split these values using comma(,) and get the strings.

如果您使用的是ASP.NET，并且HTML文件与您的网站路径相关：

If you're using ASP.NET, and the HTML file is relative to your website path:

string html = File.ReadAllText(Server.MapPath("~/virtualPathTo/file.html"));
int start_index = html.IndexOf("<div class="info">") + 18;
int end_index = html.IndexOf("</div>") + 6;
string[] return1 = html.Substring(start_index, end_index - start_index).Split(,);

html = html.Substring(end_index);        //suppress previous div from string

... (do the same for getting the others div informations)

重复使用 System.String。 IndexOf（） [ ^ ]或一次性 System.String.IndexOfAny（） [ ^ ]您可以获得所有

By repeated use of System.String.IndexOf()[^] or a one-time System.String.IndexOfAny()[^] you can get all the

<div class="info"></div>

标签。然后，您可以从每个搜索结束

tags. From each one you can then search for the closing

并将中间内容存储在字符串数组中。



或者，由于这似乎是XML，请使用系统。 Xml.XmlDocument [ ^ ]，使用其中一种加载方法（加载（TextReader） [ ^ ]，加载（流） [ ^ ]， LoadXml（String） [ ^ ]，...）并检查其 ChildNodes [ ^ ]。

and store the in-between stuff in your string array.

Or, since this seems to be XML, use aSystem.Xml.XmlDocument[^], feed it with one of its Load methods (Load(TextReader)[^], Load(Stream)[^], LoadXml(String)[^], ...) and check its ChildNodes[^].
