C# 正则表达式输入字符串的错误格式不正确
嗨,伙计们,我有字符串 我解析它C# 正则表达式输入字符串的错误格式不正确,c#,regex,C#,Regex,嗨,伙计们,我有字符串 我解析它 string population = Regex.Match(content, @"Участники <span class=""clgry"">(?<id>[^""]+?)</span>").Groups["id"].Value; int j = 0; if (!string.IsNullOrEmpty(population)) { log("[+] Группа: " + group + "
string population = Regex.Match(content, @"Участники <span class=""clgry"">(?<id>[^""]+?)</span>").Groups["id"].Value;
int j = 0;
if (!string.IsNullOrEmpty(population))

int population_int = Convert.ToInt32(population);
if (population_int > 20000)
{
lock (accslocker)
{
StreamWriter file = new StreamWriter("opened.txt", true);
file.Write(group + ":" + population + "\r\n");
file.Close();
}
j++;
}
string population=Regex.Match(内容,@“Учаааааааааааааа107;
int j=0;
如果(!string.IsNullOrEmpty(填充))
{
日志(“[+]ГУППаПа:“+组+”Учаааааааааа1072;
int population_int=转换为32(population);
如果(人口>20000)
{
锁(accslocker)
{
StreamWriter文件=新的StreamWriter(“opened.txt”,true);
file.Write(组+”:“+population+”\r\n”);
file.Close();
}
j++;
}
}
但是当我的字符串是>时,我收到一个选项“输入字符串格式不正确”。
如何避免它?使用真正的html解析器来解析html,而不是使用正则表达式。(例如,)
string html=@“Учаааааааааааа;
HtmlAgilityPack.HtmlDocument doc=新的HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
var list=doc.DocumentNode.SelectNodes(//span[@class='lnk']/span[@class='clgry']))
.选择(x=>new
{
ParentText=x.ParentNode.FirstChild.InnerText,
Text=x.InnerText
})
.ToList();

尝试用正则表达式解析html内容不是一个好的决定。看见改用
