Question

我需要帮助来比较文本文件中的两个按行分割的字符串值，并且还要将其计入比较的字符串中。我尝试了一些代码，但没有得到。只需比较一个值。如何传递第二个值。

所以包含方法返回布尔值，我如何计算比较值。

文本文件如下：

172.16.50.70,[17/Aug/2017:08:36:36,GET /login2.php HTTP/1.0,200,1575,-,"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36"

172.16.50.70,[17/Aug/2017:08:36:37,GET /objections/login.php HTTP/1.0,200,1988,-,"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36"

39.51.52.189,[17/Aug/2017:08:36:37,GET /objections/css/style.css HTTP/1.1,200,6198,googleusercontent.com/search?q=cache:aiou.edu.pk/objections/ssearch.php,"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.39 Safari/537.36"

代码

string Files = System.IO.File.ReadAllText(@"C:\info.txt");
string[] SplitByLine = Files.Split('\n');
foreach (var item in SplitByLine)
{
    string[] OneRowSplit = item.Split(',');
    GetIP = OneRowSplit[0];
    LapInfo = OneRowSplit.Last();
    string Filess = System.IO.File.ReadAllText(@"C:\info.txt");
    string[] SplitByLines = Filess.Split('\n');
    string ads = SplitByLines.Contains(GetIP & LapIngo).count(); // this line of code is not valid its only for telling i want some thing like this contain method take only one parameter and i also want to count comapred values
}

创建IP和浏览器组合的独特列表仅需LINQ几行即可：

string[] lines = File.ReadAllLines("somefile.txt");
IEnumerable<string> fingerPrints = lines.Select(c => $"{c.Split(",").First()} 
{c.Split(",").Last()}").Distinct();

您现在有了一个可枚举的字符串，其中每个条目都是唯一/不同的。您可以将它们写入另一个文件，或使用它们来更新原始文件。
