C＃Linq。包含字符串列表

Question

如何檢查在哪里line.Contains（“ One”）多於一個字符串？ 例如，選擇文件如何包含帶有“名稱”列表的文本元素的行。

private void button_Click(object sender, RoutedEventArgs e)
{
  List<string> names = new List<string>() { "One", "Two", "Three" };

  try
  {
    var files = from file in Directory.EnumerateFiles(@"D:\Logs\", "*.log", SearchOption.AllDirectories)
                from line in File.ReadLines(file)
                where line.Contains("One")
                select new
                {
                  File = file,
                  Line = line
                };

    foreach (var f in files)
    {
      Debug.WriteLine("{0}\t{1}", f.File, f.Line);
    }
    //MessageBox.Show(files.Count().ToString() + " record found.");
    }
  catch (UnauthorizedAccessException UAEx)
  {
    Console.WriteLine(UAEx.Message);
  }
  catch (PathTooLongException PathEx)
  {
    Console.WriteLine(PathEx.Message);
  }
}

Answer 1

var files = from file in Directory.EnumerateFiles(@"D:\Stary komp\Logi\Logs2\", "*.log", SearchOption.AllDirectories)
            from line in File.ReadLines(file)
            where names.Any(name => line.Contains(name))
            select new
            {
              File = file,
              Line = line
            };

您可能可以嘗試使用以下方法：

line.Intersect(names).Any()

雖然，我不確定它是否可以在Linq表達式中使用？
