我有一个像这样的文本文件：

IPen ID Datetime                                    Status
48      Tuesday, September 27, 2016 14:17:23        OK
48      Tuesday, September 27, 2016 14:17:26        NG
48      Tuesday, September 27, 2016 14:17:30        OK
48      Tuesday, September 27, 2016 14:17:47        NG
48      Tuesday, September 27, 2016 14:17:50        OK
48      Tuesday, September 27, 2016 14:17:53        OK
48      Tuesday, September 27, 2016 14:17:57        OK
48      Tuesday, September 27, 2016 14:18:00        OK
48      Tuesday, September 27, 2016 14:18:03        OK
48      Tuesday, September 27, 2016 14:18:06        NG
48      Tuesday, September 27, 2016 14:18:10        OK
48      Tuesday, September 27, 2016 14:18:13        NG
48      Tuesday, September 27, 2016 14:18:17        NG

我想看看有多少status是OK多少status的NG。是否有可能结合lines.count并lines.contains在一起，或任何其它方式？感谢您的帮助和回复。

这是您的操作方式。您唯一需要关心的是文件格式如何真正稳定。如果确定OK和NG始终是大写且在行的末尾，则可以这样做。否则，您应该找到一组稳定的条件。

class Program
{
    static void Main(string[] args)
    {
        var filePath = @"c:\temp\file.txt";
        var lines = File.ReadAllLines(filePath);
        var oks = lines.Count(s => s.EndsWith("OK"));
        var ngs = lines.Count(s => s.EndsWith("NG"));
        Console.WriteLine("OKs: {0}, NGs {1}",oks,ngs);
    }
}
