C#如何计算textfile的特定部分的总和？

Question

我有这样的文本文件:

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.

这是你如何做到的.您唯一应该关心的是文件格式是如何稳定的.如果你确定OK和NG总是大写并且在行尾,你可以这样做.否则,你应该找到一套稳定的条件.

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);
    }
}
