C＃从日志文件读取特定属性

Question

在我的MUGEN锦标赛程序中，我想处理游戏创建的日志文件中的比赛结果。 日志如下所示：

[Match 1]
totalmatches = 1
team1.1 = 
team2.1 = 
stage = stages/kowloon.def

[Match 1 Round 1]
winningteam = 1
timeleft = -1.00
p1.name = Knuckles the Echidna
p1.life = 269
p1.power = 0
p2.name = Shadow the Hedgehog
p2.life = 0
p2.power = 2684

[Match 1 Round 2]
winningteam = 2
timeleft = -1.00
p1.name = Knuckles the Echidna
p1.life = 0
p1.power = 1510
p2.name = Shadow the Hedgehog
p2.life = 586
p2.power = 2967

[Match 1 Round 3]
winningteam = 2
timeleft = -1.00
p1.name = Knuckles the Echidna
p1.life = 0
p1.power = 3000
p2.name = Shadow the Hedgehog
p2.life = 789
p2.power = 777

我想要的是处理最后的winningteam属性，以确定比赛的结果。 最有效的方法是什么？ （也许使用LINQ）

Answer 1

您可以使用File.ReadLines返回作为IEnumerable<string>的行的枚举。

// string path contains file path and file name.
string line = File.ReadLines(path)
    .LastOrDefault(ln => ln.StartsWith("winningteam ="));

现在在=处分割字符串，修剪第二部分，然后将团队编号作为字符串

if (line != null) {
    string team = line.Split('=')[1].Trim();
    // With "winningteam = 2", [0] = "winningteam ", [1] = " 2"

    // Optionally convert it to a number
    int teamNo = Int32.Parse(team);

    ...
}
