从文件读取数据和存储的最佳方法? [英] Best way to read data and store from file?

问题描述

我有一个文本文件，该文件以这种方式存储数据:

I have a text file which stores data in this manner:

Player name: NAME HERE
Speed: 7
Strength: 9
Stamina: 4
Player name: ANOTHER NAME HERE
Speed: 5
Strength: 8
Stamina: 3

同一文件包含大约15个不同的球员，我想从每个球员中收集价值，存储在一个临时的比赛变量中，然后计算速度强度和耐力的平均值，并提出一个获胜者.我的第一个想法是使用正则表达式，但我目前正在研究是否还有另一种更可持续的方式来做到这一点.

The same file contains about fifteen different players, and I want to gather values from each of them, store in a temporary race variable, then calculate the mean value of the speed strength and stamina and present a winner. My first idea was to use regular expression but I am currently investigating if there are another, more sustainable way to do this.

这是我的一个附带项目，欢迎任何帮助.谢谢

This is for a side project of mine and any help is welcome. Thanks

推荐答案

定义种族类结构:

public class Race
{
    public string Name;
    public int Speed;
    public int Strength;
    public int Stamina;
}

从文本文件中读取数据，并实例化Race对象并将其收集到List<Race>中.收集完毕后，您可以从List调用Average()以获得结果.

Read your data in from your text file, and instantiate your Race objects and collect them into a List<Race>. Once collected you can call Average() from your List to get your results.

string[] myTextFileLines = File.ReadAllLines(myTextFile);

List<Race> myRaces = new List<Race>();
for (int i = 0; i < myTextFileLines.Length; i += 4)
{
    myRaces.Add(new Race()
                    {
                        Name = myTextFileLines[i].Substring(myTextFileLines[i].IndexOf(":") + 2),
                        Speed = Convert.ToInt32(myTextFileLines[i + 1].Substring(myTextFileLines[i + 1].IndexOf(":") + 2)),
                        Strength = Convert.ToInt32(myTextFileLines[i + 2].Substring(myTextFileLines[i + 2].IndexOf(":") + 2)),
                        Stamina = Convert.ToInt32(myTextFileLines[i + 3].Substring(myTextFileLines[i + 3].IndexOf(":") + 2)),
                    });
}

Console.WriteLine("Avg Speed: {0}", myRaces.Average(r => Convert.ToDouble(r.Speed)));
Console.WriteLine("Avg Strength: {0}", myRaces.Average(r => Convert.ToDouble(r.Strength)));
Console.WriteLine("Avg Stamina: {0}", myRaces.Average(r => Convert.ToDouble(r.Strength)));
Console.ReadLine();
