有关如何实现从文本文件读取定值的示例代码 [英] Sample code on how to implement definite value reading from text files
问题描述
您好，先生，
美好的一天！
我想在C#控制台应用程序中索取示例代码，以了解如何实现以下方案.
示例场景:
(输入来自文本文件)(也在文本文件中输出)
我有三种动物(CAT，DOG，MOUSE)，用户需要在猫，狗和鼠标上用几个数字(未知数字)命名，并且它们在特定的颜色(例如黑色，白色，棕色)之间也有所区别.并根据它们的名称和颜色计算特定动物的数量. (例如，狗类，名称:LASSIE，颜色:BLACK，WHITE和BROWN，获取计数:找到5个名称为LASSIE的黑狗，发现3个名称为LASSIE的白狗，发现2个名称为LASSIE的棕狗)
表格示例:
-----------------------------------------
动物名称为黑白色棕
-----------------------------------------
猫加菲猫2 1 5
CAT BELLA 1 4 3
CAT KITTA 7 9 6
狗拉西5 3 2
狗滑雪者2 1 4
MOUSE MOUSSY 1 3 5
鼠鼠3 6 9
鼠标力量6 2 2
MOUSE JIMM 1 0 1
-----------------------------------------
总计:28 26 37
唯一的固定变量是猫狗和老鼠，颜色为黑白色棕色，
确定值的未知数中有名称，用户可以指定不同的名称和数字.
先生，请在这方面需要您的帮助.
提前谢谢！
这是我的示例代码
Hi Sir,
Good day!
I wanted to ask for a sample code in C# console application, on how could I implement the following scenario.
Sample Scene:
(input came from a text file) (output in a text file also)
I have three animals (CAT, DOG, MOUSE), the user needs to give a name on cat, dog and mouse in a several numbers (unknown numbers), plus they are differentiated on particular colors like BLACK, WHITE, BROWN. And count the number of particular animals based on their names and colors. (eg. class DOG, name: LASSIE, color: BLACK, WHITE and BROWN, Get Count: 5 Black Dogs found with a name of LASSIE, 3 White dogs found with a name of LASSIE, 2 Brown dogs found with a name of LASSIE)
Table example:
-----------------------------------------
ANIMALS NAMES BLACK WHITE BROWN
-----------------------------------------
CAT GARFIELD 2 1 5
CAT BELLA 1 4 3
CAT KITTA 7 9 6
DOG LASSIE 5 3 2
DOG SKITTER 2 1 4
MOUSE MOUSSY 1 3 5
MOUSE RATTY 3 6 9
MOUSE MIGHTY 6 2 2
MOUSE JIMM 1 0 1
-----------------------------------------
TOTAL: 28 26 37
The only fix variables are cat dog and mouse, and the color black white brown,
the unknown of definite value there are the names, the user can give different names and numbers.
Please Sir, I need your help on this.
Thanks in advance!

推荐答案
考虑使用字典存储从文件中解析出的数据，类似这样的方法可能会为您解决:
Consider using dictionaries to store the data parsed from the file, something like this might solve it for you:
using System;
using System.Collections.Generic;
using System.IO;
namespace SocketSample
{
class Program
{
private static void ParseLine(string line, IDictionary<string, IDictionary<string, IDictionary<string, int>>> animals)
{
if (line.Trim() == String.Empty)
return;
try
{
string[] parts = line.Split(' ');
string animal = parts[0];
string name = parts[1];
int blacks = Convert.ToInt32(parts[2]);
int whites = Convert.ToInt32(parts[3]);
int browns = Convert.ToInt32(parts[4]);
if (!animals.ContainsKey(animal))
animals[animal] = new Dictionary<string, IDictionary<string, int>>();
if (!animals[animal].ContainsKey(name))
{
animals[animal][name] = new Dictionary<string, int>();
animals[animal][name]["Black"] = 0;
animals[animal][name]["White"] = 0;
animals[animal][name]["Brown"] = 0;
}
animals[animal][name]["Black"] += blacks;
animals[animal][name]["White"] += whites;
animals[animal][name]["Brown"] += browns;
}
catch (Exception e)
{
Console.Error.WriteLine("Failed to parse line \"{0}\", {1}", line, e.Message);
}
}
private static void Dump(IDictionary<string, IDictionary<string, IDictionary<string, int>>> animals)
{
foreach(string animal in animals.Keys)
{
foreach(string name in animals[animal].Keys)
{
foreach(string color in animals[animal][name].Keys)
{
Console.WriteLine("There are {0} {1} {2} named {3}", animals[animal][name][color], color, animal, name);
}
}
}
}
public static void Main(string[] args)
{
IDictionary<string, IDictionary<string, IDictionary<string, int>>> animals = new Dictionary<string, IDictionary<string, IDictionary<string, int>>>();
foreach (string line in File.ReadAllLines(@"your_input_file_here.txt"))
{
ParseLine(line, animals);
}
Dump(animals);
}
}
}
请注意，这仅是示例，正确的解决方案将验证绑定的事物(例如动物类型).
希望这会有所帮助，
弗雷德里克(Fredrik)
Note that this is just an example and a proper solution would verify things that are bound (such as animal types).
Hope this helps,
Fredrik
