动态大小C＃字典列表 [英] Dynamic size C# Dictionary List

问题描述

我是C＃编程的新手，我需要一个帮助来创建一个Dictionary列表来存储一些字符串数据。看下面的例子



row1-> cat，dog，rat

row2-> 总线

row3-> 星期日，星期一，星期二，星期五



就像有不同列数的那样。

请告诉我如何创建字典对象和存储数据如上所述以及如何阅读它。谢谢。

推荐答案

你的意思是什么？！

Do you mean something like that?!

var myList = new Dictionary<String, List<String>>();

myList.Add("row1", new List<String>());
myList.Add("row2", new List<String>());
myList.Add("row3", new List<String>());

myList["row1"].Add("cat");
myList["row1"].Add("dog");
myList["row1"].Add("rat");		

myList["row2"].Add("bus");		

myList["row3"].Add("sunday");
myList["row3"].Add("monday");
myList["row3"].Add("tuesday");
myList["row3"].Add("friday");

Console.WriteLine("Number of rows -> " + myList.Count);

foreach(var row in myList) {
    Console.WriteLine("Number of columns in " + row.Key + " -> " + row.Value.Count);
}

[edit]fleshing out solution[/edit]

你不需要字典：只需使用 List<列表<字符串> > 。例如

You don't need a Dictionary: just use a List < List < string > >. e.g.

List<List<string>> m = new List<List<string>>();
m.Add(new List<string>());
m.Add(new List<string>());
m.Add(new List<string>());
m[0].AddRange( new string[] {"cat", "dog", "rat"});
m[1].Add("bus");
m[2].AddRange(new string[] { "sunday", "monday", "tuesday", "friday" });
foreach (var row in m)
{
  foreach (var s in row)
    Console.Write("{0} ", s);
  Console.WriteLine();
}
