通过字典对象循环 [英] Looping through dictionary object

问题描述

我很新的.NET用来在PHP中工作

I am very new to .net used to working in PHP

不过，我需要的foreach通过对象字典

However I need to foreach through a dictionary of objects

我的设置是一个MVC4应用

My setup is an MVC4 app

模型看起来像这样

public class TestModels
{
Dictionary<int, dynamic> sp = new Dictionary<int, dynamic>
{
{1, new {name="abc", age="1"}}
{2, new {name="def", age="2"}}
}

控制器

public class TestController : Controller
{
   Models.TestModels obj = new Models.TestModels();

}

我如何通过obj的对象循环和检索字典的值，并在视图中打印出来。

How do I loop through the obj object and retrieve the values of the dictionary and print them in the view.

推荐答案

一种方法是通过字典的键，我建议循环：

One way is to loop through the keys of the dictionary, which I recommend:

foreach(var key in sp.Keys)
    var value = sp[key];

另一种方式，是遍历字典作为一个序列对的：

Another way, is to loop through the dictionary as a sequence of pairs:

foreach(var pair in sp)
{
    var key = pair.Key;
    var value = pair.Value;
}

我推荐的第一种方法，因为你可以有更多的控制权，如果你装点键属性适当的LINQ语句，获取项目的顺序，例如， sp.Keys.OrderBy（X =＆GT; X）。帮助您检索键的升序排列的项目

I recommend the first approach, because you can have more control over the order of items retrieved if you decorate the Keys property with proper LINQ statements, e.g., sp.Keys.OrderBy(x => x) helps you retrieve the items in ascending order of the key.
