如何将字典设置为属性?举个例子
本文关键字:属性 字典 设置 | 更新日期: 2023-09-27 18:32:55
我正在尝试使用字典作为类成员。我想使用属性获取/设置字典的键/值,但我是困惑于如何将字典用作属性。由于有 2部分,我不知道如何设置获取/设置。
你可以试试这个:
class Example {
private Dictionary<int,string> _map;
public Dictionary<int,string> Map { get { return _map; } }
public Example() { _map = new Dictionary<int,string>(); }
}
实施工作将遵循以下方针:
var e = new Example();
e.Map[42] = "The Answer";
using System;
using System.Collections.Generic;
public class Program
{
public static void Main()
{
Console.WriteLine("Hello World");
var cl = new cl();
populate(cl.dict);
foreach(var d in cl.dict)
Console.WriteLine(d.Key);
}
private static void populate(Dictionary<int, string> d)
{
for (int i = 0; i < 10 ; i++)
{
if (!d.ContainsKey(i))
{
d.Add(i, i.ToString());
}
}
}
}
public class cl
{
public Dictionary<int, string> dict;
public cl()
{
dict = new Dictionary<int, string>();
}
}
你的意思是这个吗?
class MyDictionary<TKey, TValue>
{
private readonly Dictionary<TKey, TValue> _dictionary;
public void Add(TKey key, TValue value)
{
_dictionary.Add(key, value);
}
public void Clear()
{
_dictionary.Clear();
}
public bool Remve(TKey key)
{
return _dictionary.Remove(key);
}
....等方法...
public MyDictionary(Dictionary<TKey, TValue> dictionary)
{
_dictionary = dictionary;
}
}
