C#哈希表进行排序由钥匙 [英] c# Hashtable sorted by Keys
本文介绍了C#哈希表进行排序由钥匙的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有在字母键和值在数字哈希表。
如何根据键哈希表进行排序?
ExchangeA,200
ExchangeV,100
ExchangeC,200
是这样
ExchangeA,200
ExchangeC,200
ExchangeV,100
解决方案
您可以使用 SortedDictionary
这将由键为你做了排序。在你的情况下, SortedDictionary<字符串,整数>
将工作:
SortedDictionary<字符串,整数>字典=新SortedDictionary<字符串,整数>();
dict.Add(「联交所C,200);
dict.Add(「联交所A,200);
dict.Add(交换V,100);
的foreach(在字典VAR KVP)
{
Console.WriteLine(键= {0},值= {1},kvp.Key,kvp.Value) ;
}
输出:
键=交换A,值= 200
键=交换C,值= 200
键=交换V,值= 100
I have a hashtable with keys in alphabetic and values in numeric. how to sort the hashtable based on keys?
ExchangeA, 200
ExchangeV, 100
ExchangeC, 200
to be like this
ExchangeA, 200
ExchangeC, 200
ExchangeV, 100
解决方案
You can use a SortedDictionary
for this which will do the sorting by key for you. In your case a SortedDictionary<string, int>
would work:
SortedDictionary<string, int> dict = new SortedDictionary<string, int>();
dict.Add("Exchange C", 200);
dict.Add("Exchange A", 200);
dict.Add("Exchange V", 100);
foreach (var kvp in dict)
{
Console.WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}
Output:
Key = Exchange A, Value = 200
Key = Exchange C, Value = 200
Key = Exchange V, Value = 100
