未排序的哈希表

问题描述

我正在用C#编写程序我有这样的代码

i am writing a program in C#i have a code like this

Hashtable ht = new Hashtable();
            ht.Add("1", "One");
            ht.Add("2", "Two");
            ht.Add("3", "Three");
            ht.Add("4", "Four");

但是编译器对它进行排序我想知道如何防止对哈希表进行排序请帮助我

but Compiler sort iti wanna know how can i prevent sorting hashtableplease help me

推荐答案

HashTable不会进行此类排序.它会根据项目的哈希码进行重新排列，因此不会保留原始顺序.

A HashTable doesn't do sorting as such. It does rearrange the items based on their hash code, so the original order isn't preserved.

如果要保留原始顺序或要指定排序顺序，则不能仅使用HashTable.

If you want to preserve the original order, or want to specify a sort order, you can't use a HashTable only.

要指定其他排序顺序，可以使用SortedDictionary<T>.要保留原始顺序，可以将项目同时添加到Dictionary<T>和List<T>.

To specify a different sort order, you can use a SortedDictionary<T>. To preserve the original order, you can add the items both to a Dictionary<T> and a List<T>.
