C＃字典表现 [英] C# Dictionary Performance

问题描述

我正在使用Dictionary来存储数据，并将缓存它。我想避免服务器内存问题，并且通过限制字典大小或条目数量来限制字典大小，具有良好的性能。

最好的方法是什么？还有另外一个类，我应该考虑一个词典吗？

解决方案

p>

• SortedDictionary


• 列表


• HashSet

您可以查看通过查看 System.Collections.Generic 命名空间

他们是一个非常好的帖子，描述了MSDN上所有大部分收集类的优缺点。

• 选择集合类

如果您对这些类提供的内容不满意，您可以去自己的收藏类或设计一个自定义词典你的自我。

您将需要继承自己的字典fron IDictionary接口和其他类/接口，或者可以从头开始写全部。 >

以下是 Dictionary class 在MSDN

  [SerializableAttribute] 
 [ComVisibleAttribute（false） ] 
 public class Dictionary< TKey，TValue> ：IDictionary< TKey，TValue> 
 ICollection< KeyValuePair> TKey，TValue>> 
 IEnumerable< KeyValuePair< TKey，TValue>> 
 IDictionary，ICollection，IEnumerable，
 ISerializable，IDeserializationCallback 
  

I am using a Dictionary to store data, and will be caching it. I would like to avoid server memory issues, and have good performance by limiting the size of the Dictionary<>, either in size or number of entries.
What is the best method of doing this? Is there another class I should be considering other than a Dictionary?

解决方案

There are several other classes you can select from like

• SortedDictionary
• List
• HashSet

you can review the options by looking at System.Collections.Generic Namespace.

Their is a very good post, describibg pros and cons for all most of the collection classes at MSDN

• Selecting a Collection Class

If you are not satisfied by what these classes are provide, you can go for your own collection class or design a custom Dictionary your self.

you will need to inherit your custom dictionary fron IDictionary Interface and other classes / interfaces or may write all from scratch.

Here is the signature for Dictionary class at MSDN

[SerializableAttribute]
[ComVisibleAttribute(false)]
public class Dictionary<TKey, TValue> : IDictionary<TKey, TValue>, 
    ICollection<KeyValuePair<TKey, TValue>>,
    IEnumerable<KeyValuePair<TKey, TValue>>, 
    IDictionary, ICollection, IEnumerable,
    ISerializable, IDeserializationCallback
