检索字典 <string, int> 使用DictionarySectionHandler从app.config中获取

Question

I am trying to store a Dictionary in app.config. It would be very useful to avoid having to parse each string by while using NameValueCollectionSectionHandler, so I was looking instead at DictionarySectionHandler.

I have been able to import a Hashtable, but it seems I can only get string values. Is there a way to get to a Dictionary directly without parsing everything?

Is there anyway to import a Dictionary directly? I cannot seem to get DictionarySectionHandler to give me an actual Dictionary.

Answer 1

DictionarySectionHandler will always return an HashTable

You just have to transform it to a Dictionary using the types that you want

For examples if your Dictionary values are integer you could do

Dictionary<string,int> targetDictionary = sourceHashtable.Cast<DictionaryEntry>().ToDictionary(d => (string)d.Key, d => (int)d.Value);
