查询词典列表 [英] Querying a List of Dictionaries

问题描述

嗨


我有一个类似下面的字典列表

列表<字典<字符串，字符串> 

我想获取所有具有共同键值对的词典。



Ex。假设我有一个密钥作为客户。我想从列表中获取客户键值为10的所有词典。



预先感谢

解决方案

  private  List< Dictionary< string，string>> GetDictionaries（List< Dictionary< string，string>> dictionaries， string 键， string   value ）{
 List< Dictionary< string，string>> result =  new  List< Dictionary< string，string>>（）; 
  foreach （字典<字符串，字符串> dic  字典）{
 < span class =code-keyword> if （dic.ContainsKey（key）&& dic [key] .Equals（ value ））{ 
 result.Add（dic）; 
} 
} 
 返回结果; 
} 

这可以让你接近你需要的东西。

希望这有帮助。

Hi
I have a list of Dictionaries something like below

List<Dictionary<string,string>

I would like to fetch all the dictionaries which have a key value pair in common.

Ex. Assume that I have a key as Customer. I would like to fetch all the dictionaries from the list where the customer key has a value of 10.

Thanks in Advance
Gopi

解决方案

private List<Dictionary<string, string>> GetDictionaries(List<Dictionary<string, string>> dictionaries, string key, string value) {
   List<Dictionary<string, string>> result = new List<Dictionary<string, string>>();
   foreach (Dictionary<string, string> dic in dictionaries) {
      if (dic.ContainsKey(key) && dic[key].Equals(value)) {
         result.Add(dic);
      }
   }
   return result;
}

This should get you near what you need.
Hope this helps.
