I have a list of Dictionaries something like below

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

No problem!

1 solution

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)) {
   return result;

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

It is very much near to what I need. I will let you know if I need any change. Thanks

I updated the solution with some improvements : passing the initial dictionary as a paramater, and some basic checking. Please see my updated answer.
