Is there is a way to search in List<Dictionary<string, object>> with a non specific string, like the LIKE OPERATION(%) in SQL and return the new List<Dictionary<string, object>>

I found this stuff, but it uses a specific string to search. Search for a value in List<Dictionary<string, object>>

For example, I have a list Dictionary like this:

List<Dictionary<string, object>> userList = new List<Dictionary<string, object>>(){
    new Dictionary<string, object>() {
        {"Id", 1},
        {"Name", "John"}
    new Dictionary<string, object>() {
        {"Id", 2},
        {"Name", "Foo"}
    new Dictionary<string, object>() {
        {"Id", 3},
        {"Name", "Admin"}
    new Dictionary<string, object>() {
        {"Id", 4},
        {"Name", "AdminAccount"}
If the user want to search a string "Jo", then he/she can get the first list with "John" name. But if the search string is "Admin", then first two last Dictionary will return.
Actually, this is achievable using loop. But I want to learn how to use LINQ to make my codes shorter.
Based on the fact you want to search the values and not the keys I think you can do this using System.Linq (add that as a using statement):
var filteredList = listOfDictionaries.Where(dictionary => dictionary.Values.Any(Value => Value.ToString().Contains(search))).ToList();
However, as your dictionary has the values as type 'object' will they always have an expected string representation?
UPDATE:
If you want to search only keys of a particular type you can do this.
var searchPair = new KeyValuePair<string, string>("Name", "searchTerm");
var filteredList = listOfDictionaries.Where(dictionary => dictionary[searchPair.Key].ToString().Contains(searchPair.Value)).ToList();
                @John You need to include using System.Linq; so that you can use the LINQ extension methods. .FindAll (as in your sample) isn't LINQ - it's a List<T> method.

                it seems to be important to use the key "Name" in the dictionary. Otherwise you might find a match in an unrelated key and falsely include the wrong dictionary

                Will it not search for entire Values of the Dictionary? Because I have many keys in the dictionary, maybe I will take much time.
