asp.net - How to search a String in Class in c# -

I am developing an app in which I get data in a class from the net. Class is

  public class extension {public string name {get; Set; } Public listing & lt; Education & gt; Education {receives; Set; } Get public city city { Set; } Public listing & lt; Work & gt; Work {received; Set; }} Public class education {public string DegriName {get; Set; }} Public square City {public string name {get; Set; }} Public class work {public string name {get} Set; }}   
 Data is stored for any person in the above category.  
 Now I want to search for a string  q = "Which manager was graduated from USA?"   
 So I asked the above question I want to search ...  
 How many words match, I want to give the name of the user. So what are the people looking for if he  has been graduated from a manager in the United States?  (There may be fewer terms for search like  like director of India )  
 approach  manager  in  work I search for  and  graduation  for  education  and  location   USA   
 Creating an array of strings  
  string [] qList = q.Split ('');   
 And then go through the class. But I have no idea how to look for data in the classroom (efficiently).  
 And is my view enough to search or is there a better option?   
 
 
 What you are developing is a human readable and writeable query language. Start with string split, okay, start, but imagine the possibilities of search: search for people in a city or city, search for those who work for the top 500 companies or are certain In area.  
 You should develop a query language for this purpose, with a look and a look at the Parser Generator that works well with C # / .net, with simplifying grammar documents.
