Question

I need to process more than one function that goes and performs results returning the same type of records.
I am using c# under visual studio 2010
considering the functions i have are:

class Search{
public list<wrecords> GetrecordsofAAA(string term);
public list<wrecords> GetrecordsofBBB(string term);
public list<wrecords> GetrecordsofCCC(string term);
}

and im calling the functions this way

list<wrecords> records1 = Search.GetrecordsofAAA(heart);
list<wrecords> records2 = Search.GetrecordsofBBB(heart);
list<wrecords> records3 = Search.GetrecordsofCCC(heart);

this is series processing.

I need records1, records2 and records 3 to be filled simultaneously, if possible.

Answer 1

//make a list of the search functions you want to call.
var Searches = new List<string, Func<string, IEnumerable<wrecord>>> {
    a => GetrecordsofAAA(a),
    a => GetrecordsofBBB(a),
    a => GetrecordsofCCC(a),
}

//Execute them in parallel and collect the results as lists of lists of wrecord
IEnumerable<IEnumerable<wrecord>> result = 
    Searches.AsParallel().Select(a => a(heart));
