Speed up loop using multithreading in C# (Question)

Question

Imagine I have an function which goes through one million/billion strings and checks smth in them.

f.ex:

foreach (String item in ListOfStrings)
{
            


        

Answer 1

You could try the Parallel extensions (part of .NET 4.0)

These allow you to write something like:

Parallel.Foreach (ListOfStrings, (item) => 
    result.add(CalculateSmth(item));
);

Of course result.add would need to be thread safe.
