Sorting a List in C# using List.Sort(Comparison<T> comparison

Question

I have created a class as follows:

public class StringMatch
{
   public int line_num;
   public int num_of_words;
}

I have created a list

List<StringMatch> sm;

it has few elements in it.

How do I sort this list using the Comparison<T> comparison overload? The sorting must be done based on the num_of_words field.

Answer 1

You can write lambda expression comparing two objects like this:

sm.Sort((x,y)=>x.num_of_words.CompareTo(y.num_of_words));

you can inverse sorting adding -

sm.Sort((x,y)=>-x.num_of_words.CompareTo(y.num_of_words));
