Question

I’m new to Lambda expressions so have been experimenting from an hour.

I have a generic list – List<KeyValuePair<int, string>> basically holding a key

and a value pair. I’m looking to print the list items using lambda expressions. Can anyone

help me in translating the following foreach statement using Lambda expressions ?

foreach(KeyValuePair<int, string> kvp in list)
{
    Console.WriteLine(kvp.Key.ToString() + " ----> " + kvp.Value.ToString());
}

Glad i was able to figure this out by myself 🙂

list.ForEach(item => Console.WriteLine(item.Key.ToString()  + " ----> " + item.Value.ToString()));

list: is the name of the list you want to traverse through

list<string> names=new list<string>{"name1","name2","name3"}; 
names.ForEach(name=>Console.WriteLine(name)); // write names to the console
console.Readline(); // wait on console until input
