Question

I have a list (of objects), with one property in the object as a string.

This property always contains single words and would like to loop through all sequential combinations in pairs, for example:

• word1
• word2
• word3
• word4
• word5

I am trying to write LINQ which will allow me to iterate through the data in the following format:

• word1 [space] word2
• word2 [space] word3
• word3 [space] word4
• word4 [space] word5

Could anybody suggest the most efficient way of doing this.

I have a bunch of conditional IF statements at the moment that I’m looking to remove.

Answer 1

I think you want:

var pairs = words.Zip(words.Skip(1), (x, y) => x + " " + y);

That’s assuming you’re using .NET 4, which is when Zip was introduced.
