How do I create a linq statement to take a list of items and break them into groups of 50 each

Question

I have a list of this custom class and I'm trying to find out how to use a linq statement in C# to break that list into groups of 50 items each. Any ideas?

List<Symbol> symbolList = new List<Symbol>(); public class Symbol { public string Symbol { get; set; } public string Market { get; set; } }

Well, you can use GroupBy but 1: Unfortunatly, you should copy the result to List/Array etc 2: It looks a few difficult for understanding List<int> list = new List<int>(Enumerable.Repeat(2, 249)); int count = 0; int groupNumber = 1; var test = list.GroupBy(item => count++ < 50 ? groupNumber : groupNumber += (count = 1)).ToList(); — George Alexandria

There isn't a built in LINQ method for creating batches, however there's an awesome community maintained project called MoreLinq that contains a .Batch extension as well as all kinds of other helpful extensions.

var batched = symbolList.Batch(50); // returns IEnumerable<IEnumerable<Symbol>> // Where each collection contains 50 items
