Create batches in linq

Question

Can someone suggest a way to create batches of a certain size in linq?

Ideally I want to be able to perform operations in chunks of some configurable amount.

Answer 1

If you start with sequence defined as an IEnumerable, and you know that it can safely be enumerated multiple times (e.g. because it is an array or a list), you can just use this simple pattern to process the elements in batches:

while (sequence.Any())
{
    var batch = sequence.Take(10);
    sequence = sequence.Skip(10);

    // do whatever you need to do with each batch here
}
