C# Yield return list, not single object [duplicate]

Question

I need batch wise sublist to process objects in batch. Parallel.ForEach is not feasible as the batch is posted to the HTTP request.

public IEnumerable<T> BatchProcess<T>(IEnumerable<T> list, int batchSize) { int page = 0; IEnumerable<T> batch; while ((batch = list.Skip(page).Take(batchSize)).Count() != 0) { page++; yield return batch; //Error CS0029 Cannot implicitly convert type 'System.Collections.Generic.List<T>' to 'T' } }

Error CS0029 Cannot implicitly convert type 'System.Collections.Generic.List' to 'T'.

Expecting "yeild return" to return a list of objects instead of returning a single object.

See "InBatches" from my personal extensions library (feel free to loot it). github.com/thesoftwarejedi/Torian.Common/blob/master/Source/… — TheSoftwareJedi

Your method signature should be

public IEnumerable<IEnumerable<T>> BatchProcess<T>(IEnumerable<T> list, int batchSize)
