How to get all the indexes and filter the indexes by using Nest in C#

GetIndexAsync is removed from Assembly Nest, Version=7.0.0.0 from Version=7.0.0.0 you can use this :

 var result = await _client.Indices.GetAsync(new GetIndexRequest(Indices.All));

c# .net elasticsearch nest

This works, a slightly sexier way of writing it would be using .Except() on result.Indices.

Another route would be by using .CatIndices()

c# .net elasticsearch nest

Code Assembly Nest, Version=6.0.0.0 as below

var result = await _client.GetIndexAsync(null, c => c                                     .AllIndices()                             );

you will get result in result.Indices.Keys string list
