I want to update params of 3 levels of inner object with entityParameters: List entityParameters var filter = Builders.Filter.Eq(x => x.MachineId, id); filter &= Builders.Filter.ElemMatch(x => x.Machines, inner => inner.MachineId == id2 && inner.Machines.Any(innerInner => innerInner.MachineId == id3 && innerInner.Params.Any(ip => entityParameters.Any(ep => ep.ParamId == ip.ParamId))) update = Builders.Update.Combine(update, Builders.Update .Set(x => x.Machines.FirstMatchingElement().Machines.FirstMatchingElement().Params, entityParameters));
问题回答
I can t do it with nested FirstMatchingElement() I needed to use a dynamic mongo string without types.
