How to use System.Predicate(Of McMMSubFeature)?

WesanSyu

Hi All,

I'd like to try using the FindAll and RemoveAll methods of the McMMSubFeature collection in McMMData. Although the commad  mentions `System.Predicate(Of McMMSubFeature)`, I'm not quite sure how to actually use it in my code. Could you provide an example of writing instructions using `System.Predicate(Of McMMSubFeature)`?

Hi Wesan,

McMMData.SubFeatures is a List(Of MMSubfeature), which you can use in standard way as any List. LINQ suggested using FindAll. You can check LINQ examples of using FindAll https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.list-1.findall?view=net-10.0&utm_source=chatgpt.com

You can use McMMSubFeature.Name property to find feature by name.

You cannot use RemoveAll, as the SubFeatures is an auto-generated list. 
If you want to remove some sub-features, you can select them and then use McMMData.DeleteSelected.

Regards,

Yuri
