You could avoid the 
apply
call with outputDetails. I think you should be able to cast directly to 
ImmutableArray<object>
and then pull out the inner object and cast that to a string. Shouldn't have to go through the whole JSON serialise/deserialise loop. Def something we want to make better here though.

I meant cast both so like
Copy code
(string)(
   (ImmutableArray<object>)((await networkStackRef.GetOutputDetailsAsync("eksVpcPrivateSubnetIds")).Value))
c

this chinese is means can't cast System.Collections.Immutable.ImmutableArray<object> to string
e
Oh ops missed the indexer 🤦
Copy code
(string)(
   ((ImmutableArray<object>)(
      (await networkStackRef.GetOutputDetailsAsync("eksVpcPrivateSubnetIds")).Value
   ))[0]
)

i'm new to csharp, why i can't castArray<string>, if i need the subnetIds array, how to do it?
e
oh you could, if you need the whole array
Copy code
((ImmutableArray<object>)(
      (await networkStackRef.GetOutputDetailsAsync("eksVpcPrivateSubnetIds")).Value
   )).CastArray<string>()
c
I have tried the code, but got these error
Copy code

Try 
As
instead of 
CastArray

Oh 😞 one sec let me load up visual studio.

Right ok the Cast methods on ImmutableArray are for direct array casts, not per element casts so you need to use Linq's cast method for this:
Copy code
ImmutableArray.Create(((ImmutableArray<object>)(await networkStackRef.GetOutputDetailsAsync("eksVpcPrivateSubnetIds")).Value).Cast<string>())
Make sure 
using System.Linq;
is at the top of the file.
c
Copy code
var subnetIds = ImmutableArray.Create(((ImmutableArray<object>)(await networkStackRef.GetOutputDetailsAsync("eksVpcPrivateSubnetIds")).Value).Cast<string>());
System.Console.WriteLine(subnetIds.First());

Copy code
var array = ((ImmutableArray<object>)networkingStackRef
            .GetOutputDetailsAsync("eksVpcPrivateSubnetIds").Result.Value!).Cast<string>().ToArray();
the code above is ok
I prefer rust to c#.....terrible type cast...
e
We'll probably do a Rust SDK at some point, casts are always tricky
