Should we not change the interface here instead and do IChannelMoments?

I will move this to a separate file after merging this PR. Not yet sure where I want to put this. And maybe we could use NSubstitute instead?

I'm used to anonymous object that can implements an Interface in PHP or Kotlin 😜
I don't know NSubstitute (this one?), but I could use it instead of this Test class.

You can also check the message of the exception like we do in other places.

I can't rerun the pipeline; it seems stuck like "last time", not because of code, but for some other reasons |

You will probably need to rebase your PR? |

Description
👋
Theses method doesn't use the result of
TryGetValueand expect a non-null result:Magick.NET/src/Magick.NET/Statistics/Moments.cs
Lines 39 to 43 in d58472f
Magick.NET/src/Magick.NET/Statistics/PerceptualHash.cs
Lines 66 to 70 in d58472f
This one can - explicitly - return a null value:
Magick.NET/src/Magick.NET/Statistics/Statistics.cs
Lines 35 to 39 in d58472f
This PR:
TryGetValuefor the first too method and use index accessIf otherwise you prefer to not change the actual behavior (as it might be a breaking change, or just because the nullable returns is the wanted behavior), I will update the PR:
Regards.
