[NUI] Fix a build warning CA1827 (#2314)

- Changed to use `Count()` method once for a local variable.
 Then, we do not have to be worried about CA1827.
- To fix the build warning, it could replace `Count()` method with `Any()` method
 https://docs.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca1827
- But, to improve performance as a review, use `Count()` itself.
