Roslyn analyzer: Is class marked as partial

Question

Is there a way to find out whether class is partial inside Roslyn analyzer? There is a PartialImplementationPart in IMethodSymbol, but nothing similar for INamedTypeSymbol.

I'm writing a Source Generator, and I want to generate second part of the class only if it's possible (if first part is partial).

You could use the Modifier List to check if the class is partial.

var isPartial = classDeclaration.Modifiers
                                .Any(m => m.IsKind(SyntaxKind.PartialKeyword));

This does not answer the question: how to get this from an `INamedTypeSymbol`? – RdJNL May 16 '23 at 19:14

You can also look at ISymbol.Locations if you only have access to the ISymbol - more than one location is a pretty good indicator that it's a partial class.
