Identify if class is abstract with Roslyn

问题

I've searched here I didn't find the answer here.

How can I know if class is a abstract class from a ClassDeclarationSyntax.

Here is my code:

public override void VisitClassDeclaration(ClassDeclarationSyntax node)
{
    var className = node.Identifier.Text;
    var namespaceName = (node.Parent as NamespaceDeclarationSyntax)?.Name.ToString();
    var isAbastract = ??????
}

    var isAbstract = node.Modifiers.Any(x => x.IsKind(SyntaxKind.AbstractKeyword));
}
