Code block analyzers register code block actions to analyze executable code blocks in the compilation. You can register either a stateless CodeBlockAction or a stateful CodeBlockStartAction with nested actions to analyze syntax nodes within a code block. Our analyzer registers a CodeBlockStartAction to perform stateful analysis.
context.RegisterCodeBlockStartAction<SyntaxKind>(startCodeBlockContext => { ... }
Analysis begins with a couple of early bail out checks: we are only interested in analyzing executable code within a method body and methods that have at least one parameter.
// We only care about method bodies. if (startCodeBlockContext.OwningSymbol.Kind != SymbolKind.Method) { return; } // We only care about methods ...
