C# Code Analysis Using Roslyn Syntax Trivia
Where to start if we want to analyze all the comments in the code? Which syntax tree nodes do we need to traverse to do this? How can we figure out that the analyzed method contains preprocessor directives for conditional compilation? Such elements of the syntax tree as syntax trivia […]
C# Code Analysis Using Roslyn Semantic Model
Introduction In the previous notes, we analyzed the source files, relying entirely on the syntax tree and traversing its nodes. In many cases, traversing a single syntax tree is not enough to perform deep analysis. Here the concept ”semantic model’‘ comes in handy. A semantic model opens up new possibilities […]
C# Code Analysis With Roslyn’s Syntax Trees
Introduction In the previous article, we compared Visual Studio’s templates that one can use to build their own static analyzer. There we detailed how to write your first simple analyzer and talked about how Roslyn maps source code as syntax trees. Now we will talk about syntax tree structure in […]
