问题 In Anders Hejlsberg's .NET 4.0 presentation he discussed in NET 5.0 ("or some future release") they are working on a "Compiler as a Service" model. Anders Hejlsberg's states: [source][1] "We want to open up our compiler so it becomes an API you can call to compile a piece of code and get back expression trees and/or IL. This enables a whole host of scenarios, such as application programmability, an interactive prompt, user-written refactorings, and domain specific languages that have little

问题 I want to write a custom code analyzer in Visual Studio 2015 for a C# ConsoleApplication. For this reason I don't want to create a seperate "Analyzer with Code Fix" project from template, because this requires to add this analyzer in my projects as nuget package. Is it possible, to add a analyzer reference manually? I would like to reference the analyzer without nuget. 回答1: If you add an analyzer as Nuget and check the content of your project, you'll see that only an <Analyzer Include="..." /

问题 I have an application in which I use the Roslyn scripting engine (namespace Microsoft.CodeAnalysis.Scripting ). What I have right now is this: public static async Task<object> Execute(string code, CommandEventArgs e) { if (_scriptState == null) { var options = ScriptOptions.Default; options .AddReferences(typeof (Type).Assembly, typeof (Console).Assembly, typeof (IEnumerable<>).Assembly, typeof (IQueryable).Assembly) .AddImports("System", "System.Numerics", "System.Text", "System.Linq",

问题 Is there a way to read the default namespace setting from the IProject interface or any other Roslyn interface? I know that I can parse the project's file but I think this should be possible using Roslyn API but I cannot find how to do that. Thanks in advance for information. 回答1: Unfortunately, Roslyn does not expose a way to do that at the moment, but I agree that it is something we will probably need eventually. 回答2: The library Microsoft.Build.Evaluation, which is, I believe, the

问题 When I try to annotate class, property and method, and then try to retrieve annotated node, only the class one is returned. Why? Here is the code that annotates SyntaxAnnotation propertyAnnotation = null; SyntaxAnnotation classAnnotation = null; SyntaxAnnotation setMethodAnnotation = null; document = document .AnnotateClass(classDeclaration, out classAnnotation) .AnnotateProperty(propertyDeclaration, out propertyAnnotation) .AnnotateSetMethod(setMethodDeclaration, out setMethodAnnotation); I

问题 I'm using Roslyn's CSharpSyntaxRewriter to rewrite the following: string myString = "Hello "; myString += "World!"; to: string myString = "Hello "; myString += "World!"; Log("myString", myString); My syntax rewriter overrides VisitAssignmentExpression as follows. public override SyntaxNode VisitAssignmentExpression(AssignmentExpressionSyntax node) { //Construct a new node without trailing trivia var newNode = node.WithoutTrailingTrivia(); InvocationExpressionSyntax invocation = //Build proper

问题 How do I get the symbol info of the instance in a CatchDeclaration? Basically I want to get the symbol so that I can compare it later to see that a method was called on that symbol. Basically I have this: catch (Exception ex) {} and I want the SymbolInfo for "ex". I get the catch declaration with: var catchDeclaration = catchClause.DescendantNodes().OfType<CatchDeclarationSyntax>().FirstOrDefault(); But I seem to only be able to get the SyntaxToken from the declaration ( catchDeclaration

问题 I'm creating a script editor for my application, and I'd like to have it be able to run both C# and VB.NET scripts using Roslyn. I got this working with C# by using the CSharpScript class in the Microsoft.CodeAnalysis.CSharp.Scripting assembly/namespace, however there is no equivalent VisualBasicScript class that I can find, nor a Microsoft.CodeAnalysis.VisualBasic.Scripting assembly. I've scoured the web and can find nothing useful about running VB.NET scripts, and all the samples on the

问题 I'm confused which method to use on the AnalysisContext context object to have every function/method's local variables anazlyed: either RegisterSymbolAction() or RegisterSyntaxNodeAction() . It's likely RegisterSymbolAction() as per the sample Diagnostic with Code Fix (NuGet + VSIX) in the Roslyn SDK Project Templates.vsix. I'm debugging using a simple console app whose Main() has a handful of local variables of type string and int . I've tried these two, but neither will trigger any variable
