问题 I want to add an existing project to my c# solution.I used TryApplyChanges and it returns true but it doesn't save changes to real Solution. I used Microsoft.CodeAnalysis.* version 1.1.1. public void AddProject (string solutionName) { MSBuildWorkspace ws=MSBuildWorkspace.Create (); ws.OpenSolutionAsync (solutionName); ws.OpenProjectAsync ("ProjectName"); if (ws.TryApplyChanges (ws.CurrentSolution ) {// break point is here } } 回答1: There's a few problems with your code: MSBuildWorkspace doesn

问题 Trying to convert that: const string maj = "variable"; in const string MAJ = "variable"; I'm using a Diagnostic with CodeFix. I've already done the Diagnostic: var localDeclarationConst = node as LocalDeclarationStatementSyntax; if (localDeclarationConst != null && localDeclarationConst.Modifiers.Any(SyntaxKind.ConstKeyword) ) { foreach (VariableDeclaratorSyntax variable in localDeclarationConst.Declaration.Variables) { var symbol = model.GetDeclaredSymbol(variable); if (symbol != null) {

问题 I am new to Roslyn and I am trying to parse a cs file and get out the functions and properties. API Examples //won't work any more var tree = SyntaxTree.ParseText(...); var tree = SyntaxTree.ParseFle(...); var root = tree.Root; API seems to have changed and it won't work any more. Guess it works with 2012 Roslyn CTP only by the look of it. I then try the newer example: //won't work neither var compilation = CSharpCompilation.Create("HelloWorld") .AddReferences( new MetadataFileReference(

问题 I am trying to compile a simple code in C# using Microsoft.CodeAnalysis.CSharp . The problem is in trying to add the reference to mscorlib.dll . As the CreateFromAssembly method of the MetadataReference class is deprecated I am trying to use the CreateFromFile method (as suggested): var mscorlibAssembly = Assembly.Load(new AssemblyName("mscorlib.dll")).ManifestModule.Assembly; var mscorlibref = MetadataReference.CreateFromFile(mscorlibAssembly.Location); result.Add(mscorlibref); The Location

问题 I want to write a Roslyn code analyser; which needs to work out if an ObjectCreationExpression is creating an object from a local class (either in the current project or a project in the current solution); or if the class comes from somewhere else, like the Base Class Library or a Nuget package etc. How do I tell where a class comes from in Roslyn? 回答1: You can only get that with the help of the semantic model. You can get the symbol for the constructor, and the check where the type comes

问题 I'm writing a Roslyn analyzer which compares checks if const are already declared in a Localization Resx. public const string DiagnosticId = "LocalizationTool"; // You can change these strings in the Resources.resx file. If you do not want your analyzer to be localize-able, you can use regular strings for Title and MessageFormat. // See https://github.com/dotnet/roslyn/blob/master/docs/analyzers/Localizing%20Analyzers.md for more on localization private static readonly LocalizableString Title

问题 In previous version of Roslyn I could add custom data to SyntaxNode with using class derived from SyntaxAnnotation . But now SyntaxAnnotation is sealed and I can use SyntaxAnnotation only with to strings: kind and data. It is not enough for me. I want to build custom CFG from AST and make bidirectional links between CFG and AST nodes. How I can do that? 回答1: SyntaxAnnotation is sealed because your tree may be serialized, and we need to be able to serialize and deserialize the annotations. If

问题 When I compile a project (using MSBuildWorkspace.Create().OpenProjectAsync().GetCompilationAsync(); I get a Compilation back which includes x SyntaxTrees for the x files within that project. But that project also references other projects. I can see the those projects within the References property of the Compilation , but it seems that calling Compliation.GetSemanticModel does not look through these. For an arbitrary SyntaxTree that is somewhere within my project (including referenced

问题 From a Visual Studio 2015 CTP5 package, how do I get the current Roslyn workspace? I looked at How to get reference to 'Roslyn' Workspace object from IVsSolution? and Roslyn: How to get a reference to Workspace from currently loaded solution? but I still can't make it work: Workspace.CurrentWorkspace does not exist anymore I have tried importing the VisualStudioWorkspace but it is still null: public sealed class VSPackage1Package : Package { .... [Import] public VisualStudioWorkspace
