Closed 2 years ago . Improve this question Is there a lint-like tool for C#? I've got the compiler to flag warnings-as-errors, and I've got Stylecop, but these only catch the most egregious errors. Are there any other must-have tools (especially for newbie C#ers like me) that point out probably-dumb things

问题 I am using iTextSharp to add page numbers to a PDF with C#. While running code analysis the MemoryStream for the output is suspected to be disposed more than once. See this warning generated by Visual Studio. Is this an API problem? Should the second parameter of PdfStamper be marked as out ? Is there a way for me to fix this warning? MemoryStream mem = null; PdfReader reader = null; PdfStamper stamper = null; try { mem = new MemoryStream(); reader = new PdfReader(m_pdf); stamper = new

问题 I'll explain the situation with an example. Suppose I have created a Roslyn Analyzer which throws Error when Class name is TestClass . Analyzer code is as below: public override void Initialize(AnalysisContext context) { context.RegisterSyntaxNodeAction(Method, SyntaxKind.ClassDeclaration); } private static void Method(SyntaxNodeAnalysisContext context) { var node = (ClassDeclarationSyntax)context.Node; var name = node.TryGetInferredMemberName(); if(name == "TestClass") { context

问题 My code is responsible for get types namespaces using Roslyn API based on solution file path; before i find out namespaces, i get the documents with: using (var ws = MSBuildWorkspace.Create()) { var solution = await ws.OpenSolutionAsync(solutionPath); //[...] some code var diagnostics = ws.Diagnostics; //[...] some code return solution.Projects.SelectMany(p => p.Documents); } When i pass as parameter some solution file path from a .NET Framework solution, the code works fine. But when i pass

问题 So this code triggers CA1031 . try { // logic } catch (FileNotFoundException) // exception type { // handle error } While this one does not: try { // logic } catch (FileNotFoundException ex) // exception var { // handle error } Because the exception type is meaningful, I don't need the ex in the first example. But it's not a a general exception type. It's not IOException or Exception . So why does it still trigger the CA1031 ? So is there a difference between catch(FileNotFoundException) and

问题 Rule CA1008 specifies that all enumerations should have a 0 value that should be named Unknown (we are not discussing flags here). I understand the reason that you want to prevent that uninitialized values would automatically get a meaning. Suppose I define the following enumeration: enum Gender { Male, Female } class Person { public string Name { get; set; } public Gender Gender { get; set; } } This specifies that each person should either be male or female (let's leave out the gender
