code-analysis

问题 I want to create extra rules in FXCop. Custom Rules to help ensure specific best practices like checking against inline sql. I'm really looking for good resources and examples. Thanks! 回答1: This tutorial seems really comprehensive. 回答2: The tutorial above is pretty good. I knocked together a sample VS project that also might be useful, since I couldn't find any example projects http://www.doogal.co.uk/files/FxCopRules.zip 回答3: You can also use the commercial tool NDepend to write your custom

问题 The code looks like below: namespace Test { public interface IMyClass { List<IMyClass> GetList(); } public class MyClass : IMyClass { public List<IMyClass> GetList() { return new List<IMyClass>(); } } } When I Run Code Analysis i get the following recommendation. Warning 3 CA1002 : Microsoft.Design : Change 'List' in 'IMyClass.GetList()' to use Collection, ReadOnlyCollection or KeyedCollection How should I fix this and what is good practice here? 回答1: To answer the "why" part of the question

问题 It seems that Visual Studio 2015 saves the GlobalSuppression.cs file using a UTF-16 encoding. This is annoying when using SVN as it perceives that a UTF-16 file is a binary file. Questions: Using Visual Studio, is it possible to save GlobalSuppression.cs with a UTF-8 encoding? Alternatively, can someone provide a location where I can find the template that this file is based on (if one exists)? Note that I can't find a template in Common7\IDE\ItemTemplates . 回答1: To change the encoding of the

问题 I have a fluent, extensible validation helper like: Assert.That(aParameter).IsNotNull(); It is extensible because the That method is actually generic (That<T>) and uses implicit typing to return a generic IAssertCondition<T> object. IsNotNull is actually an extension method. Anyway, the problem using this approach to validate the parameters passed into a method is that I get CA1062 warnings instructing me to validate the arguments before using them which, of course, I am already doing. I read

问题 Because of these two KB articles, I am confused: CA1704: Identifiers should be spelled correctly CA1709: Identifiers should be cased correctly I have a property named ICD9 . My code analysis says that I have to change it to Icd That sounds reasonable to me. I go and change it to Icd9 (I am not sure why it's suggesting Icd not Icd9 ) and I get a different warning The KB says if my acronym is three-letter long I should use Pascal casing. Isn't Icd9 Pascal cased? I feel that 9 has causing the

问题 What would the running time be? I got O(n^2) `cin >> n; min = 2*n; max = (n+3)*10; for(int i=0; i<1000; i++) for(int j =0; j<n; j++) for(int k = min; k< max;k++) p = f+c+m ` 回答1: No matter what outer loop runs 1000 times..so the complexity ~ O(n^2) . [innermost runs 10n+30-2n = 8n+30 times and loop with variable j runs n times..] 回答2: The number of times p is computed is: 1000 * n * (max - min) = 1000 * n * ((n + 3)*10 - 2*n) = 1000 * n * (10*n + 30 - 2*n) = 1000 * n * (8*n + 30) = 8000 * n^2

问题 How does one calculate the time complexity with conditional statements that may or may not lead to higher oder results? For example: for(int i = 0; i < n; i++){ //an elementary operation for(int j = 0; j < n; j++){ //another elementary operation if (i == j){ for(int k = 0; k < n; k++){ //yet another elementary operation } } else { //elementary operation } } } And what if the contents in the if-else condition were reversed? 回答1: Your code takes O(n^2). First two loops take O(n^2) operations.

问题 I'm trying to run code analysis for the first time on my native C++ application. I'm developing using Visual Studio 2013 Ultimate and compiling using the Visual C++ Compiler Nov 2013 CTP (CTP_Nov2013), which is the latest (I believe) compiler from MS for C++11. When trying to run Code Analysis I receive the following warning: warning D9040: ignoring option '/analyze'; Code Analysis warnings are not available in this edition of the compiler So I'm wondering if it's because I'm using this new

问题 I have a (.NET 4) test project which references (the .NET 4) NSubstitute.dll. When I run CodeAnalysis against the project I get a number of CA0001 errors: Running Code Analysis... MSBUILD : error : CA0001 : The following error was encountered while reading module 'NSubstitute': Could not resolve type reference: [mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]System.Runtime.CompilerServices.ExtensionAttribute.

问题 Given the following class heirarchy: class Base { protected virtual void Do(int value) { } } class Derived1 : Base { sealed protected override void Do(int value) { base.Do(value); } } class Derived2 : Derived1 { public Derived2() { Do(999); } } ... the code analysis warning CA2214 is resolved by simply adding the sealed keyword to Derived1.Do() . So far, so good. Now let's make Do() generic: class Base { protected virtual void Do<T>(T value) { } } class Derived1 : Base { sealed protected
