[英]Roslyn - CodeFixProvider is being fired but DiagnosticAnalyzer not for class destructor
Pseudo-code for my analyser 分析仪的伪代码
My test class: 我的测试课:
public class TestClass
{
~TestClass()
{
}
}
My diagnostic analyzer class with analyze method: 我的带有分析方法的诊断分析器类:
public class TestClassAnalyzer : DiagnosticAnalyzer
{
public const string AnalyzerId = "TestId";
...
private static void AnalyzeSymbol(SymbolAnalysisContext context)
{
var methodDeclaration = (IMethodSymbol)context.Symbol;
if (methodDeclaration.MethodKind == MethodKind.Destructor)
{
return;
}
context.ReportDiagnostic(Diagnostic.Create(...));
}
}
My code fix provider with fix method: 我的代码修复提供程序具有修复方法:
public class TestClassCodeFixProvider : CodeFixProvider
{
public sealed override ImmutableArray<string> FixableDiagnosticIds =>
ImmutableArray.Create(TestClassAnalyzer.AnalyzerId);
...
private async Task<Solution> PerformFixAsync(Document document, ...)
{
...
return await Renamer.RenameSymbolAsync(...)
}
}
If I put a breakpoint after the line with check for destructor inside my TestClassAnalyzer class, then my code never stops/breaks which makes sense to me because I jump out of the method with return keyword. 如果我在TestClassAnalyzer类中的带检查析构函数的行后放置一个断点,那么我的代码将永不停止/中断,这对我来说很有意义,因为我跳出了带有return关键字的方法。 Nevertheless, my code fix is being fired (I can put breakpoint inside the PerformFixAnync method and code stops/breaks there) and I can see red squiggly.
不过,我的代码修复程序已被触发(我可以将断点放在PerformFixAnync方法内,并在其中停止/中断代码),并且可以看到红色的波浪状。
Does anybody have any idea why the code fix is being fired although it shouldn't? 有人知道为什么不启动代码修复程序吗?
I guess your analyzer returns early for descructors as the condition is wrong: 我猜您的分析仪由于条件错误而早日返回了描述者:
if (methodDeclaration.MethodKind == MethodKind.Destructor)
{
return;
}
context.ReportDiagnostic(Diagnostic.Create(...));
negate the condition or report the condition in the then-block: 在条件块中否定条件或报告条件:
if (methodDeclaration.MethodKind != MethodKind.Destructor)
{
return;
}
context.ReportDiagnostic(Diagnostic.Create(...));
It turned out that my solution contained another class buried somewhere between folders with some old code without destructor check condition and this was causing the troubles. 事实证明,我的解决方案包含一个埋在文件夹之间某个地方的类,该类中带有一些没有析构函数检查条件的旧代码,这引起了麻烦。 This class was not event part of the source code in TFS ...
此类不是TFS中源事件的一部分...
