Opties voor regels in codestijl

  • Artikel

U kunt consistente codestijl definiëren en onderhouden in uw codebasis door .NET-codestijlregels en de bijbehorende opties in een configuratiebestand te definiëren. Deze regels worden weergegeven door verschillende ontwikkelings-ID's, zoals Visual Studio, terwijl u uw code bewerkt. Voor .NET-projecten kunnen deze regels ook worden afgedwongen tijdens het bouwen. U kunt afzonderlijke regels in- of uitschakelen en de mate configureren waarop u elke regel wilt afdwingen, via een ernstniveau.

Tip

  • Wanneer u opties voor codestijlen definieert in een EditorConfig-bestand, configureert u hoe u de codestijlanalyses wilt analyseren. Het EditorConfig-bestand is het configuratiebestand voor deze analysen.
  • Opties voor codestijlen kunnen ook worden ingesteld in Visual Studio in het dialoogvenster Opties voor teksteditor . Dit zijn opties per gebruiker die alleen worden gerespecteerd tijdens het bewerken in Visual Studio. Deze opties worden niet gerespecteerd tijdens het bouwen of door andere IDE's. Als het project of de oplossing die in Visual Studio is geopend, bovendien een EditorConfig-bestand heeft, hebben opties uit het EditorConfig-bestand voorrang. In Visual Studio in Windows kunt u ook een EditorConfig-bestand genereren op basis van de opties voor teksteditor. Selecteer Extra Opties>>Teksteditor> [C# of Basis] >Codestijl>Algemeen en klik vervolgens op .editorconfig-bestand genereren vanuit instellingen. Zie Voorkeuren voor codestijlen voor meer informatie.

Regels voor codestijlen zijn onderverdeeld in de volgende subcategorieën:

Elk van deze subcategorieën definieert een eigen syntaxis voor het opgeven van opties. Zie de naslaginformatie over regels in codestijl voor meer informatie over deze regels en de bijbehorende opties.

Voorbeeld van EditorConfig-bestand

Hier volgt een voorbeeld van een .editorconfig-bestand met de standaardopties om aan de slag te gaan.

Notitie

Als u .NET 8 of een eerdere versie gebruikt, wordt de syntaxis die wordt gebruikt om de ernst in dit voorbeeldbestand op te geven mogelijk niet in acht genomen tijdens de build. In dat geval kunt u de ernst instellen met behulp van de configuratiesyntaxis voor ernst op basis van regel-id's voor analysen. Zie Optieindeling voor meer informatie.

Tip

  • In Visual Studio kunt u het volgende standaard .NET .editorconfig-bestand toevoegen aan uw project vanuit het dialoogvenster Nieuw item toevoegen. Zie EditorConfig-bestanden toevoegen en verwijderen voor gedetailleerde stappen.
  • Voor Visual Studio Code kunt u de invoegtoepassing EditorConfig voor VS Code gebruiken om de gebruikers-/werkruimte-instellingen te overschrijven met instellingen in .editorconfig-bestanden.
