En del information gäller för förhandsversionen av en produkt och kan komma att ändras avsevärt innan produkten blir allmänt tillgänglig. Microsoft lämnar inga garantier, uttryckliga eller underförstådda, avseende informationen som visas här.

Tar bort profilen för det angivna användarnamnet från datakällan.

public:
 static bool DeleteProfile(System::String ^ username);

public static bool DeleteProfile(string username);

static member DeleteProfile : string -> bool

Public Shared Function DeleteProfile (username As String) As Boolean

Parametrar

username: String

Användarnamnet för den profil som ska tas bort.

Returer

Boolean

trueom användarprofilen hittades och togs bort. annars . false

Undantag

ArgumentException

username är en tom sträng ("") eller innehåller ett kommatecken.

ArgumentNullException

username är null.

Exempel

I följande kodexempel visas en ASP.NET sida som hanterar inaktiva profiler. Metoden DeleteProfile anropas när en enskild profil har valts som ska tas bort. Huruvida en profil anses vara inaktiv baseras på det datum som angetts för userInactiveSinceDate parametervärdet som skickas GetAllInactiveProfiles till metoden.

Important

Det här exemplet innehåller en textruta som accepterar användarindata, vilket är ett potentiellt säkerhetshot. Som standard kontrollerar ASP.NET webbsidor att användarindata inte innehåller skript- eller HTML-element. Mer information finns i Översikt över skriptexploateringar.

Kommentarer

Metoden DeleteProfile tar bort all profilinformation och alla egenskaper för användarprofilen för den angivna username från datakällan för den angivna ApplicationName.

Metoden DeleteProfile anropar metoden för DeleteProfiles standardprofilprovidern för att utföra borttagningsåtgärden. Standardprofilprovidern anges med defaultProvider hjälp av attributet för profilkonfigurationselementet. Om användarprofilen innehåller egenskaper som hanteras av en annan profilprovider än standardprovidern tas de inte bort. Om du vill ta bort profilegenskaper som hanteras av en annan profilprovider än standardprovidern hämtar du en referens till profilprovidern med hjälp av Providers egenskapen och anropar DeleteProfiles providerns metod direkt.
