Exempel

I följande exempel används Remove metoden för att ta bort en rubrik från WebHeaderCollection. När rubriken har tagits bort skriver det här exemplet ut alla befintliga rubriker på skärmen för att bevisa att den har tagits bort.

    myWebHeaderCollection.Set("Cache-Control", "no-cache");

Remove tar bort det angivna huvudet från samlingen. Om det angivna huvudet inte finns returnerar metoden.
