Voorbeelden

Deze sectie bevat twee codevoorbeelden. De eerste laat zien hoe u declaratief waarden opgeeft voor verschillende eigenschappen van de BuildProviderCollection klasse. De tweede laat zien hoe u leden van de BuildProviderCollection klasse gebruikt.

In het volgende voorbeeld van een configuratiebestand ziet u hoe u declaratief waarden opgeeft voor verschillende eigenschappen van de BuildProviderCollection klasse.

<system.web>
  <compilation>
    <buildProviders>
      <add extension=".aspx"
        type="System.Web.Compilation.PageBuildProvider"
         />
      <add extension=".ascx"
        type="System.Web.Compilation.UserControlBuildProvider"
         />
      <add extension=".master"
        type="System.Web.Compilation.MasterPageBuildProvider"
         />
      <add extension=".asix"
        type="System.Web.Compilation.ImageGeneratorBuildProvider"
         />
      <add extension=".asmx"
        type="System.Web.Compilation.WebServiceBuildProvider"
         />
      <add extension=".ashx"
        type="System.Web.Compilation.WebHandlerBuildProvider"
         />
      <add extension=".soap"
        type="System.Web.Compilation.WebServiceBuildProvider"
         />
      <add extension=".resx"
        type="System.Web.Compilation.ResXBuildProvider"
        appliesTo="Resources" />
      <add extension=".resources"
        type="System.Web.Compilation.ResourcesBuildProvider"
        appliesTo="Code, Resources" />
      <add extension=".wsdl"
        type="System.Web.Compilation.WsdlBuildProvider"
        appliesTo="Code" />
      <add extension=".xsd"
        type="System.Web.Compilation.XsdBuildProvider"
        appliesTo="Code" />
    </buildProviders>
  </compilation>
</system.web>

In het volgende codevoorbeeld ziet u hoe u leden van de BuildProviderCollection klasse gebruikt.

Opmerkingen

Deze BuildProviderCollection wordt gebruikt om aangepaste resourcebestanden te compileren. U kunt een willekeurig aantal buildproviders hebben. Het BuildProviderCollection verwijst niet naar een werkelijk element in het onderliggende configuratiebestand. Het is een constructie die eenvoudige toegang biedt tot de compilatie-informatie die deze bevat.
