表示 BuildProvider 对象集合。 此类不能被继承。
public ref class BuildProviderCollection sealed : System::Configuration::ConfigurationElementCollection[System.Configuration.ConfigurationCollection(typeof(System.Web.Configuration.BuildProvider))]
public sealed class BuildProviderCollection : System.Configuration.ConfigurationElementCollection[<System.Configuration.ConfigurationCollection(typeof(System.Web.Configuration.BuildProvider))>]

示例
本部分提供两个代码示例。 第一个示例演示如何以声明方式为类的 BuildProviderCollection 多个属性指定值。 第二个演示如何使用 类的成员 BuildProviderCollection 。
以下配置文件示例演示如何以声明方式为类的 BuildProviderCollection 多个属性指定值。
<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>
下面的代码示例演示如何使用 类的成员 BuildProviderCollection 。
