定义用于支持 Web 应用程序的编译基础结构的配置设置。 此类不能被继承。

public ref class CompilationSection sealed : System::Configuration::ConfigurationSection

public sealed class CompilationSection : System.Configuration.ConfigurationSection

type CompilationSection = class
    inherit ConfigurationSection

Public NotInheritable Class CompilationSection
Inherits ConfigurationSection

继承

Object

ConfigurationSection

CompilationSection

示例

此示例演示如何为节的 compilation 多个属性以声明方式指定值，该属性也可以作为类的成员 CompilationSection 进行访问。

以下配置文件示例演示如何以声明方式为 compilation 节指定值。

<system.web>  
  <compilation   
    tempDirectory=""   
    debug="False"   
    strict="False"   
    explicit="True"   
    batch="True"   
    batchTimeout="900"   
    maxBatchSize="1000"   
    maxBatchGeneratedFileSize="1000"   
    numRecompilesBeforeAppRestart="15"   
    defaultLanguage="vb"   
    targetFramework="4.0"   
    urlLinePragmas="False"   
    assemblyPostProcessorType="">  
    <assemblies>  
      <clear />  
    </assemblies>  
    <buildProviders>  
      <clear />  
    </buildProviders>  
    <expressionBuilders>  
      <clear />  
    </expressionBuilders>  
  </compilation>   
</system.web>  

下面的代码示例演示如何使用类的成员 CompilationSection 。
