CompilationSection Class

Defines configuration settings that are used to support the compilation infrastructure of Web applications. This class cannot be inherited.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)
public sealed class CompilationSection : ConfigurationSection
public final class CompilationSection extends ConfigurationSection
public final class CompilationSection extends ConfigurationSection
Not applicable.

The CompilationSection class provides a way to programmatically access and modify the content of the compilation section of the configuration file.

This example demonstrates how to specify values declaratively for several attributes of the compilation section, which can also be accessed as members of the CompilationSection class.

The following configuration file example shows how to specify values declaratively for the compilation section.

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

The following code example demonstrates how to use members of the CompilationSection class.
