示例

本部分中的示例演示如何在访问配置文件中的相关节信息后获取 AllowDefinition 属性值。

以下示例获取 SectionInformation 对象。

// Get the current configuration file.
System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);

// Get the section.
UrlsSection section =
    (UrlsSection)config.GetSection("MyUrls");

SectionInformation sInfo =
    section.SectionInformation;

' Get the current configuration file.
Dim config _
As System.Configuration.Configuration = _
ConfigurationManager.OpenExeConfiguration( _
ConfigurationUserLevel.None)

' Get the section.
Dim section As UrlsSection = _
CType(config.GetSection("MyUrls"), UrlsSection)

Dim sInfo As SectionInformation = _
section.SectionInformation

以下示例获取 AllowDefinition 值。

ConfigurationAllowDefinition allowDefinition =
    sInfo.AllowDefinition;
Console.WriteLine("Allow definition: {0}", 
    allowDefinition.ToString() );

Dim allowDefinition _
As ConfigurationAllowDefinition = _
sInfo.AllowDefinition
Console.WriteLine("Allow definition: {0}", _
allowDefinition.ToString())

注解

AllowDefinition 仅适用于 Web 应用程序的配置文件。 对于客户端应用程序，必须使用 AllowExeDefinition。
