SectionInformation.IsDeclarationRequired 属性

定义

命名空间:

System.Configuration

程序集:

System.Configuration.ConfigurationManager.dll

包:

System.Configuration.ConfigurationManager v8.0.0

Source:

SectionInformation.cs

获取一个值，该值指示是否必须在配置文件中声明该配置节。

public:
 property bool IsDeclarationRequired { bool get(); };

public bool IsDeclarationRequired { get; }

member this.IsDeclarationRequired : bool

Public ReadOnly Property IsDeclarationRequired As Boolean

属性值

Boolean

如果必须在配置文件中声明关联的 ConfigurationSection 对象，则为 true；否则为 false。

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 IsDeclarationRequired 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 IsDeclarationRequired 值。

bool declRequired = 
    sInfo.IsDeclarationRequired;
Console.WriteLine("Declaration required?: {0}",
    declRequired.ToString());

Dim declRequired As Boolean = _
sInfo.IsDeclarationRequired
Console.WriteLine("Declaration required?: {0}", _
declRequired.ToString())
