示例

下面的代码示例演示如何使用 PropertyInformationCollection 类。The following code example demonstrates how to use the PropertyInformationCollection class.

// Create EllementInformation object.
ElementInformation elementInfo =
  configSection.ElementInformation;
// Create a PropertyInformationCollection object.
PropertyInformationCollection propertyInfoCollection =
  elementInfo.Properties;
// Create a PropertyInformation object.
PropertyInformation myPropertyInfo =
  propertyInfoCollection["enabled"];
// Display the property value.
Console.WriteLine
  ("anonymousIdentification Section - Enabled: {0}",
  myPropertyInfo.Value);
' Create EllementInformation object.
Dim elementInfo As ElementInformation = _
configSection.ElementInformation()
' Create a PropertyInformationCollection object.
Dim propertyInfoCollection As PropertyInformationCollection = _
elementInfo.Properties()
' Create a PropertyInformation object.
Dim myPropertyInfo As PropertyInformation = _
  propertyInfoCollection("enabled")
' Display the property value.
Console.WriteLine _
  ("anonymousIdentification Section - Enabled: {0}", _
  myPropertyInfo.Value)

注解

PropertyInformationCollection对象包含对象的集合 PropertyInformationThe PropertyInformationCollection object contains a collection of PropertyInformation objects. PropertyInformation对象包含配置中的单个属性的详细信息。A PropertyInformation object contains the details of an individual attribute within the configuration. PropertyInformationCollection对象派生自关联的 NameObjectCollectionBase 对象。The PropertyInformationCollection object is derived from the associated NameObjectCollectionBase object.
