The PropertyInformationCollection type exposes the following members.

Properties
  Name Description
Public property Count Gets the number of key/value pairs contained in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected property IsReadOnly Gets or sets a value indicating whether the NameObjectCollectionBase instance is read-only. (Inherited from NameObjectCollectionBase.)
Public property Item Gets the PropertyInformation object in the collection, based on the specified property name.
Public property Keys Gets a NameObjectCollectionBase.KeysCollection instance that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Top
Methods
  Name Description
Protected method BaseAdd Adds an entry with the specified key and value into the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseClear Removes all entries from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGet(Int32) Gets the value of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGet(String) Gets the value of the first entry with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGetAllKeys Returns a String array that contains all the keys in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGetAllValues() Returns an Object array that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGetAllValues(Type) Returns an array of the specified type that contains all the values in the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseGetKey Gets the key of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseHasKeys Gets a value indicating whether the NameObjectCollectionBase instance contains entries whose keys are not null. (Inherited from NameObjectCollectionBase.)
Protected method BaseRemove Removes the entries with the specified key from the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseRemoveAt Removes the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseSet(Int32, Object) Sets the value of the entry at the specified index of the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Protected method BaseSet(String, Object) Sets the value of the first entry with the specified key in the NameObjectCollectionBase instance, if found; otherwise, adds an entry with the specified key and value into the NameObjectCollectionBase instance. (Inherited from NameObjectCollectionBase.)
Public method CopyTo Copies the entire PropertyInformationCollection collection to a compatible one-dimensional Array, starting at the specified index of the target array.
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetEnumerator Gets an IEnumerator object, which is used to iterate through this PropertyInformationCollection collection. (Overrides NameObjectCollectionBase.GetEnumerator().)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetObjectData Populates a SerializationInfo object with the data needed to serialize the PropertyInformationCollection instance. (Overrides NameObjectCollectionBase.GetObjectData(SerializationInfo, StreamingContext).)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method OnDeserialization Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from NameObjectCollectionBase.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations
  Name Description
Explicit interface implemetation Private method ICollection.CopyTo Copies the entire NameObjectCollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from NameObjectCollectionBase.)
Explicit interface implemetation Private property ICollection.IsSynchronized Gets a value indicating whether access to the NameObjectCollectionBase object is synchronized (thread safe). (Inherited from NameObjectCollectionBase.)

Remarks

The PropertyInformationCollection object contains a collection of PropertyInformation objects. A PropertyInformation object contains the details of an individual attribute within the configuration. The PropertyInformationCollection object is derived from the associated NameObjectCollectionBase object.

Examples

The following code example demonstrates how to use the PropertyInformationCollection class.

Visual Basic

' 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)
C#

// 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);
