PropertyDataCollection Class

Represents the set of properties of a WMI object.


Namespace:  System.Management
Assembly:  System.Management (in System.Management.dll)

Public Class PropertyDataCollection _
	Implements ICollection, IEnumerable

The PropertyDataCollection type exposes the following members.

Public propertyCountGets the number of objects in the PropertyDataCollection.
Public propertyIsSynchronizedGets a value indicating whether the object is synchronized.
Public propertyItemGets the specified property from the PropertyDataCollection, using [] syntax. This property is the indexer for the PropertyDataCollection class.
Public propertySyncRootGets the object to be used for synchronization.

Public methodAdd(String, Object)Adds a new PropertyData with the specified value. The value cannot be null and must be convertible to a Common Information Model (CIM) type.
Public methodAdd(String, CimType, Boolean)Adds a new PropertyData with no assigned value.
Public methodAdd(String, Object, CimType)Adds a new PropertyData with the specified value and Common Information Model (CIM) type.
Public methodCopyTo(Array, Int32)Copies the PropertyDataCollection into an array.
Public methodCopyTo(PropertyData(), Int32)Copies the PropertyDataCollection to a specialized PropertyData object array.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorReturns the enumerator for this PropertyDataCollection.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRemoveRemoves a PropertyData from the PropertyDataCollection.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast(Of TResult)Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType(Of TResult)Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)

Explicit interface implemetationPrivate methodIEnumerable.GetEnumeratorReturns an IEnumerator that iterates through the PropertyDataCollection.
