Public Class PropertyDataCollection
	Implements ICollection, IEnumerable

NameDescription
System_CAPS_pubpropertyCount

Gets the number of objects in the PropertyDataCollection.

System_CAPS_pubpropertyIsSynchronized

Gets a value indicating whether the object is synchronized.

System_CAPS_pubpropertyItem(String)

Gets the specified property from the PropertyDataCollection, using [] syntax. This property is the indexer for the PropertyDataCollection class.

System_CAPS_pubpropertySyncRoot

Gets the object to be used for synchronization.

NameDescription
System_CAPS_pubmethodAdd(String, CimType, Boolean)

Adds a new PropertyData with no assigned value.

System_CAPS_pubmethodAdd(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.

System_CAPS_pubmethodAdd(String, Object, CimType)

Adds a new PropertyData with the specified value and Common Information Model (CIM) type.

System_CAPS_pubmethodCopyTo(Array, Int32)

Copies the PropertyDataCollection into an array.

System_CAPS_pubmethodCopyTo(PropertyData(), Int32)

Copies the PropertyDataCollection to a specialized PropertyData object array.

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetEnumerator()

Returns the enumerator for this PropertyDataCollection.

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodRemove(String)

Removes a PropertyData from the PropertyDataCollection.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodIEnumerable.GetEnumerator()

Returns an IEnumerator that iterates through the PropertyDataCollection.

NameDescription
System_CAPS_pubmethodAsParallel()

Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)

System_CAPS_pubmethodAsQueryable()

Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)

System_CAPS_pubmethodCast(Of TResult)()

Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)

System_CAPS_pubmethodOfType(Of TResult)()

Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)
