Properties

Count	Gets the number of objects in the PropertyDataCollection.
IsSynchronized	Gets a value indicating whether the object is synchronized.
Item[String]	Gets the specified property from the PropertyDataCollection, using [] syntax. This property is the indexer for the PropertyDataCollection class.
SyncRoot	Gets the object to be used for synchronization.

Methods

Add(String, CimType, Boolean)	Adds a new PropertyData with no assigned value.
Add(String, Object, CimType)	Adds a new PropertyData with the specified value and Common Information Model (CIM) type.
Add(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.
CopyTo(Array, Int32)	Copies the PropertyDataCollection into an array.
CopyTo(PropertyData[], Int32)	Copies the PropertyDataCollection to a specialized PropertyData object array.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns the enumerator for this PropertyDataCollection.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(String)	Removes a PropertyData from the PropertyDataCollection.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

IEnumerable.GetEnumerator()

Returns an IEnumerator that iterates through the PropertyDataCollection.

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
