InstanceDataCollection Class
Provides a strongly typed collection of InstanceData objects.
Assembly: System (in System.dll)
The InstanceDataCollection type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | InstanceDataCollection | Obsolete. Initializes a new instance of the InstanceDataCollection class, using the specified performance counter (which defines a performance instance). |
| Name | Description | |
|---|---|---|
![]() | Count | Gets the number of elements contained in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | CounterName | Gets the name of the performance counter whose instance data you want to get. |
![]() | Dictionary | Gets the list of elements contained in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | InnerHashtable | Gets the list of elements contained in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | Item | Gets the instance data associated with this counter. This is typically a set of raw counter values. |
![]() | Keys | Gets the object and counter registry keys for the objects associated with this instance data. |
![]() | Values | Gets the raw counter values that comprise the instance data for the counter. |
| Name | Description | |
|---|---|---|
![]() | Clear | Clears the contents of the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | Contains | Determines whether a performance instance with a specified name (identified by one of the indexed InstanceData objects) exists in the collection. |
![]() | CopyTo(Array, Int32) | Copies the DictionaryBase elements to a one-dimensional Array at the specified index. (Inherited from DictionaryBase.) |
![]() | CopyTo(array<InstanceData>, Int32) | Copies the items in the collection to the specified one-dimensional array at the specified index. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetEnumerator | Returns an IDictionaryEnumerator that iterates through the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (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.) |
![]() | OnClear | Performs additional custom processes before clearing the contents of the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnClearComplete | Performs additional custom processes after clearing the contents of the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnGet | Gets the element with the specified key and value in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnInsert | Performs additional custom processes before inserting a new element into the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnInsertComplete | Performs additional custom processes after inserting a new element into the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnRemove | Performs additional custom processes before removing an element from the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnRemoveComplete | Performs additional custom processes after removing an element from the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnSet | Performs additional custom processes before setting a value in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnSetComplete | Performs additional custom processes after setting a value in the DictionaryBase instance. (Inherited from DictionaryBase.) |
![]() | OnValidate | Performs additional custom processes when validating the element with the specified key and value. (Inherited from DictionaryBase.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ICollection::IsSynchronized | Gets a value indicating whether access to a DictionaryBase object is synchronized (thread safe). (Inherited from DictionaryBase.) |
![]() ![]() | ICollection::SyncRoot | Gets an object that can be used to synchronize access to a DictionaryBase object. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Add | Adds an element with the specified key and value into the DictionaryBase. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Contains | Determines whether the DictionaryBase contains a specific key. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::IsFixedSize | Gets a value indicating whether a DictionaryBase object has a fixed size. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::IsReadOnly | Gets a value indicating whether a DictionaryBase object is read-only. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Item | Gets or sets the value associated with the specified key. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Keys | Gets an ICollection object containing the keys in the DictionaryBase object. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Remove | Removes the element with the specified key from the DictionaryBase. (Inherited from DictionaryBase.) |
![]() ![]() | IDictionary::Values | Gets an ICollection object containing the values in the DictionaryBase object. (Inherited from DictionaryBase.) |
![]() ![]() | IEnumerable::GetEnumerator | Returns an IEnumerator that iterates through the DictionaryBase. (Inherited from DictionaryBase.) |
The InstanceDataCollection class represents a collection containing all the instance data for a counter. This collection is contained in the InstanceDataCollectionCollection when using the ReadCategory method.
The following code example displays the instance data for a particular PerformanceCounterCategory on the local computer. It first displays a numbered list of PerformanceCounterCategory names. After the user enters the number of one of the categories, the example gets the InstanceDataCollectionCollection for that PerformanceCounterCategory. It then converts the collection returned by Values to an array of InstanceDataCollection objects. The example also displays the instance data associated with each InstanceData of each InstanceDataCollection.
