The PropertyCollection type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | PropertyCollection() | Initializes a new instance of the PropertyCollection class. |
![]() | PropertyCollection(SerializationInfo, StreamingContext) | Initializes a new instance of the PropertyCollection class. |
| Name | Description | |
|---|---|---|
![]() ![]() | comparer | Obsolete. Gets or sets the IComparer to use for the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | Count | Gets the number of key/value pairs contained in the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | EqualityComparer | Gets the IEqualityComparer to use for the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | hcp | Obsolete. Gets or sets the object that can dispense hash codes. (Inherited from Hashtable.) |
![]() ![]() | IsFixedSize | Gets a value indicating whether the Hashtable has a fixed size. (Inherited from Hashtable.) |
![]() ![]() | IsReadOnly | Gets a value indicating whether the Hashtable is read-only. (Inherited from Hashtable.) |
![]() ![]() | IsSynchronized | Gets a value indicating whether access to the Hashtable is synchronized (thread safe). (Inherited from Hashtable.) |
![]() ![]() | Item | Gets or sets the value associated with the specified key. (Inherited from Hashtable.) |
![]() ![]() | Keys | Gets an ICollection containing the keys in the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | SyncRoot | Gets an object that can be used to synchronize access to the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | Values | Gets an ICollection containing the values in the Hashtable. (Inherited from Hashtable.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Add | Adds an element with the specified key and value into the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | Clear | Removes all elements from the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | Clone | Creates a shallow copy of the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | Contains | Determines whether the Hashtable contains a specific key. (Inherited from Hashtable.) |
![]() ![]() | ContainsKey | Determines whether the Hashtable contains a specific key. (Inherited from Hashtable.) |
![]() ![]() | ContainsValue | Determines whether the Hashtable contains a specific value. (Inherited from Hashtable.) |
![]() ![]() | CopyTo | Copies the Hashtable elements to a one-dimensional Array instance at the specified index. (Inherited from Hashtable.) |
![]() ![]() | 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 Hashtable. (Inherited from Hashtable.) |
![]() ![]() | GetHash | Returns the hash code for the specified key. (Inherited from Hashtable.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetObjectData | Implements the ISerializable interface and returns the data needed to serialize the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | KeyEquals | Compares a specific Object with a specific key in the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnDeserialization | Implements the ISerializable interface and raises the deserialization event when the deserialization is complete. (Inherited from Hashtable.) |
![]() ![]() | Remove | Removes the element with the specified key from the Hashtable. (Inherited from Hashtable.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The PropertyCollection can be accessed through the ExtendedProperties property of the DataColumn, DataSet, or DataTable class.
Add custom properties to the DataColumn, DataSet, or DataTable objects through the PropertyCollection. For example, you may want to store the time of the object's creation for later comparison to another object.
