Members| All Members | Constructors | Methods | Properties | ||
| Icon | Member | Description |
|---|---|---|
 | NullSafeCollectionBase()()() | Initializes a new instance of the NullSafeCollectionBase class |
| Add(Object) |
Adds an item to the IList.
|
 | IList..::.Add(Object) | (Inherited from CollectionBase.) |
 | Capacity | Gets or sets the number of elements that the CollectionBase can contain. (Inherited from CollectionBase.) |
 | Clear()()() | Removes all objects from the CollectionBase instance. (Inherited from CollectionBase.) |
| Contains(Object) |
Determines whether the IList contains a specific value.
|
| IList..::.Contains(Object) | (Inherited from CollectionBase.) |
| CopyTo(Array, Int32) |
Copies the elements of the ICollection to an Array, starting at a particular arrayindex.
|
| ICollection..::.CopyTo(Array, Int32) | (Inherited from CollectionBase.) |
| Count | Gets the number of elements contained in the CollectionBase instance. (Inherited from CollectionBase.) |
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| Finalize()()() | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetEnumerator()()() | Returns an enumerator that iterates through the CollectionBase instance. (Inherited from CollectionBase.) |
| GetHashCode()()() | Serves as a hash function for a particular type. GetHashCode()()() is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.) |
| GetType()()() | Gets the Type of the current instance. (Inherited from Object.) |
| IndexOf(Object) |
Determines the index of a specific item in the IList.
|
| IList..::.IndexOf(Object) | (Inherited from CollectionBase.) |
 | InnerList | Gets an ArrayList containing the list of elements in the CollectionBase instance. (Inherited from CollectionBase.) |
| Insert(Int32, Object) |
Inserts an item to the IList at the specified position.
|
| IList..::.Insert(Int32, Object) | (Inherited from CollectionBase.) |
| IsFixedSize |
Gets a value indicating whether the IList has a fixed size.
|
 | IList..::.IsFixedSize | (Inherited from CollectionBase.) |
| IsReadOnly |
Gets a value indicating whether the IList is read-only.
|
| IList..::.IsReadOnly | (Inherited from CollectionBase.) |
| IsSynchronized |
Gets a value indicating whether access to the ICollection is synchronized (thread-safe).
|
| ICollection..::.IsSynchronized | (Inherited from CollectionBase.) |
| Item[([(Int32])]) |
Gets or sets the item at the specified index.
|
| IList..::.Item[([(Int32])]) | (Inherited from CollectionBase.) |
| List | Gets an IList containing the list of elements in the CollectionBase instance. (Inherited from CollectionBase.) |
| MemberwiseClone()()() | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnClear()()() | Performs additional custom processes when clearing the contents of the CollectionBase instance. (Inherited from CollectionBase.) |
| OnClearComplete()()() | Performs additional custom processes after clearing the contents of the CollectionBase instance. (Inherited from CollectionBase.) |
| OnInsert(Int32, Object) | Performs additional custom processes before inserting a new element into the CollectionBase instance. (Inherited from CollectionBase.) |
| OnInsertComplete(Int32, Object) | Performs additional custom processes after inserting a new element into the CollectionBase instance. (Inherited from CollectionBase.) |
| OnRemove(Int32, Object) | Performs additional custom processes when removing an element from the CollectionBase instance. (Inherited from CollectionBase.) |
| OnRemoveComplete(Int32, Object) | Performs additional custom processes after removing an element from the CollectionBase instance. (Inherited from CollectionBase.) |
| OnSet(Int32, Object, Object) | Performs additional custom processes before setting a value in the CollectionBase instance. (Inherited from CollectionBase.) |
| OnSetComplete(Int32, Object, Object) | Performs additional custom processes after setting a value in the CollectionBase instance. (Inherited from CollectionBase.) |
| OnValidate(Object) | Performs additional custom processes when validating a value. (Inherited from CollectionBase.) |
| Remove(Object) |
Removes the first occurrence of a specific item from the IList.
|
| IList..::.Remove(Object) | (Inherited from CollectionBase.) |
| RemoveAt(Int32) | Removes the element at the specified index of the CollectionBase instance. (Inherited from CollectionBase.) |
| SyncRoot |
Gets an Object that can be used to synchronize access to the ICollection.
|
| ICollection..::.SyncRoot | (Inherited from CollectionBase.) |
| ToString()()() | Returns a String that represents the current Object. (Inherited from Object.) |
