Methods
| Name | Description | |
|---|---|---|
 | Add |
Adds an object to the end of the collection.
|
| Clear |
Removes all items from the collection.
|
| Contains(Guid) |
This method determines whether the collection contains a specific item referenced by id.
|
| Contains(T) |
This method determines whether the collection contains a specific item.
|
| CopyTo |
Copies the entire collection to a compatible one-dimensional Array,
starting at the specified index of the target array.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetEnumerator |
Returns an enumerator that iterates through the collection.
|
| GetHashCode |
Gets the hash code for this instance of the object which is suitable for use in hashing
algorithms and data structures like a hash table.
(Inherited from AFCollection.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IndexOf |
Searches for the specified object and returns the zero-based index of the first
occurrence within the entire collection.
|
| Remove(Guid) |
Removes the item with the specified id from the collection.
|
| Remove(T) |
Removes the first occurrence of a specific object from the collection.
|
| RemoveAt |

|
| Sort |
Sorts the items in the entire collection using the default comparer.
|
| Sort(IComparerT) |
Sorts the items in the entire collection using the specified comparer.
|
| Sort(Int32, Int32, IComparerT) |
Sorts the items in a range of items in the collection using the specified comparer.
|
| ToString |
Returns a String that represents the current object.
