public BarCommandCollection()

Properties

Count

Gets the number of elements contained in the BarCommandCollection instance.

public virtual int Count { get; }

Property Value

int:: The number of elements contained in the BarCommandCollection instance.

InnerList

Gets the list of items contained in the collection instance.

protected ArrayList InnerList { get; }

Property Value

ArrayList:: An ArrayList representing the collection instance itself.

IsFixedSize

Gets a value indicating whether the collection has a fixed size.

public virtual bool IsFixedSize { get; }

Property Value

bool:: true if the collection has a fixed size; otherwise, false.

Remarks

A collection with a fixed size does not allow the addition or removal of elements, but it allows the modification of existing elements.

this[string]

Gets the BarCommand with the specified FullName.

[C#] In C#, this property is the indexer for the BarCommandCollection class.

public BarCommand this[string fullName] { get; }

Parameter	Type	Description
fullName	string	The FullName of the BarCommand to return.

Property Value

BarCommand:: The BarCommand with the specified FullName.

SyncRoot

Gets an Object that can be used to synchronize access to the collection.

public virtual object SyncRoot { get; }

Property Value

object:: An Object that can be used to synchronize access to the collection.

Methods

Add(BarCommand)

Adds a BarCommand to the end of the collection.

public int Add(BarCommand value)

Parameter	Type	Description
value	BarCommand	The BarCommand to be added to the end of the collection.

Returns

int:: The collection index at which the BarCommand has been added.

AddRange(BarCommand[])

Adds multiple BarCommand objects to the collection.

public void AddRange(BarCommand[] items)

Parameter	Type	Description
items	BarCommand[]	The array of BarCommand objects to add.

Clear()

Removes all BarCommand objects from the collection.

public void Clear()

Contains(BarCommand)

Returns whether the specified BarCommand is in the collection.

public virtual bool Contains(BarCommand value)

Parameter	Type	Description
value	BarCommand	The BarCommand to locate in the collection.

Returns

bool:: true if the BarCommand is found in the collection; otherwise, false.

Contains(string)

Determines whether a BarCommand is in the collection with the specified FullName.

public virtual bool Contains(string fullName)

Parameter	Type	Description
fullName	string	The FullName of the BarCommand to locate in the collection.

Returns

bool:: true if the name is found in the collection; otherwise, false.

CopyTo(Array, int)

Copies the entire collection to a compatible one-dimensional Array, starting at the specified index of the target array.

public virtual void CopyTo(Array array, int arrayIndex)

Parameter	Type	Description
array	Array	The one-dimensional `Array` that is the destination of the elements copied from the collection. The `Array` must have zero-based indexing.
arrayIndex	int	The zero-based index in `array` at which copying begins.

GetEnumerator()

Retrieves an IEnumerator object for the entire collection.

public virtual IEnumerator GetEnumerator()

Returns

IEnumerator:: An IEnumerator object for the entire collection

Remarks

Enumerators are intended to be used only to read data in the collection. Enumerators cannot be used to modify the underlying collection.

The enumerator does not have exclusive access to the collection.

When an enumerator is instantiated, it takes a snapshot of the current state of the collection. If changes are made to the collection, such as adding, modifying or deleting elements, the snapshot gets out of sync and the enumerator throws an InvalidOperationException. Two enumerators instantiated from the same collection at the same time can have different snapshots of the collection.

IndexOf(BarCommand)

Searches for the specified BarCommand and returns the zero-based index of the first occurrence within the entire collection.

public virtual int IndexOf(BarCommand value)

Parameter	Type	Description
value	BarCommand	The BarCommand to locate in the collection.

Returns

int:: The zero-based index of the first occurrence of the BarCommand within the entire collection, if found; otherwise, -1.

IndexOf(string)

Searches for the specified FullName of a BarCommand and returns the zero-based index of the first occurrence within the entire collection.

public virtual int IndexOf(string fullName)

Parameter	Type	Description
fullName	string	The FullName of the BarCommand to locate in the collection.

Returns

int:: The zero-based index of the first occurrence of the FullName within the entire collection, if found; otherwise, -1.

Insert(int, BarCommand)

Inserts a BarCommand into the collection at the specified index.

public void Insert(int index, BarCommand value)

Parameter	Type	Description
index	int	The zero-based index at which the BarCommand should be inserted.
value	BarCommand	The BarCommandto insert.

OnObjectAdded(int, BarCommand)

Performs additional custom processes after an object is added to the collection.

protected virtual void OnObjectAdded(int index, BarCommand value)

Parameter	Type	Description
index	int	The zero-based index at which the object was inserted.
value	BarCommand	The object that was inserted.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is added.

OnObjectAdding(int, BarCommand)

Performs additional custom processes before an object is added to the collection.

protected virtual void OnObjectAdding(int index, BarCommand value)

Parameter	Type	Description
index	int	The zero-based index at which the object was inserted.
value	BarCommand	The object that was inserted.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is added.

OnObjectRemoved(int, BarCommand)

Performs additional custom processes after an object is removed from the collection.

protected virtual void OnObjectRemoved(int index, BarCommand value)

Parameter	Type	Description
index	int	The zero-based index from which the object was removed.
value	BarCommand	The object that was removed.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is removed.

OnObjectRemoving(int, BarCommand)

Performs additional custom processes before an object is removed from the collection.

protected virtual void OnObjectRemoving(int index, BarCommand value)

Parameter	Type	Description
index	int	The zero-based index from which the object was removed.
value	BarCommand	The object that was removed.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action before the specified object is removed.

OnValidate(BarCommand, int)

Performs additional custom processes when validating a value.

protected virtual void OnValidate(BarCommand value, int existingIndex)

Parameter	Type	Description
value	BarCommand	The object to validate.
existingIndex	int	The index within the collection of the object that would be replaced by the value.

Remarks

The default implementation of this method determines whether value is null, and if so, throws ArgumentNullException. It is intended to be overridden by a derived class to perform additional action when the specified element is validated.

Remove(BarCommand)

Removes the first occurrence of a specific BarCommand from the collection.

public void Remove(BarCommand value)

Parameter	Type	Description
value	BarCommand	The BarCommand to remove from the collection.

Remarks

The elements that follow the removed element move up to occupy the vacated spot. The indexes of the elements that are moved are also updated.

RemoveAt(int)

Removes the BarCommand at the specified index of the collection.

public void RemoveAt(int index)

Parameter	Type	Description
index	int	The zero-based index of the BarCommand to remove.

Remarks

The elements that follow the removed element move up to occupy the vacated spot. The indexes of the elements that are moved are also updated.
