Remarks

The WizardStepCollection class is used to store and manage a collection of WizardStepBase-derived objects in a control that acts as a wizard, such as the CreateUserWizard control or the Wizard control. For example, the Wizard control uses the WizardStepCollection class for its WizardSteps property.

There are multiple ways you can access the WizardStepBase-derived objects in the WizardStepCollection:

Use the Item[] property to directly access a WizardStepBase-derived object at a specific zero-based index.
Use the GetEnumerator method to create an enumerator that can be used to iterate through the collection.
Use the CopyTo method to copy the contents of the WizardStepCollection collection into an Array object.

Properties

Count	Gets the number of WizardStepBase-derived objects in the Wizard control's WizardStepCollection collection.
IsReadOnly	Gets a value indicating whether the WizardStepBase-derived objects in the collection can be modified.
IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread-safe).
Item[Int32]	Gets a WizardStepBase-derived object from the collection at the specified index.
SyncRoot	Gets an object that can be used to synchronize access to the collection.

Methods

Add(WizardStepBase)	Appends the specified WizardStepBase-derived object to the end of the collection.
AddAt(Int32, WizardStepBase)	Adds the specified WizardStepBase-derived object to the collection at the specified index location.
Clear()	Removes all WizardStepBase-derived objects from the collection.
Contains(WizardStepBase)	Determines whether the WizardStepCollection collection contains a specific WizardStepBase-derived object.
CopyTo(WizardStepBase[], Int32)	Copies all the items from a WizardStepCollection collection to a compatible one-dimensional array of WizardStepBase objects, starting at the specified index in the target array.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns an IEnumerator-implemented object that can be used to iterate through the WizardStepBase-derived objects in the collection.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IndexOf(WizardStepBase)	Determines the index value that represents the position of the specified WizardStepBase-derived object in the collection.
Insert(Int32, WizardStepBase)	Inserts the specified WizardStepBase-derived object into the collection at the specified index location.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(WizardStepBase)	Removes the specified WizardStepBase-derived object from the collection.
RemoveAt(Int32)	Removes the WizardStepBase-derived object from the collection at the specified location.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)	Copies all the items from a WizardStepCollection collection to a one-dimensional array, starting at the specified index in the target array.
IList.Add(Object)	Appends the specified object to the end of the collection.
IList.Contains(Object)	Determines whether the collection contains the specified object.
IList.IndexOf(Object)	Determines the index value that represents the position of the specified object in the collection.
IList.Insert(Int32, Object)	Inserts the specified object in the collection at the specified position.
IList.IsFixedSize	Gets a value indicating whether the collection has a fixed size.
IList.Item[Int32]	Gets the object at the specified index in the collection.
IList.Remove(Object)	Removes the specified object from the collection.

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
