Represents the collection containing the indexes to the checked items in a list view control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Thetype exposes the following members.
|Contains||Determines whether the specified index is located in the collection.|
|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 enumerator that can be used to iterate through the checked index collection.|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IndexOf||Returns the index within the of the specified index from the ListView.ListViewItemCollection of the list view control.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|AsParallel()||Overloaded. Enables parallelization of a query. (Defined by ParallelEnumerable.)|
|AsParallel()||Overloaded. (Defined by ParallelEnumerable.)|
|AsQueryable()||Overloaded. Converts an IEnumerable to an IQueryable. (Defined by Queryable.)|
|AsQueryable()||Overloaded. (Defined by Queryable.)|
|Cast<TResult>()||Overloaded. Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)|
|Cast<TResult>()||Overloaded. (Defined by Enumerable.)|
|OfType<TResult>()||Overloaded. Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)|
|OfType<TResult>()||Overloaded. (Defined by Enumerable.)|
|ICollection.CopyTo||Infrastructure. Copies the collection of checked-item indexes into an array.|
|ICollection.IsSynchronized||Infrastructure. Gets a value indicating whether access to the collection is synchronized (thread safe).|
|ICollection.SyncRoot||Infrastructure. Gets an object that can be used to synchronize access to the collection of controls.|
|IList.Add||Infrastructure. Adds an item to the collection.|
|IList.Clear||Infrastructure. Removes all items from the collection.|
|IList.Contains||Infrastructure. Checks whether the index corresponding with the ListViewItem is checked.|
|IList.IndexOf||Infrastructure. Returns the index of the specified object in the .|
|IList.Insert||Infrastructure. Inserts an item into the collection at a specified index.|
|IList.IsFixedSize||Infrastructure. Gets a value indicating whether the has a fixed size.|
|IList.Item||Infrastructure. Gets or sets an object in the .|
|IList.Remove||Infrastructure. Removes the first occurrence of an item from the collection.|
|IList.RemoveAt||Infrastructure. Removes an item from the collection at a specified index.|
A stores the indexes to the checked items in a ListView control. Items can be checked only if the CheckBoxes property of the ListView control is set to true. The indexes stored in the are index positions within the ListView.ListViewItemCollection. The ListView.ListViewItemCollection stores all items displayed in the ListView control.
Checked state in the ListView
Based on the ListView.ListViewItemCollection example in the previous table, the following table demonstrates how the would appear.
Index of checked item in ListViewItemCollection
You can use the properties and methods of this class to perform a variety of tasks with the collection. The Contains method enables you to determine whether an index position from the ListView.ListViewItemCollection is one of the indexes stored in the . Once you know that the item is in the collection, you can use the IndexOf method to determine the position of the index in the .
