    <summary>Encapsulates the collection of indexes of checked items (including items in an indeterminate state) in a <see cref="T:System.Windows.Forms.CheckedListBox" />.</summary>
    <remarks>

## Remarks  
 The checked indexes collection is a subset of the indexes into the collection of all items in the <xref:System.Windows.Forms.CheckedListBox> control. These indexes specify items in a checked or indeterminate state.  
  
 The following table is an example of the indexed collection of items in the control (all items contained in the control).  
  
|Index|Item|Check State|  
|-----------|----------|-----------------|  
|0|object 1|<xref:System.Windows.Forms.CheckState.Unchecked>|  
|1|object 2|<xref:System.Windows.Forms.CheckState.Checked>|  
|2|object 3|<xref:System.Windows.Forms.CheckState.Unchecked>|  
|3|object 4|<xref:System.Windows.Forms.CheckState.Indeterminate>|  
|4|object 5|<xref:System.Windows.Forms.CheckState.Checked>|  
  
 Based on the previous example, the following table shows the indexed collection of indexes of checked items.  
  
|Index|Index of Item|  
|-----------|-------------------|  
|0|1|  
|1|3|  
|2|4|  
  
 The <xref:System.Windows.Forms.CheckedListBox> class has two members that allow you to access the stored indexes, the <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection.Item%2A> property and the <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection.IndexOf%2A> method.  
  
 Based on the previous example, a call to the <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection.Item%2A> property with a parameter value of 1 returns a value of 3. A call to <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection.IndexOf%2A> with a parameter of 3 returns a value of 1.  
  
   
  
## Examples  
 The following example enumerates the checked items in the <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection> to see what check state an item is in. The example demonstrates using the <xref:System.Windows.Forms.CheckedListBox.GetItemCheckState%2A> method to set the check state of an item. The example also demonstrates using the <xref:System.Windows.Forms.CheckedListBox.CheckedIndices%2A> property to get the <xref:System.Windows.Forms.CheckedListBox.CheckedIndexCollection>, and the <xref:System.Windows.Forms.CheckedListBox.CheckedItems%2A> property to get the <xref:System.Windows.Forms.CheckedListBox.CheckedItemCollection>.  
  
 The first loop uses the <xref:System.Windows.Forms.CheckedListBox.GetItemCheckState%2A> method to get the <xref:System.Windows.Forms.CheckState> of each checked item, given the index of the item. The second loop also uses <xref:System.Windows.Forms.CheckedListBox.GetItemCheckState%2A>, but uses the <xref:System.Windows.Forms.ListBox.ObjectCollection.IndexOf%2A?displayProperty=nameWithType> method to retrieve the index for the item.
