Gets the collection of cells selected by the user.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The property is always populated regardless of the SelectionMode property value.
This property contains a read-only snapshot of the selection at the time it is referenced. If you hold onto a copy of this collection, it may differ from the actual, subsequent DataGridView state in which the user may have changed the selection. Therefore, you should not operate on a copy of the collection.
The following code example demonstrates how to use the collection to find the sum of the values in the selection. In the example, this collection is iterated through and the valid values are added to the sum, which is displayed in a label. This example is part of a larger example available in the SelectionChanged event.
