The TextSelection class represents the selection of text in the RichTextBox. This type has no public constructor, but you can access the currently selected text in the RichTextBox by using the RichTextBox::Selection property. To perform operations on the selected text, you can use the GetPropertyValue and ApplyPropertyValue methods.
