Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public void SetTextDecorations(
	TextDecorationCollection textDecorations,
	int startIndex,
	int count
)

Parameters

textDecorations
Type: System.Windows.TextDecorationCollection

The TextDecorationCollection to apply to the text.

startIndex
Type: System.Int32

The start index of the initial character to apply the text decorations to.

count

The TextDecorationCollection class specifies the types of text decorations to apply to the text. There are four types of text decorations: underline, baseline, strikethrough, and overline. These are described as TextDecorationLocation values that are set on each item in the TextDecorationCollection. It is common that the TextDecorationCollection collection contains only one decoration, but the property uses the collection to provide for more advanced decoration effects by applying multiple decorations to the same text.

The following illustration shows the locations of the text decorations relative to the text.

Example of text decoration types

To set the TextDecorationCollection for the entire text string, use the SetTextDecorations(TextDecorationCollection) method.
