GrammarBuilder.Addition Operator (GrammarBuilder, GrammarBuilder)

Creates a new GrammarBuilder that contains a sequence of two GrammarBuilder objects.

Namespace:  System.Speech.Recognition
Assembly:  System.Speech (in System.Speech.dll)

public static GrammarBuilder operator +(
	GrammarBuilder builder1,
	GrammarBuilder builder2
)

Parameters

builder1
Type: System.Speech.Recognition.GrammarBuilder

The first grammar element.

builder2
Type: System.Speech.Recognition.GrammarBuilder

The second grammar element.

Return Value

Type: System.Speech.Recognition.GrammarBuilder
Returns a GrammarBuilder for the sequence of the builder1 parameter followed by the builder2 parameter.

GrammarBuilder supports conversions from the following classes.

This method accepts the objects listed above for the builder1 and builder2 parameters. For more information, see the Implicit operators.

Important noteImportant

When you combine GrammarBuilder objects that contain SemanticResultValue or SemanticResultKey instances, make sure you avoid creating duplicate semantic elements with the same key name or multiple semantic elements that could repeatedly modify the Value property of a SemanticValue object. The speech recognizer can throw an exception if it encounters these circumstances. For more information about building a speech recognition grammar that contains semantic information, see Understanding SemanticResultValue and SemanticResultKey Objects.
