SemanticValue.Value Property

 

A read-only property that returns the information contained in the current SemanticValue.

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

public object Value { get; internal set; }

Property Value

Type: System.Object

Returns an Object instance containing the information stored in the current SemanticValue instance.

Recognition results which do not make use of semantic parsing always have a Value of null and a Count property of zero.

The following example is used to recursively traverse and then display information (including confidence) as a TreeNodeCollection, or as the nodes making up the tree structure of the semantics used to recognize a phrase.

internal static void CreateSemanticsTreeNodes(
          TreeNodeCollection nodes,
          SemanticValue semantics,
          String name) 
{
  string semanticsText = 
      String.Format("  {0} ( Confidence {1})", name,semantics.Confidence);

  // Format integers as hexadecimal.
  if (semantics.Value == null )
  {
    semanticsText = semanticsText + " = null";
  }
  else if (semantics.Value.GetType() == typeof(int)) 
  {
    semanticsText = String.Format("{0} = {1:X} ", semanticsText, semantics.Value);
  }
  else 
  {
    semanticsText = semanticsText + " = " + semantics.Value.ToString();
  }

  TreeNode semanticsNode = new TreeNode(semanticsText);
  foreach (KeyValuePair<String, SemanticValue> child in semantics) 
  {
    CreateSemanticsTreeNodes(semanticsNode.Nodes, child.Value, child.Key);
  }
  nodes.Add(semanticsNode);
}
