'Usage
Dim instance As ContextNodeCollection 
Dim returnValue As ContextNodeCollection.ContextNodeCollectionEnumerator 

returnValue = instance.GetEnumerator()
public ContextNodeCollection.ContextNodeCollectionEnumerator GetEnumerator()
public:
ContextNodeCollection.ContextNodeCollectionEnumerator^ GetEnumerator()
public function GetEnumerator() : ContextNodeCollection.ContextNodeCollectionEnumerator

Return Value

Type: Microsoft.Ink.ContextNodeCollection.ContextNodeCollectionEnumerator
An object that both implements the IEnumerator interface, and can iterate through the ContextNode objects within the ContextNodeCollection.

Examples

The examples in this section show two ways to iterate over a ContextNodeCollection and get the identifiers for all of the lines in an InkAnalyzer, theInkAnalyzer.

The following example gets the IEnumerator for the ContextNodeCollection, lines.

Dim ids As New ArrayList()
' Version using GetEnumerator() 
Dim lines As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line)
Dim ienum As IEnumerator = lines.GetEnumerator()
While ienum.MoveNext()
    Dim id As Guid = CType(ienum.Current, ContextNode).Id
    ids.Add(id)
End While
           ArrayList ids = new ArrayList();
            // Version using GetEnumerator()
            ContextNodeCollection lines =
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
            IEnumerator ienum = lines.GetEnumerator();
            while (ienum.MoveNext())
            {
                Guid id = ((ContextNode)ienum.Current).Id;
                ids.Add(id);
            }

The following example uses the foreach statement, which calls the GetEnumerator method in internal code generated by the compiler to support the statement.

' Version using foreach 
Dim line As ContextNode
For Each line In lines
    Dim id As Guid = line.Id
    ids.Add(id)
Next line
           // Version using foreach 
            foreach (ContextNode line in lines)
            {
                Guid id = line.Id;
                ids.Add(id);
            }
