ContextNodeCollection.GetEnumerator Method
Returns an object that both implements the IEnumerator interface, and iterates through the ContextNode objects within the ContextNodeCollection.
Namespace: System.Windows.Ink
Assembly: IAWinFX (in IAWinFX.dll)
Syntax
'Declaration
Public Function GetEnumerator As ContextNodeCollection.ContextNodeCollectionEnumerator
'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: System.Windows.Ink.ContextNodeCollection.ContextNodeCollectionEnumerator
An object that both implements the IEnumerator interface, and iterates through the ContextNode objects within the ContextNodeCollection.
Examples
The examples in this section show two ways to iterate through a ContextNodeCollection, getting the identifiers for each of the lines in an InkAnalyzer named theInkAnalyzer.
The following example gets the IEnumerator for the ContextNodeCollection (named lines).
Dim ids As New ArrayList()
' Version using GetEnumerator()
Dim lines As ContextNodeCollection = theInkAnalyzer.FindNodesOfType(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(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 (contained 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);
}
