Public Function GetEnumerator () As IEnumerator(Of IGrouping(Of TKey, TElement))

Examples
The following example demonstrates how to use GetEnumerator to iterate through the keys and values of a Lookup<TKey,TElement>. This code example is part of a larger example provided for the Lookup<TKey,TElement> class.
// Iterate through each IGrouping in the Lookup and output the contents.
foreach (IGrouping<char, string> packageGroup in lookup)
{
// Print the key value of the IGrouping.
Console.WriteLine(packageGroup.Key);
// Iterate through each value in the IGrouping and print its value.
foreach (string str in packageGroup)
Console.WriteLine(" {0}", str);
}
Dim output As New System.Text.StringBuilder
' Iterate through each IGrouping in the Lookup and output the contents.
For Each packageGroup As IGrouping(Of Char, String) In lookup
' Print the key value of the IGrouping.
output.AppendLine(packageGroup.Key)
' Iterate through each value in the IGrouping and print its value.
For Each str As String In packageGroup
output.AppendLine(String.Format(" {0}", str))
Next
Next
' Display the output.
MsgBox(output.ToString())
