Exemplos

O exemplo seguinte demonstra como usar GetEnumerator para iterar através das chaves e valores de um Lookup<TKey,TElement>. Este exemplo de código faz parte de um exemplo maior fornecido para a Lookup<TKey,TElement> classe.

// 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())
