public:
 virtual System::Collections::Generic::IEnumerator<System::Linq::IGrouping<TKey, TElement> ^> ^ GetEnumerator();

public System.Collections.Generic.IEnumerator<System.Linq.IGrouping<TKey,TElement>> GetEnumerator ();

abstract member GetEnumerator : unit -> System.Collections.Generic.IEnumerator<System.Linq.IGrouping<'Key, 'Element>>
override this.GetEnumerator : unit -> System.Collections.Generic.IEnumerator<System.Linq.IGrouping<'Key, 'Element>>

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

반환

IEnumerator<IGrouping<TKey,TElement>>

예제

다음 예제에서는 를 사용하여 GetEnumerator 의 Lookup<TKey,TElement>키와 값을 반복하는 방법을 보여 줍니다. 이 코드 예제는에 대해 제공 된 큰 예제의 일부는 Lookup<TKey,TElement> 클래스입니다.

// 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())
