Beispiele

Das folgende Beispiel zeigt, wie die Remove Methode implementiert wird. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die IDictionary Klasse bereitgestellt wird.

public void Remove(object key)
{
    if (key == null) throw new ArgumentNullException("key");
    // Try to find the key in the DictionaryEntry array
    Int32 index;
    if (TryGetIndexOfKey(key, out index))
    {
        // If the key is found, slide all the items up.
        Array.Copy(items, index + 1, items, index, ItemsInUse - index - 1);
        ItemsInUse--;
    }
    else
    {
        // If the key is not in the dictionary, just return.
    }
}

Public Sub Remove(ByVal key As Object) Implements IDictionary.Remove
    If key = Nothing Then
        Throw New ArgumentNullException("key")
    End If
    ' Try to find the key in the DictionaryEntry array
    Dim index As Integer
    If TryGetIndexOfKey(key, index) Then

        ' If the key is found, slide all the items up.
        Array.Copy(items, index + 1, items, index, (ItemsInUse - index) - 1)
        ItemsInUse = ItemsInUse - 1
    Else

        ' If the key is not in the dictionary, just return. 
    End If
End Sub
