如何为DataGrid WPF绑定NameValueCollection？

NameValueCollection collection = new NameValueCollection();
collection.Add("Key1", "Value1");
collection.Add("Key2", "Value2");
// 添加更多的键值对...

<DataGrid x:Name="dataGrid" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Key" Binding="{Binding Key}" />
        <DataGridTextColumn Header="Value" Binding="{Binding Value}" />
    </DataGrid.Columns>
</DataGrid>

ObservableCollection<KeyValuePair<string, string>> observableCollection = new ObservableCollection<KeyValuePair<string, string>>();
foreach (string key in collection.AllKeys)
{
    observableCollection.Add(new KeyValuePair<string, string>(key, collection[key]));
}
dataGrid.ItemsSource = observableCollection;
