性能：提高具有相同DisplayMemberPath和SelectedValuePath的多個組合框綁定性能的最佳方法是什么

Question

我在WPF應用程序中有5個組合框。

下面是綁定所有組合框的代碼

private void BindYears()
{
        cbBeginYear.ItemsSource = listOfYears;
        cbBeginYear.DisplayMemberPath = "YearID";
        cbBeginYear.SelectedValuePath = "YearID";

        cbEnd_Year.ItemsSource = listOfYears;
        cbEnd_Year.DisplayMemberPath = "YearID";
        cbEnd_Year.SelectedValuePath = "YearID";

        cbExactYear.ItemsSource = listOfYears;
        cbExactYear.DisplayMemberPath = "YearID";
        cbExactYear.SelectedValuePath = "YearID";

        cbStart_Year.ItemsSource = listOfYears;
        cbStart_Year.DisplayMemberPath = "YearID";
        cbStart_Year.SelectedValuePath = "YearID";

        cbEndYear.ItemsSource = listOfYears;
        cbEndYear.DisplayMemberPath = "YearID";
        cbEndYear.SelectedValuePath = "YearID";
}

我可以用這種方式做同樣的事情嗎，下面的這種方法將有助於提高任何一種性能。

private void BindYears()
{
            cbEndYear.ItemsSource = cbStart_Year.ItemsSource = cbExactYear.ItemsSource = cbEnd_Year.ItemsSource = cbBeginYear.ItemsSource = listOfYears;
            cbEndYear.DisplayMemberPath = cbStart_Year.DisplayMemberPath = cbExactYear.DisplayMemberPath = cbEnd_Year.DisplayMemberPath = cbBeginYear.DisplayMemberPath = "YearID";
            cbEndYear.SelectedValuePath = cbStart_Year.SelectedValuePath = cbExactYear.SelectedValuePath = cbEnd_Year.SelectedValuePath = cbBeginYear.SelectedValuePath = "YearID";
}

Answer 1

根據您的評論，我可能會這樣：

private void BindYears(Combobox box)
{
    box.ItemsSource = listOfYears;
    box.DisplayMemberPath = "YearID";
    box.SelectedValuePath = "YearID";
}

private void BindBoxes()
{
    BindYears(cbBeginYear);
    BindYears(cbEnd_Year);
    BindYears(cbExactYear);
    BindYears(cbStart_Year);
    BindYears(cbEndYear);
}
