这是我的 ListBoxItem 在具有自定义模板的 ListBox 中的示例：

<ListBox Margin="0,140,0,0" x:Name="ListBox_Main" VerticalAlignment="Top" Foreground="Black" SelectionChanged="ListBox_Main_SelectionChanged" FontFamily="Segoe UI" Grid.RowSpan="2" FontSize="26.667">
            <ListBox.Resources>

            </ListBox.Style>
                <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <StackPanel Orientation="Vertical" />                                     
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
        <ListBox.ItemContainerStyle>
            <Style TargetType="ListBoxItem">
                <Setter Property="Padding" Value="120 10 120 10 " />
            </Style>
        </ListBox.ItemContainerStyle>
            <ListBoxItem Background="#19000000" Template="{StaticResource CustomStyle_ListBoxItem}" Content="Item 1"/>
            <ListBoxItem Background="#19000000" Template="{StaticResource CustomStyle_ListBoxItem}" Content="Item 2"/>
            <ListBoxItem Background="#19000000" Template="{StaticResource CustomStyle_ListBoxItem}" Content="Item 3"/>
            <ListBoxItem Background="#19000000" Template="{StaticResource CustomStyle_ListBoxItem}" Content="Item 4"/>
        </ListBox>

现在我想在 C# 中添加另一个 ListBoxItem：

ListBoxItem item = new ListBoxItem();
item.Content = "item 5";
ListBox_Main.add(item); //credit goes to Danilo Vulović

现在我想使用 {StaticResource CustomStyle_ListBoxItem} 这是我的 ListBoxItems 在 XAML 中使用的模板，我该如何在 C# 中执行此操作？

如果您总是使用相同的模板，则不必为每个项目设置模板，只需为此使用 ItemTemplate 属性！

 <ListBox ItemTemplate="{StaticResource }" x:Name="ListBox_Main" ... >

如果由于某种原因您更喜欢专门为后面代码中的每个项目执行此操作：

ListBoxItem item = new ListBoxItem();
item.Content = "item 5";
item.Template = Resources["CustomStyle_ListBoxItem"] as ControlTemplate;
ListBox_Main.Items.Add(item);
