sitecore - 从 Sitecore 项目中删除渲染

我必须通过渲染 id 删除渲染的所有实例。我试过下面的代码，但它不起作用。

LayoutField layoutField = new LayoutField(item.Fields[Sitecore.FieldIDs.LayoutField]);
LayoutDefinition layoutDefinition = LayoutDefinition.Parse(layoutField.Value);
DeviceDefinition deviceDefinition = layoutDefinition.GetDevice(Sitecore.Context.Device.ID.ToString());

//Create a RenderingDefinition and add the reference of sublayout or rendering
RenderingDefinition renderingDefinition = new RenderingDefinition();
renderingDefinition.ItemID = sublayoutId;

var d = layoutDefinition.GetDevice(deviceDefinition.ID.ToString());
d.Renderings.Remove(renderingDefinition);

item.Editing.BeginEdit();
layoutField.Value = layoutDefinition.ToXml();
item.Editing.EndEdit();

Programmatically removing sublayouts in Sitecore

最佳答案

试试下面的代码。我还没有测试过它，但它没有创建 RenderingDefinition 对象并将其从列表中删除(这将不起作用，因为它不是对象的同一实例)，而是过滤现有的渲染数组，比较 ItemId 属性:

LayoutField layoutField = new LayoutField(item.Fields[Sitecore.FieldIDs.LayoutField]);
LayoutDefinition layoutDefinition = LayoutDefinition.Parse(layoutField.Value);
DeviceDefinition deviceDefinition = layoutDefinition.GetDevice(Sitecore.Context.Device.ID.ToString());

var d = layoutDefinition.GetDevice(deviceDefinition.ID.ToString());

IEnumerable<RenderingDefinition> renderingsArray = d.Renderings.ToArray().Cast<RenderingDefinition>();
d.Renderings = new ArrayList(renderingsArray.Where(r => r.ItemID != sublayoutId).ToList());

item.Editing.BeginEdit();
layoutField.Value = layoutDefinition.ToXml();
item.Editing.EndEdit();
