Sitecore以编程方式访问布局定义

的RenderingReference.RenderingItem是指在/布局部分渲染项目.你能做的就是用RenderingReference.Settings.Datasource.

所以你的代码看起来像:

foreach (var rendering in renderings)
{
    if (rendering.Placeholder == "headerPlaceholder")
        headerRenderingDatasourceId = rendering.Settings.Datasource;
    else if (rendering.Placeholder == "/aboutSectionPlaceholder/textPlaceholder")
        aboutRenderingDatasourceId = rendering.Settings.Datasource;
}

Item headerRenderingDatasourceItem;
if (!string.IsNullOrEmpty(headerRenderingDatasourceId)
    headerRenderingDatasourceItem = item.Database.GetItem(headerRenderingDatasourceId);
