能否批量将指定内容类型的所有内容项添加至2sxc列表？

Great question—manually adding dozens or hundreds of content items to a 2sxc List is a total time-suck, so let’s break down the most efficient ways to handle this in bulk:

1. Use the 2sxc Admin UI (Quick & No-Code) #

If you’re working within the same DNN/2sxc instance, the built-in bulk selection tool is your first go-to:

• Open your 2sxc List module’s management interface, then navigate to the Items tab
• Look for the Add Existing button (usually in the top toolbar)
• In the content picker modal, use the dropdown filter to select your target content type
• Batch-select items: Use Ctrl+Click (Windows) or Cmd+Click (Mac) to pick multiple items, or check the top checkbox to select all items in the filtered list
• Hit Add Selected—done! No more tedious one-by-one clicks.

2. Use a Razor Script (For Large Datasets or Automation) #

If you have hundreds/thousands of items (and the UI starts lagging), a quick Razor script will handle this in seconds. Here’s a template you can adapt:

// Replace with your source content type name
var sourceContentType = "YourSourceContentType";
// Replace with your List's content type name
var listContentType = "YourListContentType";
// Replace with the field name in your List that references the source items
var referenceFieldName = "RelatedSourceItem";

// Get all source items
var sourceItems = App.Data[sourceContentType].ToList();

// Loop through and add each to the List (as a reference, not a copy)
foreach (var item in sourceItems)
{
    // Create a new List item linked to the source content
    App.Data.Create(listContentType, new {
        // Map required fields - adjust these to match your List's fields
        Title = item.Title,
        [referenceFieldName] = item.EntityId
    });
}

// Optional: Confirm completion
<p>Successfully added @sourceItems.Count items to the List!</p>

How to use this: #

• Create a new 2sxc App or use an existing one, then add a new Razor view
• Paste the code, replace the placeholder values with your actual content type/field names
• View the page once to run the script (it will execute immediately)
• Important: Delete or disable the view after running to avoid accidentally duplicating items

Critical Notes Before You Start #

• Backup your data first: Bulk operations can go wrong—take a DNN content backup before proceeding
• If your List uses copies of content (not references), adjust the script to copy field values instead of linking EntityIds
• For extremely large datasets (10k+ items), add a batch loop with small delays to avoid timeouts
