BrowseWithPaging

Browse 只返回 References 列表, 丢弃 ContinuationPoint, 适合"已知小节点"场景. 大节点 (子节点 100+) 用 BrowseWithPaging 显式拿到 BrowsePage.

前置阅读

• 续翻分页用 BrowseNext.

签名

public BrowsePage BrowseWithPaging(string nodeId, NodeClass filter = NodeClass.Unspecified);

用法

var page = ua.BrowseWithPaging("ns=2;s=BigFolder");
Console.WriteLine($"Got {page.References.Count} children, more = {page.ContinuationPoint != null}");

if (page.ContinuationPoint != null)
{
    var next = ua.BrowseNext(page.ContinuationPoint);
    Console.WriteLine($"Next page: {next.References.Count} more children");
}

何时用 Browse vs BrowseWithPaging

场景	API
已知节点子数 ≤ 50, 不关心分页	Browse(...)
不确定子数, 安全起见	BrowseWithPaging(...) + 循环 BrowseNext
100+ 子节点的大节点	BrowseWithPaging(...) 必选
一次 Browse 多个节点	BrowseMany(...) (注意当前 BrowseMany 不返回 ContinuationPoint)

public static List<OpcUaReference> BrowseAll(
    DarraOpcUa ua,
    string nodeId,
    NodeClass filter = NodeClass.Unspecified)
{
    var all = new List<OpcUaReference>();
    var page = ua.BrowseWithPaging(nodeId, filter);
    all.AddRange(page.References);
    while (page.ContinuationPoint != null)
    {
        page = ua.BrowseNext(page.ContinuationPoint);
        all.AddRange(page.References);
    }
    return all;
}
