迭代共享点列表

在代码中如何访问列表，例如共享点中的“MyList”， 然后迭代此列表项并获取该列表上特定列的值，例如“URL”列？

要从列表中检索所有项目并迭代每个项目，最佳解决方案如下（假设此代码作为功能的一部分运行）：

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    using(SPSite site = properties.Feature.Parent as SPSite)
    {
        SPList list = site.RootWeb.Lists["ListName"];
        SPListItemCollection items = list.Items;

        foreach (SPListItem listItem in items)
        {
            Response.Write(SPEncode.HtmlEncode(listItem["Url"].ToString()) +"<BR>");
        }
    }
}

但如果列表非常大，最好对列表项进行分页：

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    using(SPSite site = properties.Feature.Parent as SPSite)
    {
        SPList list = site.RootWeb.Lists["ListName"];

        if(items.ItemCount > 100)
        {        
            SPQuery query = new SPQuery();
            query.RowLimit = 100;
            int index = 1;

            do
            {
                SPListItemCollection items = list.GetItems(query);

                foreach (SPListItem listItem in items)
                {
                    Response.Write(SPEncode.HtmlEncode(listItem["Url"].ToString()) +"<BR>");
                }

                query.ListItemCollectionPosition = items.ListItemCollectionPosition;
                index++;

            } while (query.ListItemCollectionPosition != null);
        }
        else
        {
            SPListItemCollection items = list.Items;

            foreach (SPListItem listItem in items)
            {
                Response.Write(SPEncode.HtmlEncode(listItem["Url"].ToString()) +"<BR>");
            }
        }
    }
}
