我想使用 c# 将共享点列表的选择列中的 MultipleCheckbox 项目绑定到 asp.net CheckBoxListItem。我正在使用 XELEMENT 检索 List 的信息：

在 .cs 文件中：

XElement listStructure;

listStructure = proxy.GetList("WebsiteSubscriber");

这里将 XML 设置为：

  <List DocTemplateUrl="" DefaultViewUrl="/Lists/WebsiteSubscriber/AllItems.aspx" MobileDefaultViewUrl="" ID="{2C8A80EA-38C5-48F7-9D7D-400D445A5E64}" Title="WebsiteSubscriber" Description="" ImageUrl="/_layouts/images/itgen.png" Name="{2C8A80EA-38C5-48F7-9D7D-400D445A5E64}" BaseType="0" FeatureId="00bfea71-de22-43b2-a848-c05709900100" ServerTemplate="100" Created="20130417 02:18:11" Modified="20130424 09:27:11" LastDeleted="20130419 04:46:25" Version="5" Direction="none" ThumbnailSize="" WebImageWidth="" WebImageHeight="" Flags="545263616" ItemCount="13" AnonymousPermMask="0" RootFolder="/Lists/WebsiteSubscriber" ReadSecurity="1" WriteSecurity="1" Author="8" EventSinkAssembly="" EventSinkClass="" EventSinkData="" EmailAlias="" WebFullUrl="/" WebId="198e057a-38e8-410a-8358-ed95f77d18ea" SendToLocation="" ScopeId="e2cbf2fd-93e4-408d-bd4e-320321734b8c" MajorVersionLimit="0" MajorWithMinorVersionsLimit="0" WorkFlowId="" HasUniqueScopes="False" NoThrottleListOperations="False" HasRelatedLists="" AllowDeletion="True" AllowMultiResponses="False" EnableAttachments="True" EnableModeration="False" EnableVersioning="False" HasExternalDataSource="False" Hidden="False" MultipleDataList="False" Ordered="False" ShowUser="True" EnablePeopleSelector="False" EnableResourceSelector="False" EnableMinorVersion="False" RequireCheckout="False" ThrottleListOperations="False" ExcludeFromOfflineClient="False" EnableFolderCreation="False" IrmEnabled="False" IsApplicationList="False" PreserveEmptyValues="False" StrictTypeCoercion="False" EnforceDataValidation="False" MaxItemsPerThrottledOperation="100000" xmlns="http://schemas.microsoft.com/sharepoint/soap/">

我想从 XML 获得以上值。

<CHOICES>
            <CHOICE>Articles</CHOICE>
            <CHOICE>Websites</CHOICE>
            <CHOICE>Books</CHOICE>
  </CHOICES>

如果你修复了你的 XML，这就是你想要的：

var choices = (from n in xml.Descendants()
              where n.Name.LocalName == "CHOICES"
              select new
              {
                    CHOICES = n.Elements().Select(x => x.Value).ToList()
              }).ToList();

将为您提供CHOICES包含您的CHOICE元素值的匿名类型元素的列表。示例输出：

看评论：

var choices = (from n in xml.Descendants()
               where n.Name.LocalName == "CHOICE"
               select n.Value).ToList();

这将返回以下字符串值的列表：

  • 文章
  • 网站
  • 图书
  • 0;#批准
  • 1;#拒绝
  • 2;#待定
  • 3;#草稿
  • 4;#预定
