c# – 如何使用Sharepoint Web Service从.NET获取文档列表?

技术: Winforms,.NET,C#,Sharepoint Web Services

我正在编写一个winform桌面应用程序,该应用程序应该访问一个特定的Sharepoint文档列表和自定义输入变量(从Sharepoint文档库)

http://www.infoq.com/articles/swanson-moss-web-services

这个网站给了我很好的了解哪些网络服务是可用的,但是我无法从中了解如何访问我想要的内容.

使用website.com/_vti_bin/Lists.asmx和website.com/_vti_bin/Dws.asmx作为我的网络引用.

com.website.Lists splist = new Project.com.website.Lists();
com.website1.Dws spData = new Project.com.website1.Dws();

splist.Credentials = new NetworkCredential("username", "password", "domain");
splist.GetList("My_list");

这是我第一次尝试连接,它给了我一个SOAPException(这是我可以给出的细节的程度)

不知道是否需要这样做,但是还有更多的一个sharepoint网站托管在“website.com”(我正在尝试访问的一个是“website.com/sites/mysite”)这是否改变了事情?

我只是试图找出我是否正在使用这项服务的轨道上,或者如果我错了

编辑1:发掘原始问题,让人们了解发生了什么.

@CBono:您链接的文章是开始入门的一个很好的帮助. (我不能upvote …()我已经设法得到列表,但格式化,或获取AT数据证明是困难的.
以下是提供的内容:

query.InnerXml = "<Where><Gt><FieldRef Name=\"ID\" />" + "<Value Type=\"Counter\">3</Value></Gt></Where>";
viewFields.InnerXml = "<FieldRef Name=\"Title\" />"; 
queryOptions.InnerXml = "";

但我的结果如下所示:

我有nooooooo的想法,我如何使用CAML打破这一点. (另外,我使用的是Sharepoint Server 2007,而不是2010

Not sure if this is needed, but there
are more that one sharepoint sites
hosted at “website.com” (The one I’m
trying to access is
“website.com/sites/mysite” ) Does that
change things?

绝对是!您发现的Web服务URL实际上是虚拟的,这意味着每个SharePoint站点下的URL模式_vti_bin / Lists.asmx都可用.无论您的列表所在的网站是您的Web服务网址的起点.

因此,请尝试:http://website.com/sites/mysite/_vti_bin/Lists.asmx

您也可能会发现MSDN的SharePoint Web Service Guidelines文章也有帮助.

更新#1:

CAML不会帮助你“分开”你的结果.它是一个严格的查询/过滤技术,它看起来像你正在使用它.告诉我们您要恢复的结果是否符合您的期望.如果您需要帮助构建更复杂的CAML查询,建议您下载U2U’s CAML Query Builder的副本(但这是另一个主题).

所以,对结果.看看它有点混乱,但有一些疯狂的方法.您在列表中设置的列全部在这里(如果您不是在CAML查询中约束它们,这是可能的).您会注意到它们使用SharePoint的内部名称作为列,前缀为ows_.因此,如果您知道内部名称,则可以构造XML属性名称,并使用XML类,LINQ或XSLT来深入了解结果并获取所需内容.见my answer to another SO question for tips on divining SP’s internal column names.

如果这有助于知道我在这种情况下所做的工作,我只需要构建一个POCO模型类来表示我的一个列表项,然后编写一个解析器方法来获取SharePoint的XML结果并返回模型对象的集合.我很喜欢LINQ to XML这个任务.

您是否使用SharePoint 2010,您可以使用新的Client Object Model classes,并在SharePoint站点,列表,列表项等中使用更好的托管包装器.

更新#2:

只是为了一些颜色,我发布了我用来解析SharePoint XML的代码示例.此示例中的注册人员是我写的一个POCO模型类,用于表示自定义列表的SharePoint列表项.这是微不足道的,我不会打扰张贴它.

/// <summary>
/// Parses registrant XML returned from SharePoint's Lists web service into a collection 
/// of <see cref="Registrant"/> objects (root element = "listitems").
/// </summary>
/// <param name="xml">SharePoint XML</param>
/// <returns>Collection of Registrant objects, or null if no registrant data could be parsed.</returns>
public static List<Registrant> ParseSharePointXmlCollection( XElement xml ) {

  // Test: Not expected XML element or has no child elements
  if ( !xml.Name.LocalName.Equals( "listitems" ) || !xml.HasElements ) {
    return null;
  }

  List<Registrant> regList = null;

  XElement data = xml.Element( XName.Get( "data", "urn:schemas-microsoft-com:rowset" ) );
  if ( (data != null) && (data.HasElements) ) {

    regList = new List<Registrant>();

    IEnumerable<XElement> regXmlNodes = data.Elements( XName.Get( "row", "#RowsetSchema" ) );
    foreach (XElement regXml in regXmlNodes) {
      Registrant reg = ParseSharePointXml( regXml );
      if ( reg != null ) {
        regList.Add( reg );
      }
    }
  }

  return regList;
}

/// <summary>

/// <see cref="Registrant"/> object (root element = "row").
/// </summary>
/// <param name="xml">SharePoint XML</param>
/// <returns>A Registrant object, or null if no registrant data could be parsed.</returns>
public static Registrant ParseSharePointXml( XElement xml ) {

  // Test: Not expected XML element or has no attributes
  if ( !xml.Name.LocalName.Equals( "row" ) || !xml.HasAttributes ) {
    return null;
  }

  Registrant reg = null;

  // Parse ID (if this fails, fail the whole operation)
  if ( xml.Attribute( "ows_ID" ) != null ) {
    reg = new Registrant();
    reg.ID = xml.Attribute( "ows_ID" ).Value;
  }
  else {
    return null;
  }

  // Parse First Name
  if ( xml.Attribute( "ows_Q_Registrant_x0020_First_x0020_N" ) != null ) {
    reg.FirstName = xml.Attribute( "ows_Q_Registrant_x0020_First_x0020_N" ).Value;
  }

  // Parse Last Name
  if ( xml.Attribute( "ows_Q_Registrant_x0020_Last_x0020_Na" ) != null ) {
    reg.LastName = xml.Attribute( "ows_Q_Registrant_x0020_Last_x0020_Na" ).Value;
  }

  // Parse Email
  if ( xml.Attribute( "ows_Q_Registrant_x0020_Email" ) != null ) {
    reg.Email = xml.Attribute( "ows_Q_Registrant_x0020_Email" ).Value;
  }

  // Parse Assistant Name
  if ( xml.Attribute( "ows_Q_Asst_x0020_First_x0020_Name" ) != null ) {
    reg.AssistantFirstName = xml.Attribute( "ows_Q_Asst_x0020_First_x0020_Name" ).Value;
  }
  if ( xml.Attribute( "ows_Q_Asst_x0020_Name" ) != null ) {
    reg.AssistantLastName = xml.Attribute( "ows_Q_Asst_x0020_Name" ).Value;

    reg.AssistantEmail = xml.Attribute( "ows_Q_Asst_x0020_Email" ).Value;
  }

  return reg;
}

更新#3:

将XmlNode对象转换为XElement的示例代码:

public static XElement GetXElement( this XmlNode node ) {
  XDocument xdoc = new XDocument();
  using ( XmlWriter xmlWriter = xdoc.CreateWriter() ) {
    node.WriteTo( xmlWriter );
  }
  return xdoc.Root;
}
