Question

我正在尝试使用Copy.asmx webservice，CopyIntoItems方法从本地计算机上传文档。我可以成功上传文档和DateTime属性，但我无法更新文档库的查找属性。我正在使用带有sp2的MOSS 2007

我使用的代码如下所示：

string[] destinationUrls = { Uri.EscapeUriString(destinationUrl) };

CopySharepointService.FieldInformation dateInformation = new CopySharepointService.FieldInformation();
dateInformation.DisplayName = "Date";
dateInformation.Type = CopySharepointService.FieldType.DateTime;
dateInformation.Value = DateTime.Today.ToString();

CopySharepointService.FieldInformation fundInformation = new CopySharepointService.FieldInformation();
fundInformation.DisplayName = "Fund";
fundInformation.Type = CopySharepointService.FieldType.Lookup;
fundInformation.Id = new Guid(fundGuidItem); // This is the GUID of the field being updated in the document library
fundInformation.Value = "1";

CopySharepointService.FieldInformation[] info = { dateInformation, fundInformation };            
CopySharepointService.CopyResult[] result;    
CopySharepointService.CopySoapClient CopyService2007 = new CopySoapClient("CopySoap");

CopyService2007.ClientCredentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
CopyService2007.CopyIntoItems(destinationUrl, destinationUrls, info, fileData, out result);

文档已成功上传，但查找字段未更新

有人可以帮忙吗？

Answer 1

我刚发现这个帖子：

“不幸的是，CopyIntoItems不会将信息放入”File“，”Computed“或”Lookup“类型的字段中.Web服务使用SPCopy类的CopyIntoItem，它调用一个名为FieldShouldBeCopiedTo的私有方法。此方法包含修复Lookup字段的逻辑被复制。“

我有时讨厌SharePoint。

无法做到这一点;唯一的选择是重新连接，获取列表项本身并以这种方式更新元数据。请记住：查找字段需要使用number;#的格式 - 所以，如果您是，那么数据是否为：

12;#Some Option

在Xml批量更新中使用12;#。

不幸的是，您必须通过UpdateListItems跟进来设置所有“有趣”的元数据。

来自链接中的示例：

Web_Reference_Folder.Lists listService = new Web_Reference_Folder.Lists();
listService.Credentials= System.Net.CredentialCache.DefaultCredentials;

string strBatch = "<Method ID='1' Cmd='Update'>" + 
    "<Field Name='ID'>4</Field>" +
    "<Field Name='Field_Number'>999</Field></Method>" +
    "<Method ID='2' Cmd='Update'><Field Name='ID' >6</Field>" +
    "<Field Name='Field_DateTime'>
        2003-11-11T09:15:30Z</Field></Method>"; 

XmlDocument xmlDoc = new System.Xml.XmlDocument();

System.Xml.XmlElement elBatch = xmlDoc.CreateElement("Batch");

elBatch.SetAttribute("OnError","Continue");
elBatch.SetAttribute("ListVersion","1");
elBatch.SetAttribute("ViewName",
    "0d7fcacd-1d7c-45bc-bcfc-6d7f7d2eeb40");

elBatch.InnerXml = strBatch;

XmlNode ndReturn = listService.UpdateListItems("List_Name", elBatch);

MessageBox.Show(ndReturn.OuterXml);

使用CopyIntoItems上传文档时无法更新查找字段
