概述

在sharepoint 项目中，后期做数据迁移时，会用到sharepoint的web service来完成把数据导入sharepoint站点的功能。

web service 名称：

http://[site]/_vti_bin/Lists.asmx

我们用它来新增，修改或者删除当前站点特定list 的item操作。

调用的方法：

[SoapDocumentMethodAttribute("http://schemas.microsoft.com/sharepoint/soap/UpdateListItems", RequestNamespace="http://schemas.microsoft.com/sharepoint/soap/", ResponseNamespace="http://schemas.microsoft.com/sharepoint/soap/", Use=SoapBindingUse.Literal, ParameterStyle=SoapParameterStyle.Wrapped)]
public XmlNode UpdateListItems (string listName,XmlNode updates
)

listName:当前站点list的名字。

操作list的item则通过XmlNode来完成。

更改普通list里item对应field Name的xml代码：

<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2"><Method ID="1" Cmd="Update"><Field Name="ID">4<Field><Field Name="Field_Name">Value</Field></Method><Method ID="2" Cmd="Update"><Field Name="ID" >6</Field><Field Name="Field_Name">Value</Field></Method>
</Batch>

新增list里item的xml代码:

<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2"><Method ID="1" Cmd="New"><Field Name='ID'>New</Field><Field Name="Title">Value</Field><Field Name="Date_Column">2007-3-25</Field><Field Name="Date_Time_Column">2006-1-11T09:15:30Z</Field></Method>
</Batch>

删除list里item的xml代码:

<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2"><Method ID="1" Cmd="Delete"><Field Name='ID'>2</Field></Method><Method ID="2" Cmd="Delete"><Field Name='ID'>8</Field></Method>
</Batch>

document libraries操作:

新建文件夹xml的代码:

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}"><Method ID="1" Cmd="New"><Field Name="ID">New</Field><Field Name="FSObjType">1</Field><Field Name="BaseName">Name</Field></Method>
</Batch>

更新文件夹的xml代码：

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}"><Method ID="1" Cmd="Update"><Field Name="ID">3</Field><Field Name="owshiddenversion">1</Field><Field Name="FileRef">http://Server/[sites/][Site/]Shared Documents/Folder</Field><Field Name="FSObjType">1</Field><Field Name="BaseName">Name</Field></Method>
</Batch>

删除文件夹xml代码:

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}"><Method ID="1" Cmd="Delete"><Field Name="ID">4</Field><Field Name="FileRef">http://Server/[sites/][Site/]Shared Documents/Folder</Field></Method>
</Batch>

更新文件夹里文件的xml代码：

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}"><Method ID="1" Cmd="Update"><Field Name="ID">2</Field><Field Name="owshiddenversion">1</Field><Field Name="FileRef">http://Server/[sites/][Site/]Shared Documents/File</Field><Field Name="BaseName">Name</Field></Method>
</Batch>

删除文件夹里文件的xml代码:

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}"><Method ID="1" Cmd="Delete"><Field Name="ID">3</Field><Field Name="FileRef">http://Server/[sites/][Site/]Shared Documents/File</Field></Method>
</Batch>

调用方法：

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);

返回XmlNode代码的格式：

<Results xmlns="http://schemas.microsoft.com/sharepoint/soap/"><Result ID="1,Update"><ErrorCode>0x00000000</ErrorCode><z:row ows_ID="4" ows_Title="Title" ows_Modified="2003-06-19 20:31:21" ows_Created="2003-06-18 10:15:58" ows_Author="3;#User1_Display_Name" ows_Editor="7;#User2_Display_Name" ows_owshiddenversion="3" ows_Attachments="-1" ows__ModerationStatus="0" ows_LinkTitleNoMenu="Title" ows_LinkTitle="Title" ows_SelectTitle="4" ows_Order="400.000000000000" ows_GUID="{4962F024-BBA5-4A0B-9EC1-641B731ABFED}" ows_DateColumn="2003-09-04 00:00:00" ows_NumberColumn="791.00000000000000" xmlns:z="#RowsetSchema" /></Result><Result ID="2,Update"><ErrorCode>0x00000000</ErrorCode><z:row ows_ID="6" ows_Title="Title" ows_Modified="2003-06-19 20:31:22" ows_Created="2003-06-18 19:07:14" ows_Author="2;#User1_Display_Name" ows_Editor="6;#User2_Display_Name" ows_owshiddenversion="4" ows_Attachments="0" ows__ModerationStatus="0" ows_LinkTitleNoMenu="Title" ows_LinkTitle="Title" ows_SelectTitle="6" ows_Order="600.000000000000" ows_GUID="{2E8D2505-98FD-4E3E-BFDA-0C3DEBE483F7}" ows_DateColumn="2003-06-23 00:00:00" ows_NumberColumn="9001.00000000000000" xmlns:z="#RowsetSchema" /></Result>...
</Results>

取返回值的方法:

            foreach (XmlNode node in nodes){if (node.Name == "rs:data"){for (int i = 0; i < node.ChildNodes.Count; i++){if (node.ChildNodes[i].Name == "z:row"){string ID = node.ChildNodes[i].Attributes["ows_ID"].Value;string Title = node.ChildNodes[i].Attributes["ows_Title"].Value;}}}}
