Lists.UpdateListItems 方法 (websvcLists)

Windows SharePoint Services 3

Adds, deletes, or updates the specified items in a list on the current site.

命名空间: websvcLists
程序集: STSSOAP （在 stssoap.dll 中）

[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
)

参数

listName: A string that contains the name of the list. It is recommended that you use the list GUID surrounded by curly braces (i.e., "{GUID}"), but you can also use the list display name.

updates

A Batch element that contains one or more methods for adding, modifying, or deleting items and that can be assigned to a System.Xml.XmlNode object.

The following example shows how to modify column values for two specified items.

XML

<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>

An empty ViewName attribute in the Batch element causes the default view to be used. The ID attribute in each Method element uniquely identifies the specific update so that errors and return values can be properly identified. Each method that is posted contains Field elements that specify the ID of the item and the new field value for the item. The field ID does not correspond to the index of the item in the collection of items for the list.

The following example shows the format for adding a new item that contains both a Date value and a DateTime value.

XML

<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>

The following example shows how to delete two items.

XML

<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>

注意：
IDs for deleted items are maintained after delete operations. Consequently, the example deletes the second and eighth items in the list, but 2 and 8 are not reassigned as the IDs of other items.

For descriptions of the various formats used for field types that can be passed in this parameter see SPListItem.

The following examples show the methods that can be posted for operations related to document libraries:

返回值

An XMLDATA fragment in the following form that shows the status of each method block posted through the updates parameter and that can be assigned to a System.Xml.XmlNode object. For items successfully updated, a row fragment is returned with the updated row values.

XML

<Results xmlns="http://schemas.microsoft.com/sharepoint/soap/">

         xmlns:z="#RowsetSchema" />
   </Result>
   ...
</Results>

In this example, the ows_Author and ows_Editor attributes pertain to lookup fields to another list in the database, representing the integer IDs of items in the UserInfo table and the actual values contained by these items within the table.

示例

The following code example modifies the values of two different field values within two items in a list on the current site. The example uses an XmlDocument object to create XmlNode objects for parameters.

This example requires that a using (Visual C#) or Imports (Visual Basic) directive be included for the System.Xml namespace.

C#

VB

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);
