在SharePoint里设置list的 Created和Modified时间是否可以修改.

看代码:

?

private void SetListReadOnly(bool isReadOnly,String _listID, String _listVersion)

{

if (string.IsNullOrEmpty(_listID) || string.IsNullOrEmpty(_listVersion))

this.InitListInfo();

 

string updateFields =

@"<Fields>

<Method ID='1'>

<Field ID='{{28cf69c5-fa48-462a-b5cd-27b6f9d2bd5f}}' ColName='tp_Modified' RowOrdinal='0' ReadOnly='{0}' Type='DateTime' Name='Modified' DisplayName='Modified' StorageTZ='TRUE' SourceID='http://schemas.microsoft.com/sharepoint/v3' StaticName='Modified' FromBaseType='TRUE' Version='4' ShowInListSettings='FALSE' ShowInNewForm='FALSE' ShowInEditForm='FALSE' />

</Method>

<Method ID='2'>

<Field ID='{{8c06beca-0777-48f7-91c7-6da68bc07b69}}' ColName='tp_Created' RowOrdinal='0' ReadOnly='{0}' Type='DateTime' Name='Created' DisplayName='Created' StorageTZ='TRUE' SourceID='http://schemas.microsoft.com/sharepoint/v3' StaticName='Created' FromBaseType='TRUE' Version='4' ShowInListSettings='FALSE' ShowInNewForm='FALSE' ShowInEditForm='FALSE' />

</Method>

</Fields>";

updateFields = string.Format(updateFields, isReadOnly.ToString());

XmlDocument doc = new XmlDocument();

doc.LoadXml(updateFields);

 

XElement result = XElement.Parse(_ws.UpdateList(

_listID, null, null, doc.DocumentElement, null, _listVersion).OuterXml);

_listVersion =

result.Elements().Where(el => el.Name.LocalName == "ListProperties").First().Attribute("Version").Value;

}
