是否可以使用CSOM在SharePoint中创建字段,而不是使用XML?
我见过很多使用XML的例子,但没有一个只是以编程方式为字段设置属性?
fields.Add(new **FieldCreationInformation** {
InternalName = "Test",
etc..
});

这是可行的,在下面的例子中引入了FieldCreationInformation class
:
[XmlRoot("Field")]
public class FieldCreationInformation
{
[XmlAttribute("ID")]
public Guid Id { get; set; }
[XmlAttribute()]
public string DisplayName { get; set; }
[XmlAttribute("Name")]
public string InternalName { get; set; }
[XmlIgnore()]
public bool AddToDefaultView { get; set; }
//public IEnumerable<KeyValuePair<string, string>> AdditionalAttributes { get; set; }
[XmlAttribute("Type")]
public FieldType FieldType { get; set; }
[XmlAttribute()]
public string Group { get; set; }
[XmlAttribute()]
public bool Required { get; set; }
public string ToXml()
{
var serializer = new XmlSerializer(GetType());
var settings = new XmlWriterSettings();
settings.Indent = true;
settings.OmitXmlDeclaration = true;
var emptyNamepsaces = new XmlSerializerNamespaces(new[] { XmlQualifiedName.Empty });
using (var stream = new StringWriter())
using (var writer = XmlWriter.Create(stream, settings))
{
serializer.Serialize(writer, this, emptyNamepsaces);
return stream.ToString();
}
}
public FieldCreationInformation()
{
Id = Guid.NewGuid();
}
}
然后创建新字段的扩展方法:
public static class FieldCollectionExtensions
{
public static Field Add(this FieldCollection fields, FieldCreationInformation info)
{
var fieldSchema = info.ToXml();
return fields.AddFieldAsXml(fieldSchema, info.AddToDefaultView, AddFieldOptions.AddFieldToDefaultView);
}
}
<强>用法强>
var fieldInfo = new FieldCreationInformation();
fieldInfo.FieldType = FieldType.Geolocation;
fieldInfo.InternalName = "ContactsLocation";
fieldInfo.DisplayName = "Contacts Location";
ctx.Site.RootWeb.Fields.Add(fieldInfo);
ctx.ExecuteQuery();

当我使用CSOM / JSOM添加字段时,我使用FieldCollection AddFieldAsXml上的方法。这需要您构建一个包含所需字段的所有属性的xml字符串,但它可以工作。我在下面列出了相关cpde的摘录:
Microsoft.SharePoint.Client.Web web = _context.Web;
FieldCollection fields = web.Fields;
_context.Load(fields);
_context.ExecuteQuery();
Field field = fields.FirstOrDefault(f => f.StaticName == _staticName);
if (field == null)
{
Field createdField = fields.AddFieldAsXml(xml, false, AddFieldOptions.AddToNoContentType);
_context.Load(createdField);
_context.ExecuteQuery();
}
如果要将字段直接添加到现有列表,则使用类似的代码。
