'Usage
Dim instance As EntitySet(Of TEntity)
[DataContractAttribute]
public sealed class EntitySet<TEntity> : IList<TEntity>,

IEnumerable<TEntity>, IOrderedQueryable, IQueryable, IList, ICollection,
IEnumerable, ICloneable
where TEntity : class
Type Parameters
- TEntity
The type of the member of the collection.
Remarks
For example, suppose a Team Members list has an Assigned Projects column that is a lookup field to a Projects list. More than one team member can be assigned to a particular project and a particular team member can be assigned to more than one project; so this is a many-to-many relationship.
Examples
The following code shows how the AssignedProjects property in the scenario described above would be declared as an EntitySet<TEntity> type that wraps a private EntitySet<TEntity> field:
[ContentType(Name="Item", Id="0x01", List="Team Members")]
[DataContract()]
public partial class TeamMembersItem : Item {
[DataMember()]
private EntitySet<Project> _projects;
public TeamMembersItem() {
this._manager = new EntitySet<Project>();
this.Initialize();
}
[Association(Name="AssignedProjects", Storage="_projects ", MultivalueType=AssociationType.Multi, List="Projects")]
public EntitySet<Project> AssignedProjects {
get {
return this._projects;
}
set {
this._projects.Assign(value);
}
}
// Other members omitted for readability.
}
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
