План выступления
LINQ to SharePoint 2010Open Data Protocol
LINQ to SharePoint
Преимущества LINQ
Строгая типизацияЗапросы к реляционным данным в строго-типизированной формеКомпилятор проверит ошибки в запросахIntelliSense
Унифицированный путь получения данных из любого источника
LINQ to SharePoint
SPMetalГенерирует DataContextSPMetal /web:http://ContosoServer/Marketing /code:MarketingSite.cs
LINQ to SharePoint
НедостаткиПреобразуется в CAMLНе все операторы реализованыДвухэтапные запросыАггрегирующие запросыSPSiteDataQuery
Mapping
internal partial class OrganisationSiteDataContext : Microsoft.SharePoint.Linq.DataContext{}
[ContentType(Name = "Employee")]public partial class Employee{
[Column(Name="ID", IsId=true, ReadOnly=true, FieldType="Counter")] public int Id {get; set;}
}
ICostumMapping
public partial class Project : ICustomMapping{
[CustomMapping(Columns = new String[] { «Due_x0020_Date», «IsCancelled» })] public void MapFrom(object listItem) {
this.DueDate = ((SPListItem)listItem)[“Due_x0020_Date”]; this.IsCancelled = ((SPListItem)listItem)[“IsCancelled”];
} public void MapTo(object listItem) {
((SPListItem)listItem)[“Due_x0020_Date”] = this.DueDate; ((SPListItem)listItem)[“IsCancelled”] = this.IsCancelled;
} public void Resolve(RefreshMode mode, object originalListItem, object databaseObject){ }
