备注

The organization service context class maintains state on the client between interactions with the Microsoft Dynamics CRM Web service to support features such as change management. This class also manages identities and tracks changes to Microsoft Dynamics CRM data. The organization service context class implements the IQueryable interface and a .NET 语言集成查询 (LINQ) query provider so you can write LINQ queries against Microsoft Dynamics CRM data.

Objects tracked by the organization service context are instances of entity types that represent data in Microsoft Dynamics CRM. You can designate actions to be performed on these objects and the service context tracks the changes. When the SaveChanges method is called, the service context instructs Microsoft Dynamics CRM to generate commands to create, update or delete the entities the tracked objects represent.

The code generation tool (CrmSvcUtil.exe) can be used to create a custom instance of the OrganizationServiceContext class. This class includes customizations and provides helper properties and methods for working with entities.

Several enumerations are used with the OrganizationServiceContext class. The MergeOption enumeration indicates how changes are applied to Microsoft Dynamics CRM data. The SaveChangesOptions enumeration determines how changes are managed by the service context if an error occurs.
