c# - MS Dynamics CRM 2011 SDK - 使用后期绑定(bind)更新实体记录

Question

有谁知道如何使用 Dynamics CRM 2011 SDK 将更改保存到后期绑定(bind)实体？

这是我试过的:

// retrieve and modify a pet...
// (This part works)
Guid findId = new Guid("6CA57D73-30CC-E111-B155-00505630052F");
ColumnSet attributes = new ColumnSet(new string[] { "name", "foodtype" });

// try to retrieve
// (this also works)
pet = xrm.Retrieve("pet", findId, attributes);
if( pet!=null )
{
    Console.WriteLine( String.Format( "Retrieved pet {0} successfully!", pet["name"].ToString() ));
    // update attributes
    pet["foodtype"] = "Seaweed";
    // (from here doesn't seem to work)
    // save pet
    xrm.SaveChanges();
    Console.WriteLine( "Done!" );
}

感谢所有帮助:)

Answer 1

试试这个:

pet["foodtype"] = "Seaweed";

xrm.UpdateObject( pet );
xrm.SaveChanges();

编辑:"The context is not currently tracking the 'pet' entity" 表示您从 Retrieve 获取的对象未附加到服务上下文。有一种方法 Attach 可以做到这一点。

xrm.Attach( pet );
pet["foodtype"] = "Seaweed";

xrm.UpdateObject( pet );
xrm.SaveChanges();
