亲爱的朋友们

我写了一个动态crm程序。在这里，我在服务上下文中获取产品，并希望更新产品。我编写代码以更新下面的条目。

Dear friends
I wrote a dynamics crm program. Here, I fetch products in the service context and want to update products. I write my code to update entry below.

XrmServiceContext svcContext;
...
// select one and update
var query = from c in svcContext.productSet
             where (c.ActivityId == id)
             select c;
foreach(Product c in query)
{
  c.LogicalName = "***"; // change logical name
  // change some fields
  svcContext.UpdateContact(c);
  svcContext.SaveChanges();
}

但从未更新过。请帮帮我。

But never been updated. Please help me.
