Entity Framework Extensions PreBulkSynchronize
Description
The PreBulkSynchronize
event is raised as soon as the BulkSynchronize
method is called and no configuration or anything else is done before. It allows you to set some global configuration for BulkSynchronize
.
Example
The following example sets the CreatedDate
for new customers and ModifiedDate
property for existing customers.
EntityFrameworkManager.PreBulkSynchronize = (ctx, obj) => { if (obj is IEnumerable<Customer>) { foreach (var customer in (IEnumerable<Customer>)obj) { if (customer.CustomerID == 0) { customer.CreatedDate = DateTime.Now; } else { customer.ModifiedDate = DateTime.Now; } } } };
Try it in EF Core | Try it in EF6
In the PreBulkSynchronize
event, the CreatedDate
for new customers and ModifiedDate
property for existing customers is set to DateTime.Now
before the data is synchronized to the database.
