Entity Framework Extensions Ignore OnUpdate Expression
Description
The IgnoreOnUpdateExpression
allows you to ignore some columns when the BulkUpdate
method is executed.
The following example ignores the CreatedDate
property when bulk update operation is performed.
using (var context = new EntityContext()) { var customers = context.Customers.ToList(); customers.ForEach(x => { x.Name += "_Updated"; x.Description += "_Updated"; x.CreatedDate = DateTime.Now; x.ModifiedDate = DateTime.Now; x.IsActive = false; }); context.BulkUpdate(customers, options => { options.IgnoreOnUpdateExpression = customer => new { customer.CustomerID, customer.CreatedDate }; }); }
- It will update data in all the columns except for the
CreatedDate
column becauseCreatedDate
property is specified inIgnoreOnUpdateExpression
.
