如何使用对象上下文在实体框架中使用批量插入？

Question

I would like to use Object Context instead of DbContext to call Bulk Insert in Entity Framework 6. How can I do that?

I would like to do something like

readonly ObjectContext obContext :

public void BulkInsert<T>(IEnumerable<T> items) where T : class, new()
{
    obContext.BulkInsert(items);
}

But I am not able to do this.

Answer 1

With entity framework 6, you can use this nice nuget package to bulk insert, and you can use it with the DbContext object.

so something like this:

using (var db = new YourDbContext())
{
   EFBatchOperation.For(db, db.BlogPosts).InsertAll(list);
}

Hope this helps.

Answer 2

With EntityFrame 6 you do insert a range of elements.

For example, i add a model Customer

public class Customer
{
  public int Id {get; set;}
  public string CustomerName {get;set;}
  public string City {get;set;}
}

If I send List of customer from view like List of models (List), I can save range of data like:

public ActionResult AddCustomerData(List<Customer> cust)
{
  try
  {
    using(var db = new DBContext)
    {
      db.customer.AddRange(cust);
      db.SaveChanges();
    }
  }
  catch(exception ex)
  {
  }
}

Like this you can add bulk/range of data to tha database and before adding you can modify data if you want also. Thank you.
