Source: Internet

During self-development, we found that there was a conflict when using mvc to update data. Let's take a look at the solution below for reference.

The Code is as follows: Copy code

 

Public abstract class dbBase
{

Public virtual void SubmitChanges ()
{
ChangeSet cSet = db. GetChangeSet ();
If (cSet. Inserts. Count> 0
| CSet. Updates. Count> 0
| CSet. Deletes. Count> 0)
{
Try
{
Db. SubmitChanges (System. Data. Linq. ConflictMode. ContinueOnConflict );
// Db. SubmitChanges ();
}
Catch (System. Data. Linq. ChangeConflictException ex)
{
Foreach (System. Data. Linq. ObjectChangeConflict occ in db. ChangeConflicts)
{

// Use the value in the current database to overwrite the value of the entity object in the Linq Cache
Occ. Resolve (System. Data. Linq. RefreshMode. OverwriteCurrentValues );

// Use the value of the entity object in the cache of Linq to overwrite the value in the current database.
Occ. Resolve (System. Data. Linq. RefreshMode. KeepCurrentValues );

// Only update the value of the changed field in the object. Other values remain unchanged.
Occ. Resolve (System. Data. Linq. RefreshMode. KeepChanges );
}
Db. SubmitChanges ();
}
}
}

}

All data operation objects inherit from it and use its SubmitChanges method.
