Thrown when an update fails because database values have been updated since the client last read them.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
The following example shows how this exception might be used for returning information about a concurrency conflict.
Northwnd db = new Northwnd("..."); try { db.SubmitChanges(ConflictMode.ContinueOnConflict); } catch (ChangeConflictException e) { Console.WriteLine("Optimistic concurrency error."); Console.WriteLine(e.Message); foreach (ObjectChangeConflict occ in db.ChangeConflicts) { MetaTable metatable = db.Mapping.GetTable(occ.Object.GetType()); Customer entityInConflict = (Customer)occ.Object; Console.WriteLine("Table name: {0}", metatable.TableName); Console.Write("Customer ID: "); Console.WriteLine(entityInConflict.CustomerID); Console.ReadLine(); } }
