DBConcurrencyException serializable

DBConcurrencyException serializable

System.Data (system.data.dll) sealed class

The exception is thrown by a DataAdapter if an attempt to update, delete, or insert a row results in zero affected rows. For example, if a data adapter attempts to execute a SQL DELETE statement to remove the record corresponding to a deleted DataRow from the data source, and no rows are deleted, this exception will be thrown. This exception usually indicates that another user has already modified the row you are attempting to update and a matching row can't be found. You can suppress the DBConcurrencyException by setting the System.Data.Common.DataAdapter.ContinueUpdateOnError property to true , in which case invalid rows are skipped , and the error information is placed in the DataRow.RowError property of rows having errors. Alternatively, you can respond to concurrency errors during the update (and suppress them if needed) by handling the data adapter's RowUpdating event.

 public sealed class  DBConcurrencyException  : SystemException {  // Public Constructors  public  DBConcurrencyException  (  );      public  DBConcurrencyException  ( string   message   );      public  DBConcurrencyException  (string   message   , Exception   inner   );  // Public Instance Properties  public DataRow  Row  {set; get; }  // Public Instance Methods  public override void  GetObjectData  (System.Runtime.Serialization.SerializationInfo   si   ,          System.Runtime.Serialization.StreamingContext   context   );  // overrides Exception  }
