This class represents one or more data source errors, but it isn't an exception. Instead, the data source may report multiple errors, and multiple OleDbError instances may be added to a single OleDbErrorCollection , which are then accessed using the OleDbException.Errors property of the exception that is raised.

OLE DB errors contain information including a database-specific error code (NativeError ), a five-character code following the ANSI SQL standard (SQLState ), and a descriptive text message (Message ).

public sealed class OleDbError {
// Public Instance Properties
   public string Message{get; } 
   public int NativeError{get; } 
   public string Source{get; } 
   public string SQLState{get; } 
// Public Instance Methods
   public override string ToString(  );          // overrides object
}
