ADO.NET in a Nutshell

Name

OleDbException

Synopsis

This exception represents a data source error. For example, if you attempt to execute a SQL statement that is syntactically incorrect or open a connection to a database server that can’t be found, this exception is thrown. Every OleDbException contains at least one OleDbError object with data about the problem in the OleDbErrorCollection object. Errors that happen while disconnected from the data source (such as violating a System.Data.DataSet constraint or attempting to access a deleted row) result in a more specific exception from the System.Data namespace.

public sealed class OleDbException : System.Runtime.InteropServices.ExternalException {

// Public Instance Properties

   public override int ErrorCode{get; }             // overrides System.Runtime.InteropServices.ExternalException

   public OleDbErrorCollection Errors{get; } 

   public override string Message{get; }           // overrides Exception

   public override string Source{get; }             // overrides Exception

                  // Public Instance Methods

   public override void GetObjectData(System.Runtime.Serialization.SerializationInfo si,

        System.Runtime.Serialization.StreamingContext context);     // overrides Exception

}
