ADO.NET in a Nutshell

This is the base class for all exceptions in this namespace. Provider-specific exception classes (such as System.Data.SqlClient.SqlException ), which represent errors that are raised when executing a command or accessing a connection, don't derive from this class.

public class DataException : SystemException { // Public Constructors public DataException ( ); public DataException (string s ); public DataException (string s , Exception innerException ); // Protected Constructors protected DataException (System.Runtime.Serialization.SerializationInfo info , System.Runtime.Serialization.StreamingContext context ); }
