The OleDbException type exposes the following members.

  Name Description
Public property Data Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
Public property ErrorCode Gets the HRESULT of the error. (Overrides ExternalException.ErrorCode.)
Public property Errors Gets a collection of one or more OleDbError objects that give detailed information about exceptions generated by the .NET Framework Data Provider for OLE DB.
Public property HelpLink Gets or sets a link to the help file associated with this exception. (Inherited from Exception.)
Protected property HResult Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
Public property InnerException Gets the Exception instance that caused the current exception. (Inherited from Exception.)
Public property Message Gets a message that describes the current exception. (Inherited from Exception.)
Public property Source Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
Public property StackTrace Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.)

This class is created whenever the .NET Framework Data Provider for OLE DB encounters an error generated from the server. (Client side errors are thrown as standard common language runtime exceptions.) OleDbException always contains at least one instance of OleDbError.

If the severity of the error is too great, the server may close the OleDbConnection. However, the user can reopen the connection and continue.

For general information about handling exceptions for a .NET Framework data provider, see SqlException.

The following example generates an OleDbException because of a missing data source, and then displays the exception.


public void ShowOleDbException() 
{
   string mySelectQuery = "SELECT column1 FROM table1";
   OleDbConnection myConnection =
      new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;DataSource=");
   OleDbCommand myCommand = new OleDbCommand(mySelectQuery,myConnection);

   try 
   {
      myCommand.Connection.Open();
   }
   catch (OleDbException e) 
   {
     string errorMessages = "";

     for (int i=0; i < e.Errors.Count; i++)
     {
         errorMessages += "Index #" + i + "\n" +
                          "Message: " + e.Errors[i].Message + "\n" +
                          "NativeError: " + e.Errors[i].NativeError + "\n" +
                          "Source: " + e.Errors[i].Source + "\n" +
                          "SQLState: " + e.Errors[i].SQLState + "\n";
     }

     System.Diagnostics.EventLog log = new System.Diagnostics.EventLog();
     log.Source = "My Application";
     log.WriteEntry(errorMessages);
     Console.WriteLine("An exception occurred. Please contact your system administrator.");
   }
}
