SqlCeException Class

This class is created whenever the .NET Compact Framework Data Provider for SQL Server Compact encounters an error generated from within the SQL Server Compact Engine. (Other errors are thrown as standard common language runtime exceptions.) SqlCeException always contains at least one instance of SqlCeError.

The following example generates a SqlCeException due to a missing data source, and then displays the exception.

SqlCeConnection conn = new SqlCeConnection("Data Source=nonExistingSource.sdf;");

try
{
    conn.Open();
}
catch (SqlCeException e)
{
    // Use SqlCeException properties if you need specific
    // application logic depending on the error condition
    //
    if (25046 == e.NativeError /*SSCE_M_FILENOTFOUND*/)
    {
        // Error specific logic goes here...
        //
    }

    MessageBox.Show(e.Message);
}
