Remarks

This class is created whenever the .NET Compact Framework Data Provider for SQL Server Compact 3.5 SP1 encounters an error generated from within the SQL Server Compact 3.5 SP1 Engine. (Other errors are thrown as standard common language runtime exceptions.) SqlCeException always contains at least one instance of SqlCeError.

Example

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

Dim conn As New SqlCeConnection("Data Source=nonExistingSource.sdf;")

Try
    conn.Open()
Catch e As SqlCeException
    ' Use SqlCeException properties if you need specific
    ' application logic depending on the error condition
    '
    If 25046 = e.NativeError Then 'SSCE_M_FILENOTFOUND
        ' Error specific logic goes here...
        '
    End If

    MessageBox.Show(e.Message)
End Try

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);
}
