Store your return value in a temporary variable like this:

public DataTable ReturnSomething()
{
    DataTable returnValue = null;

    try
    {
        //logic here
        returnValue = ds.Tables[0]; 
    }
    catch (Exception e)
    {
        ErrorString=e.Message;
    }

    return returnValue;
}
