您可以传递Action给您的方法.

ResponseStatus GetPotatoList(Action action1, Action action2, GetPotatosRequest requestParam, out GetPotatosResponse response, out ResponseErrorType errorType)
{
    ResponseStatus status = ResponseStatus.Fail;
    response = new GetPotatosResponse();

    action1();

    try
    {
        action2();
        status = ResponseStatus.Success;
    }
    catch(CustomException ex)
    {
        errorType = ResponseErrorType.CustomError;
    }
    catch(TimeoutException ex)
    {
        errorType = ResponseErrorType.Timeout;
    }
    catch(Exception ex)
    {
        errorType = ResponseErrorType.GeneralFailure;
    }

    return status;
}

然后使用它:

var response = GetPotatoList(
    () => doSomething(),
    () => doSomethingElse(),
    requestParam,
    out response,
    out errorType);
