通用函数包装器 [英] Generic Function wrapper

问题描述

我有很多功能不同的内容，但是参数和try catch内部几乎相似.无论如何，有没有要包装的功能，以减少多余的代码.

I have many functions with different content but the parameters and try catch inside is almost similar. Is there anyway to wrap the function up so that can reduce redundant codes.

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

    //To Do

    try
    {

        //To Do

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

    return status;
}

推荐答案

您可以将Action传递给您的方法.

You can pass an Action to your method.

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);
