有多少参数在C＃中的方法是可以接受的？ [英] How many parameters in C# method are acceptable?

问题描述

我是新的C＃和必须保持一个C＃应用程序。
现在我发现，有32个参数（不自动生成的代码）的方法。

I am new to C# and have to maintain a C# Application. Now I've found a method that has 32 Parameters (not auto-generated code).

从C / C ++我记得拇指法则4参数。这可能是一个老式的规则生根回到老0x86可以编译器，其中4参数可在寄存器（快速）被安置或以其他方式堆栈。

From C/C++ I remember the rule of thumb "4 Parameters". It may be an old-fashioned rule rooting back to old 0x86 compilers, where 4 Parameters could be accommodated in registers (fast) or on stack otherwise.

我不关注关于性能，但我有一种感觉，每个功能的32个参数是不易保持，甚至在C＃。

I am not concerned about performance, but I do have a feeling that 32 parameters per functions are not easy to maintain even in C#.

还是我完全不是最新的？

Or am I completely not up to date?

什么是经验的C＃的规则？

What is the rule of thumb for C#?

感谢您的任何暗示！

推荐答案

有没有普遍的共识，这取决于谁你问

There is no general consensus and it depends on who you ask.

在一般 - 瞬间可读性受到影响，有太多的...

In general - the moment readability suffers, there are too many...

鲍勃·马丁说的参数理想的数字是0和3拉伸。

Bob Martin says the ideal number of parameters is 0 and that 3 is stretching it.

32个参数是一个庞大的代码味道。这意味着该类有太多的责任，需要进行重构。即使应用参数对象重构听起来好像它会躲在一个不好的设计，而不是解决问​​题。

32 parameters is a massive code smell. It means the class has way too many responsibilities and needs to be refactored. Even applying a parameter object refactoring sounds to me like it would hide a bad design rather than solve the issue.

＃周10 <清洁代码提示/一>：

From Clean Code Tip of the Week #10:

函数应该有一个小数目的参数。没有参数​​是最好的，其次是一，二，三。三多是非常可疑的，应偏见是可以避免的。

Functions should have a small number of arguments. No argument is best, followed by one, two, and three. More than three is very questionable and should be avoided with prejudice.
