理论上的最佳值为：
虽然可以做出一些一般性的陈述，但没有硬性规定的“好”范围。
一个项目只能通过本质上不做任何事情并且毫无用处才能同时达到所有四个价值：不做任何事情并且不依赖任何东西的软件当然是可维护的，但不能很好地利用客户的资金。
因此，所有的复杂性都是一种权衡：额外的所谓的固有复杂性将更多的复杂性编码到程序中，从而允许它扩展功能集。您希望避免的是由于实施不当或有缺陷而导致的意外复杂性。
The theoretically optimal values are:
There are no hard and fast "good" ranges, though it's possible to make some general statements.
A project could only reach all four values simultaneously by essentially doing nothing and being useless: software that does nothing and depends on nothing is certainly maintainable, but not a very good use of client dollars.
Therefore, all complexity is a tradeoff: additional so-called inherent complexity encodes more sophistication into the program, allowing it to expand the feature set. What you would like to avoid is accidental complexity introduced by a poor or deficient implementation.
在过度依赖它（或完全依赖它）之前，请检查以下页面，其中提供了有关如何计算指标的更多详细信息：
https://avandeursen.com/2014/08/29/think-twice-before-using-the-maintainability-index/ VS 的可维护性指数是一个未经充分验证的指标组合
，它本身依赖于一个指标（圈复杂度），该指标已被证明与代码可理解性不相关（因此与可维护性不相关）。请参阅 Scalabrino 等人的“自动评估代码可理解性：我们还有多远？”。
和 https://shape-of-code.com/?s=cyclomatic+complexity
此外，该指标中使用的常量和函数选择尚未在 C# 或 VB 代码上进行校准，这进一步使其毫无用处。
（这通过指出甚至不应该问原始问题来解决原始问题。）
Before relying too heavily on it (or relying on it at all), check the following page, which gives more detail on how the metric is computed:
https://avandeursen.com/2014/08/29/think-twice-before-using-the-maintainability-index/
VS' Maintainability Index is a poorly-validated combination of metrics, which itself relies a metric (cyclomatic complexity) that has been shown to not correlate with code understandability (which would therefore not correlate with maintainability). See "Automatically Assessing Code Understandability: How Far Are We?", by Scalabrino et al.
and https://shape-of-code.com/?s=cyclomatic+complexity
Furthermore, the constants and function choices used in this metric have not been calibrated on C# or VB code, which further makes it useless.
(This addresses the original question by pointing out that the original question should not even be asked.)
