正则表达式检查“+="方法内部 [英] Regex to check for "+=" inside of a method

问题描述

通过我们的代码库，我们的许多自定义控件都有一个 DetachEvents 方法，该方法在控件被释放时被调用.很多时候，其他开发人员错误地是事件处理程序

Going through our codebase, many of our custom controls have a DetachEvents method that gets called with the control is being disposed. Quite frequently, other developers incorrectly are the event handler

private void DetachEvents()
{
    myControl.Click += new EventHandler(myControl_Click);
}

当然，什么时候应该是 -= 而不是 +=.

When it should, of course, be -= instead of +=.

我正在尝试为 Find & 想出一个正则表达式.替换 Visual Studios 中的工具，只找到包含 += 的 DetachEvent 方法，但我不知道如何做.如果我继续查找 DetachEvents()

I'm trying to come up with a regex for the Find & Replace tool in Visual Studios to only find me DetachEvent methods that contain the += but I cannot figure out how to. I'll be here all day if I just keep Finding every occurance of DetachEvents()

我试过:DetachEvents()[.]+=[.] 认为该句点会在 += 之前和之后找到任何东西，但它没有找到任何东西.

I tried: DetachEvents()[.]+=[.] thinking the period would find anything before and after the += but it doesn't find anything.

推荐答案

尝试转义 +:

DetachEvents().*\+=

但这将匹配 DetatchEvents() 之后的任何 += 实例.您可能想要使用 [^}] 而不是 .，假设您在 DetachEvents 方法中没有任何其他代码块:

But this will match any instance of += which follows DetatchEvents(). You might want to use [^}] instead of ., assuming you don't have any other code blocks inside the DetachEvents method:

DetachEvents()[^}]*\+=
