C#Regex以匹配目录模式

我想在Directory.GetAllDirectories（）上运行正则表达式 e、 g

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

目录遵循如下模式：

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

[Variable number of Directory]\$PROJECT$\$TYPE$\$BRANCH$\[Variable 目录数目]

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

我想忽略第一组[Variable number of Directory]，后面正好是3个目录。我不想包括在$BRANCH$目录之后有任何内容的目录。$TYPE$目录必须是“Ft”或“Dev”

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

我有下面的模式，几乎可以工作

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

string pattern = @"\w+\\(Ft|Dev)\\";

不幸的是，这种模式也会抓取$BRANCH$文件夹之后的所有文件夹

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

具体来说，文件夹列表如下所示：

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

• C:\Users\Me\Desktop\Project\Dev\Branch\
• C:\Users\Me\Desktop\Project\Dev\Branch\sub\sub
• C:\Users\Me\Desktop\Project\Ft\Branch\sub\sub
• C:\Users\Me\Desktop\Project\Ft\Branch\
• C:\Users\Me\Desktop\Project\Qa\Branch\
• C:\Users\Me\Desktop\Project\Qa\Branch\sub\sub

应在正则表达式之后过滤到以下内容：

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

• C:\Users\Me\Desktop\Project\Dev\Branch
• C:\Users\Me\Desktop\Project\Ft\Branch

---

编辑：清除目录模式上的格式设置

您可以使用此模式执行此操作：

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();

@"\w\\(?:Ft|Dev)\\Branch\\?$"

---

其中，

$

是字符串结尾的锚点。

在正则表达式末尾添加“^”：@“\w+\（Ft|Dev）\\Branch\\\^”0匹配，当我这样做时。$'抱歉。。。我把“$”和“^”混在一起了。一个表示开始，另一个表示结束。这是有效的：模式=@“\w\\（Ft|Dev）\\\w+\\？$”；谢谢

 Directory.GetDirectories(pathToMonitor, "*.*", SearchOption.AllDirectories)
.Where(path => new Regex(pattern, RegexOptions.IgnoreCase).IsMatch(path))
.ToList();
