本文介绍了Groovy中遍历文件目录的方法，包括void eachDir(Closure closure)用于遍历子目录忽略普通文件，void eachDirMatch(Object nameFilter, Closure closure)用于按名称过滤子目录，以及eachDirRecurse(File self, Closure closure)用于递归遍历所有子孙目录。通过这些方法，可以方便地操作和管理文件系统中的目录结构。" 128362609,5679753,C#实现Word到RTF转换教程,"['C#开发', '编程语言', '文档转换', '游戏开发', '资源分享']

Common method：

1. void eachDir(Closure closure): Invokes the closure for each subdirectory in this directory, ignoring regular files.

class eachDirTest {
        public static void main(String[] args) {
            def count = 0
            def dir = new File("D:\\Project\\SoapUI\\Project-smoke-tests")

            dir.eachDir{directory->
                println directory
            }
        }  
}

2. void eachDirMatch(Object nameFilter, Closure closure): Invokes the closure for each subdirectory whose name (dir.name) matches the given nameFilter in the given directory - calling the DefaultGroovyMethods#isCase(java.lang.Object, method to determine if a match occurs.

class eachDirTest {
    public static void main(String[] args) {
        def count = 0
        def dir = new File("D:\\Project\\SoapUI\\Project-smoke-tests")

        dir.eachDirMatch(~/^Sanity.*/){d ->
            println d
        }
    } 
}

Output:
D:\Project\SoapUI\Project-smoke-tests\SanityTestSuite1
D:\Project\SoapUI\Project-smoke-tests\SanityTestSuite2
D:\Project\SoapUI\Project-smoke-tests\SanityTestSuite3
D:\Project\SoapUI\Project-smoke-tests\SanityTestSuite4
D:\Project\SoapUI\Project-smoke-tests\SanityTestSuite5
……..

3. eachDirRecurse(File self, Closure closure) : Invokes the closure for each descendant directory of this directory.

class eachDirTest {
        public static void main(String[] args) {
            def count = 0
            def dir = new File("D:\\Project\\SoapUI\\Project-smoke-tests")

            dir.eachDirRecurse{directory->
                println directory
            }
        }  
}
