代码很简单，指定需要递归遍历的文件夹和遍历规则就要可以运行了

复制代码 代码如下:

/// <summary>

/// 递归获取文件夹目录下文件

/// </summary>

/// <param name="pathName">需要递归遍历的文件夹</param>

/// <param name="fileRule">遍历规则『委托』</param>

public static void LoopFolder(string pathName, Action<FileInfo> fileRule)

{

if (string.IsNullOrEmpty(pathName))

throw new ArgumentNullException(pathName);

Queue<string> _pathQueue = new Queue<string>();

_pathQueue.Enqueue(pathName);

while (_pathQueue.Count > 0)

{

string _path = _pathQueue.Dequeue();

DirectorySecurity _pathSecurity = new DirectorySecurity(_path, AccessControlSections.Access);

if (!_pathSecurity.AreAccessRulesProtected)//文件夹权限是否可访问

{

DirectoryInfo _directoryInfo = new DirectoryInfo(_path);

foreach (DirectoryInfo diChild in _directoryInfo.GetDirectories())

{

_pathQueue.Enqueue(diChild.FullName);

}

foreach (FileInfo file in _directoryInfo.GetFiles())

{

fileRule(file);

}

}

}

}

举例使用

复制代码 代码如下:

CSharpToolV2.LoopFolder(@"C:UsersAdministratorDownloads", (FileInfo file) =>

{

if (file.Extension.Equals(".xls"))//获取excel类型文件

{

Console.WriteLine(string.Format("============{0}==============", file.FullName));

}
