c#递归遍历文件夹示例

前端技术 2023/09/10 C#

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);
}
}
}
}
