本文介绍了一个使用C#编写的递归函数，该函数能够遍历指定路径下的所有子目录及文件，并打印出它们的完整路径。此方法适用于需要处理文件系统层级结构的应用场景。
public static void fun(string path)
{
path += "\\";
if (Directory.GetDirectories(path).Length == 0)
{
Console.WriteLine(path);
foreach (string name in Directory.GetFiles(path))
Console.WriteLine(name);
return;
}
else
{
Console.WriteLine(path);
foreach (string name in Directory.GetDirectories(path))
fun(name);
foreach (string name in Directory.GetFiles(path))
Console.WriteLine(name);
}
}
{
path += "\\";
if (Directory.GetDirectories(path).Length == 0)
{
Console.WriteLine(path);
foreach (string name in Directory.GetFiles(path))
Console.WriteLine(name);
return;
}
else
{
Console.WriteLine(path);
foreach (string name in Directory.GetDirectories(path))
fun(name);
foreach (string name in Directory.GetFiles(path))
Console.WriteLine(name);
}
}
