C#如何遍历某目录的所有文件？

[不懂必须要问]

这个目录下有很多子目录和文件的。

[mywisest]

DirectoryInfo
GetDirectories
GetFiles
递归即可。

递归 调用自身函数

[无聊的一个人啊]

/// <summary>
/// 复制目录A到B
/// </summary>
/// <param name="OldDirectory">原目录</param>
/// <param name="NewDirectory">新目录</param>
public static void CopyDirectory(DirectoryInfo OldDirectory, DirectoryInfo NewDirectory)
{
string NewDirectoryFullName = NewDirectory.FullName + @"\" + OldDirectory.Name;
if (!Directory.Exists(NewDirectoryFullName))
Directory.CreateDirectory(NewDirectoryFullName);

FileInfo[] OldFileAry = OldDirectory.GetFiles();
foreach (FileInfo aFile in OldFileAry)
File.Copy(aFile.FullName, NewDirectoryFullName + @"\" + aFile.Name, true);

DirectoryInfo[] OldDirectoryAry = OldDirectory.GetDirectories();
foreach (DirectoryInfo aOldDirectory in OldDirectoryAry)
{
DirectoryInfo aNewDirectory = new DirectoryInfo(NewDirectoryFullName);
CopyDirectory(aOldDirectory, aNewDirectory);//递归调用
}
}

//这是一个用遍历复制文件夹的一个函数,楼主可以参考一下

新学，不太会用，得一个就懂……


麻烦朋友帮帮忙。

DirectoryInfo dir = new DirectoryInfo(AppPath + "Temp");
FileInfo[] fileInfo = dir.GetFiles();

这就是取AppPath + "Temp"该路劲下所有的文件，照葫芦把所有的弄出来就是了

System.IO.Directory.DirectoryInfo
System.IO.Directory.GetDirectories
System.IO.Directory.GetFiles

GetDirectories
GetFiles
递归即可。

            string[] filename = System.IO.Directory.GetFiles("C:\abc", "*.*", SearchOption.AllDirectories);
