一个递归函数：

#region 树控件,遍历文件夹

public void GetSpecFF(string Folder,TreeNodeCollection who)
{
string[]dires=Directory.GetDirectories(Folder);
foreach(string dire in dires)
{
string[]filepart=dire.Split('\\');
string filename=filepart[filepart.Length-1].ToString();//析取文件名
TreeNode newNode = new TreeNode();
newNode.Text=filename;
newNode.ID=dire;
newNode.ImageUrl=@"/GreatOA/Images/Icon/005.gif";
who.Add(newNode);
GetSpecFF(dire,newNode.Nodes);
}
string[]files=Directory.GetFiles(Folder);
foreach(string file in files)
{
string[]filepart=file.Split('\\');
string filename=filepart[filepart.Length-1].ToString();
TreeNode newNode = new TreeNode();
newNode.Text=filename;
newNode.ID=file;//保存全路径
newNode.ImageUrl=@"/GreatOA/Images/Icon/046.gif";
who.Add(newNode);
}
}
#endregion

//获取文件名，没有子目录
using System;
using System.IO;

class Test
{
public static void Main()
{
try
{
// Only get files that begin with the letter "c."
string[] dirs = Directory.GetFiles(@"c:\", "c*");
Console.WriteLine("The number of files starting with c is {0}.", dirs.Length);
foreach (string dir in dirs)
{
Console.WriteLine(dir);
}
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}

如果要获取子目录，就用
using System;
using System.IO;

class Test
{
public static void Main()
{
try
{
// Only get subdirectories that begin with the letter "p."
string[] dirs = Directory.GetDirectories(@"c:\", "p*");
Console.WriteLine("The number of directories starting with p is {0}.", dirs.Length);
foreach (string dir in dirs)
{
Console.WriteLine(dir);//这里递归
}
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
}

原理：http://www.microsoft.com/china/technet/community/scriptcenter/resources/hey1020.mspx

不取得子目录的话用这个：
using System.IO;
string[] dirs = Directory.GetDirectories(@"c:\");//路径
foreach (string dir in dirs)
{
Console.WriteLine(dir);
}
文件的话把GetDirectories改成GetFiles

如果要递归的话，就是想取得此目录下所有子目录和文件的办法用这个：
public void FindFile(string dir) //参数为指定的目录
{
//在指定目录及子目录下查找文件,在listBox1中列出子目录及文件
DirectoryInfo Dir=new DirectoryInfo(dir);
try
{
foreach(DirectoryInfo d in Dir.GetDirectories()) //查找子目录
{
FindFile(Dir+d.ToString()+"\\");
listBox1.Items.Add(Dir+d.ToString()+"\\"); //listBox1中填加目录名
}
foreach(FileInfo f in Dir.GetFiles("*.*")) //查找文件
{
listBox1.Items.Add(Dir+f.ToString()); //listBox1中填加文件名
}
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}

}

调用
private void button1_Click(object sender, System.EventArgs e)
{
string currentdir="F:\\myprogram\\C#\\FileSearch"; //搜索的目录
if(currentdir[currentdir.Length-1]!='\\') //非根目录
currentdir+="\\";
FindFile(currentdir); //调用查找文件函数
}

注意 using System.IO;
