Answer 2

string[] dirs = Directory.GetDirectories(@"c:\");
string[] files = Directory.GetFiles(@"c:\");

Answer 3

ArrayList a = new ArrayList();
DirectoryInfo d = new DirectoryInfo("c:\\");FileInfo[] fis = d.GetFiles();
foreach (FileInfo fi in fis) 
        {      
              a.Add(fi.Name);
        }
       
DirectoryInfo[] dis = d.GetDirectories();
foreach (DirectoryInfo di in dis) 
        {
             a.Add(di.Name);              
        }

Answer 4

private void Form1_Load(object sender, System.EventArgs e)
{
this.getTreenode("你的目录",treeView1.Nodes );
}private void getTreenode(string path,System.Windows.Forms.TreeNodeCollection nodes)
{
string [] folders=System.IO.Directory.GetDirectories(path);
string [] files=System.IO.Directory.GetFiles(path);
foreach(string folder in folders)
{
              nodes.Add(node(folder));
}
foreach(string file in files)
{
  nodes.Add(node(file));
}
for(int i=0;i<folders.Length ;i++)
{
this.getTreenode(folders[i],nodes[i].Nodes );
}
} public  System.Windows.Forms.TreeNode node( string text)
{
System.Windows.Forms.TreeNode n = new  System.Windows.Forms.TreeNode();
//节点值
n.Text=text;

return n;
}

Answer 5

如果你只想得到文件名称 如a.txt得到a
string Extension = fiTemp.Extension;
string fileName = fiTemp.Name.Remove(fiTemp.Name.Length-Extension.Length,Extension.Length);请问怎么把他们打印到控制台？ArrayList a = new ArrayList();
DirectoryInfo d = new DirectoryInfo("c:\\");FileInfo[] fis = d.GetFiles();
foreach (FileInfo fi in fis) 
        {      
              a.Add(fi.Name);
              Console.WriteLine(fi.Name);
        }
       
DirectoryInfo[] dis = d.GetDirectories();
foreach (DirectoryInfo di in dis) 
        {
             a.Add(di.Name);
Console.WriteLine(di.Name);              
        }
