请对这块熟悉的朋友介绍下，谢谢

Answer 1

            DirectoryInfo dirinfo = new DirectoryInfo("路径");
            if (!dirinfo.Exists)
                return;            foreach (FileInfo f in dirinfo.GetFiles("*.*"))
            {
                  f.Name ; //楼主自己发挥了
            }

Answer 2

//将内容写入到"c:\\a.txt"文件中
FileStream fs = new FileStream("c:\\a.txt", FileMode.Create, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);DirectoryInfo dirinfo = new DirectoryInfo("路径"); 
if (!dirinfo.Exists) 
     return; foreach(DirectoryInfo di in dirinfo.GetDirectories())
{
     sw.WriteLine("文件夹:" + di.FullName + "\n");
     sw.Flush();
}foreach (FileInfo f in dirinfo.GetFiles("*.*")) 
{ 
     sw.WriteLine("文件:" + f.FullName + "\n");
     sw.Flush(); 
}sw.Close();
fs.Close();

Answer 3

感觉不能写"非文件夹"的文件名称。
文件夹的子文件夹也没找出来using System.IO;  //文件输入输出        private void button3_Click(object sender, EventArgs e)
        {
            string DirPath = "";
            DirPath = this.txt_DirPath.Text.Trim().ToString();            //将内容写入到"d:\\a.txt"文件中
            FileStream fs = new FileStream("d:\\a.txt", FileMode.Create, FileAccess.Write);
            StreamWriter sw = new StreamWriter(fs);            DirectoryInfo dirinfo = new DirectoryInfo(DirPath);
            if (!dirinfo.Exists)
                return;            //写文件夹名称
            foreach (DirectoryInfo di in dirinfo.GetDirectories())
            {
                sw.WriteLine("文件夹:" + di.FullName + "\n");
                sw.Flush();
            }            //写非文件夹名称(该循环语句不执行)
            foreach (FileInfo f in dirinfo.GetFiles("*.*"))
            {
                sw.WriteLine("文件:" + f.FullName + "\n");
                sw.Flush();
            }            sw.Close();
            fs.Close();
        }

private  string forFileLength(DirectoryInfo   directory)   
{   
     StringBuilder sb=new StringBuilder ();
    DirectoryInfo[]   directorys   =   directory.GetDirectories();   
    FileInfo[]   files;   
    foreach   (DirectoryInfo   di   in   directorys)   
    {   
         sb.Append(forFileLength(di));   
    }   
    files   =   directory.GetFiles(); 
    foreach(FileInfo   file   in   files)   
    {   
        string temp = file.DirectoryName.ToString();       
        string name = file.Name;    
       sb.Append(temp +name);
    }  
return sb.ToString(); 
}
