怎样通过网页来新建文件夹

Question

调用.NET的文件操作类库应该能成吧！我在Winform中用过，不过再Webform中没用过

Answer 1

使用的directory类:
创建目录:Directory.CreateDirectory("yourpath")
使用File类复制文件:
复制文件:file.copy("源URL","目的url",true) 'true表示存在时是否覆盖

Answer 2

新建一个文件夹using System;
using System.IO;class Test 
{
    public static void Main() 
    {
        // Specify the directory you want to manipulate.

        {
            // Determine whether the directory exists.
            if (Directory.Exists(path)) 
            {
                Console.WriteLine("That path exists already.");
                return;
            }            // Try to create the directory.
            DirectoryInfo di = Directory.CreateDirectory(path);
            Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));            // Delete the directory.
            di.Delete();
            Console.WriteLine("The directory was deleted successfully.");
        }
