            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.");

Answer 3

using System;
using System.IO;class Test 
{
    public static void Main() 
    {
        // Specify the directory you want to manipulate.
        string path = @"c:\MyDir";//换成时间        try 
        {
            // 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.");
        } 
        catch (Exception e) 
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        } 
        finally {}
    }
}

Answer 4

using System.IO;if(!Directory.Exists(System.DateTime.Now.ToString("yyyyMM"))
{
   Directory.CreateDirectory(System.DateTime.Now.ToString("yyyyMM"));
}

Answer 5

using System.IO;if(!Directory.Exists(System.DateTime.Now.ToString("yyyyMM"))
{
   Directory.CreateDirectory(System.DateTime.Now.ToString("yyyyMM"));
}还需要设置一下aspnet用户的目录操作权限

Answer 6

                ////创建当前日期的文件夹开始
                string dir = Server.MapPath("NewsFiles/" + DateTime.Now.ToString("yyyy-MM-dd"));  //用来生成文件夹
                if (!Directory.Exists(dir))
                {
                    Directory.CreateDirectory(dir);//判断是否这个年月日文件夹存在，不存在就创建
                }
在NewsFiles文件夹下面创建年月日的文件夹 
命名空间如下using System.IO;
using System.Text;

Answer 7

using System.IO; if(!Directory.Exists(System.DateTime.Now.ToString("yyyyMM"))

} 

Answer 8

            if (System.IO.Directory.Exists(DateTime.Now.ToString("yyyyMM"))
