asp.net(c#)如何创建以当前年月日为名称的文件夹?

[zhaoguo2007]

我想直接在虚拟空间的Products目录下动态生成文件夹,并以当前日期命名,请问该怎么做?

只有10分...不好意思了各位,帮帮忙~

Directory.CreateDirectory(path);

刚刚解决了创建...

if (System.IO.Directory.Exists(HttpContext.Current.Server.MapPath("Products/")+DateTime.Now.ToString("yyyyMMdd"))) //己经存在
{

}
else
{
System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("Products/")+DateTime.Now.ToString("yyyyMMdd"));
}

不知道删除要怎么做呢?

再请问下,我想用DropDownList控件的值的名称来创建文件夹有该怎么做?

我这样写:System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("Products/")+dll.SelectedItem.Value+"/"+DateTime.Now.ToString("yyyyMMdd"));

老是报错!
Compiler Error Message: CS0118: 'ASP.ChangeHtml_aspx.dll' denotes a 'field' where a 'class' was expected

DateTime t=System.DateTime.Now;
string dirName=HttpContext.Current.Server.MapPath("Products/")+t.ToString("yyyyMMddHHmmss")+dt.Millisecond.ToString();

try
{
if(System.IO.Directory.Exists(dirName)
{
throw new Exception("目录已存在");
return;
}
System.IO.Directory.CreateDirectory(dirName);
}
catch(Exception ee)
{
throw new Exception(ee.Message);
}

顶下~

[wolfs]

string UserDirectory = "TestFileId";//所要创建文件夹的名字，实际运用中可为用户注册ID
string UserPath = Server.MapPath("MT").ToString() + "\\" + UserDirectory + "\\" + "ProductsImages";

UserPath=Server.MapPath(UserPath);

if (!System.IO.Directory.Exists(UserPath)) //如果文件夹不存在则创建
{
Directory.CreateDirectory(UserPath);
}

直接在字符串中加上下拉框的值就o了吧

string UDirectory = "Products\\"+DropDownList.SelectedValue+"\\"+DateTime.Now.ToString("yyyyMMdd");

if (!System.IO.Directory.Exists(Server.MapPath(UDirectory)))
{
Directory.CreateDirectory(Server.MapPath(UDirectory));
}
