asp.2.0关于FileUpload控件

在asp.2.0中，FileUpload控件选择上传路径时，关于（string ipath = Server.MapPath("image") + "\\" + name;）中，在上传图片时，参数“image”必须和要上传的图片所在的文件夹名称相同，否则就不行！
请问：我们在做网页时，要对方随便在哪里都可以上传，参数应该怎样设置？？？或者是用其他的方法？？
string name = fupFhoto.FileName;
string size = fupFhoto.PostedFile.ContentLength.ToString();
string type = fupFhoto.PostedFile.ContentType;
string type2=name.Substring(name.LastIndexOf(".")+1);
string ipath = Server.MapPath("image") + "\\" + name;
string fpath = Server.MapPath() + "\\" + name;
string wpath = "image\\" + name;

if (type2 == "jpg" || type2 == "gif")
{
fupFhoto.SaveAs(ipath);
Image1.ImageUrl = wpath;
Label1.Text = "你传的文件是：" + name + "<br>大小是" + size + "<br>类型是" + type;
}
else
{
Image1.Visible = false;
fupFhoto.SaveAs(fpath);
Label1.Text = "你传的是什么啊？";
}
}
}
-------------------------
能不能给段代码，举个例子！！
再三感谢！！！

Answer 1

public static string FileUpAndReturnGetNewFileNameRAR(Page p, FileUpload fileUpload, string ver)
{//根据上传页面,上传控件,语言,返回上传后新文件的名称
string newfilename = "";

if (fileUpload.HasFile)
{
string fileExt =
System.IO.Path.GetExtension(fileUpload.FileName);

try
{
newfilename = ver + "_" + GetNewFileName(fileUpload.FileName.ToString()).ToLower();
if (File.Exists(p.Server.MapPath("~/Uploads/" + newfilename)) == false)
{

fileUpload.SaveAs(p.Server.MapPath("~/Uploads/" + newfilename));
}
else
{
//newfilename = ver + "_" + GetNewFileName(fileUpload.FileName.ToString()).ToLower();
//fileUpload.SaveAs(p.Server.MapPath("~/Uploads/" + newfilename));
FunctionClass.ErrorMsg(p, "该文件已经存在!");
}
}
catch (Exception ex)
{
FunctionClass.ErrorMsg(p.Page, "错误:: " + ex.Message.ToString());
}
}

return newfilename;
}
public static string GetNewFileName(string FileName)
{//跟据文伯名产生一个由时间+随机数组成的一个新的文件名

string newfilename = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString()
+ DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString()
+ DateTime.Now.Second.ToString() + DateTime.Now.Minute.ToString()
+ DateTime.Now.Millisecond.ToString()
//+ rand.Next(1000).ToString()
+ FileName.Substring(FileName.LastIndexOf("."), FileName.Length - FileName.LastIndexOf("."));
return newfilename;
}

保存文件时把文件名改成年日期时间这样就不会重名传一起也没问题了
