creating a directory during runtime

[Newbie]

hi!

i am able to upload files successfully. but i have one minor problem. files
are uploaded correctly if the directory exists, it is throwing an exception
if the directory doesnt exist. but the directory name is created during
runtime. is there a way to create a directory during runtime?

exception:
Error saving file C:\temp\188\
System.IO.Direc toryNotFoundExc eption: Could not find a part of the path
"C:\temp\188\_d s27.tmp". at System.IO.__Err or.WinIOError(I nt32 errorCode,
String str) at System.IO.FileS tream..ctor(Str ing path, FileMode mode,
FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync,
String msgPath, Boolean bFromProxy) at System.IO.FileS tream..ctor(Str ing

mole.proposals. dltaskorders.ad dTaskOrder.btnU pload_Click(Obj ect sender,
EventArgs e) in c:\inetpub\wwwr oot\dltaskorder s\addtaskorder. aspx.cs:line 286

code:
private void btnUpload_Click (object sender, System.EventArg s e)
{
string baseLocation = "C:\\temp\\ " + Session["sReference "].ToString()
+ "\\";
string status = "";
if((lstAttachme nts.Items.Count == 0) && (filesUploaded == 0))
{
lblError.Text = "Error - a file name must be specified.";
return;

}
else
{
foreach(System. Web.UI.HtmlCont rols.HtmlInputF ile HIF in hif)
{
try
{
string fn =
System.IO.Path. GetFileName(HIF .PostedFile.Fil eName);
HIF.PostedFile. SaveAs(baseLoca tion + fn);
filesUploaded++ ;
status += fn + "<br>";
}
catch(Exception err)
{
lblError.Text = "Error saving file " + baseLocation
+ "<br>" + err.ToString();
}
}

if(filesUploade d == hif.Count)
{
lblError.Text = "These " + filesUploaded + " file(s) were "
+ "uploaded:< br>" + status;
}
hif.Clear();
lstAttachments. Items.Clear();
}
}

Hi!!!

I had a similar problem and i solve it using the following lines:
string folder = Path.GetDirecto ryName(path);
if(!Directory.E xists(folder))
{
try
{
Directory.Creat eDirectory(fold er);
}
catch(Exception ex)
{
EventLog.WriteE ntry("LogServic e", ex.Message,
EventLogEntryTy pe.Error);
}
}

I hope it solves your problem.

Newbie,

You should be able to get the directory in the filename using the static
GetDirectoryNam e method on the Path class. Then, you can pass that to the
static CreateDirectory method on the Directory class to create the directory
before you save the file.

Hope this helps.
