The SaveAs method is configured to require a rooted path, and the path 'fp' is not rooted

Question

I am doing Image uploader in Asp.net and I am giving following code under my controls:

    string st;
    st = tt.PostedFile.FileName;
    Int32 a;
    a =          


        

Answer 1

We cannot use the "SaveAs" method to write directly to an FTP server. Only local paths and UNC paths are supported for the above method.

To save it to FTP, please use the FtpWebRequest class.

Answer 2

I encountered the same problem. The problem is that you did not specify the path of the server that you want the file to be saved. And here is a probably simpler answer:

string fileName = tt.PostedFile.FileName;
string savePath = Server.MapPath("Path/Of/The/Folder/Comes/Here/") + fileName);
tt.PostedFile.SaveAs(savePath);

Answer 3

When reading the title of the question, I was thinking that it looked like you had put quotation marks around the variable name. Not really believing that it was so, I opened the question to read it, but it really was so...

Answer 4

If you want to save the uploaded file to the value of fp, just pass it in, don't put it in quotes:

tt.PostedFile.SaveAs(fp);

Answer 5

I suspect the problem is that you're using the string "fp" instead of the variable fp. Here's the fixed code, also made (IMO) more readable:

string filename = tt.PostedFile.FileName;
int lastSlash = filename.LastIndexOf("\\");
string trailingPath = filename.Substring(lastSlash + 1);
string fullPath = Server.MapPath(" ") + "\\" + trailingPath;
tt.PostedFile.SaveAs(fullPath);

You should also consider changing the penultimate line to:

string fullPath = Path.Combine(Server.MapPath(" "), trailingPath);

You might also want to consider what would happen if the posted file used / instead of \ in the filename... such as if it's being posted from Linux. In fact, you could change the whole of the first three lines to:

string trailingPath = Path.GetFileName(tt.PostedFile.FileName));

Combining these, we'd get:

string trailingPath = Path.GetFileName(tt.PostedFile.FileName));
string fullPath = Path.Combine(Server.MapPath(" "), trailingPath);
tt.PostedFile.SaveAs(fullPath);

Much cleaner, IMO :)

Answer 6

Use Server.MapPath():

fileUploader.SaveAs(Server.MapPath("~/Images/")+"file.jpg");
