Path Format not Supported

[Jim McGivney]

In an aspx page I run the following C# code-behind:
string filename = null;
filename = txtUpload.PostedFile.FileName.Trim();
//save the file
txtUpload.PostedFile.SaveAs(@"C:\home\sites\bobo.com\web\" + filename);

I get the following error: The given path's format is not supported.

Any suggestions as to the proper format for the path would be appreciated.

Thanks,
Jim

Check the variable "filename". Name sure it contains what you expect and
nothing more. Also, see what happens if you remove the ".com" from the
path.

Hi Jim,

Looking at your code here my 5 cents :
your code : filename = txtUpload.PostedFile.FileName.Trim(); will return
the full filename
e.g c:\test\fileUploads\filetoupload.txt
hence file name = c:\test\fileUploads\filetoupload.txt

now when you do
txtUpload.PostedFile.SaveAs(@"C:\home\sites\bobo.com\web\" + filename)

you are doing (@"C:\home\sites\bobo.com\web\" +
"c:\test\fileUploads\filetoupload.txt")

hence it will try to save the file in the path :
C:\home\sites\bobo.com\web\c:\test\fileUploads\filetoupload.txt

which is invalid format coz of c:\ being twice and hence you getting the
invalid format error

Yuo should double the backslashes
ex: c:\\inetpub\\.....

When working with file names and paths it's recommended to use
System.IO.Path-class
For example:
string fName = System.IO.Path.GetFileName(filename) //gets only the file
name from full path
It's also recommended to use System.IO.Path.Combine() method to build paths.
So I would do it like:
txtUpload.PostedFile.SaveAs(Path.Combine(@"C:\home\sites\bobo.com\web",
Path.GetFileName(filename));

re:

Actually, no, because he's using the literal @ :

SaveAs(@"C:\home\sites\bobo.com\web\"

The @ means that he does *not* have to double the backslashes.

The correct answer was posted by Shaunak.

The code concatenates two full file paths,
and that is not acceptable as a path format.
