c# "\" Unrecognized escape sequence *URGENT*

[dinoni]

Hello
I have problem in Visual Studio 2005 C# that I cannot resolve.
I have a path to my folder _putanja = @"images"; and I want
to save one file in my case image file let say image_name.jpg in this folder.
Now in new string I try to concatenate path with file (file will be in this folder) but when I try to concatenate like:

_fotka = textBox8.Text.Trim(); //this is where I enter name of picture
_slika = _putanja + @"\" + _fotka + ".jpg";

when I debug I get \\ instead of \ backslash
result is “slike\\image_name.jpg”, bit I want “slike\image_name.jpg” with just one backslash, because I will write this in DB and when I will read this string with 2 \\ I will get error!
Any help, what is wrong with my code.
Thanks

The simple explanation is the user has included a backslash in the textbox (e.g. "slike\").

To fix this, you could prevent the user from entering a path with a backslash, but you probably don't want to do this because then the user couldn't enter something like "slike\temp" as a path.

The proper way to do this is to check each component of the path prior to forming the whole path and strip off any unnecessary back slashes.

Fortunately, Path.Combine takes the drudgery out of doing this manually. There are several method overloads that allow you to combine two or more path components.

_slika = Path.Combine( _putanja, String.Format( "{0}.jpg", _fotka ) )";

In the above code, if _putanja contains a proper path, then <picture_name>.jpg will be appended to it.

On caveat to the above code is that it doesn't detect if a user enters the .jpg extension into the textbox. The code as written will happily append a second ".jpg" to the picture name even if one already exists. If this is a concern to you, then modify the code to ensure only one .jpg extension ever gets added.
