Path.Combine is adding slashes to file path?

Question

See the code below. I'm not sure why the two extra // are appearing before the file extension or how to best handle?

string avatarFilePath = "~/_images/avatar/";
string userId = 53da95a1-cc48-42d0-9a00-167f47ce5933";
string avatarFileExt = ".png";

string path = Path.Combine(avatarFilePath, userId, avatarFileExt);

//value of 'path' is: "~/_images/avatar/53da95a1-cc48-42d0-9a00-167f47ce5933\\.png" <-- note two slashes before extension

`Path.Combine` combines Windows file paths, not URL or network paths. To combine network paths use [`new Uri`](http://stackoverflow.com/questions/372865/). — Dour High Arch, Dec 08 '16 at 21:16

Path.Combine is not intended to create file names or build urls. You should build the file name first, then use Uri to build your url. Something like

string avatarFilePath = "~/_images/avatar/";
string userId = 53da95a1-cc48-42d0-9a00-167f47ce5933";
string avatarFileExt = ".png";
string fileName = String.Format("{0}{1}", userId, avatarFileExt);
Uri uri = new Uri(avatarFilePath, fileName);
string url = uri.ToString();

if you want a physical file path you could go with

Server.MapPath(url);

Thank you, this worked perfectly! – PixelPaul Dec 08 '16 at 21:29 — PixelPaul, Dec 08 '16 at 21:29
