C# IO.File.ReadAllBytes Path Problems

I'm new here at this forum. I have a C# Problem with System.IO.File.ReadAllBytes(). I read a filepath from a textbox like this C:\Users\Janek\Pictures\testpicture.

spath = tb_path.text;

System.IO.File.ReadAllBytes(spath);

But that doesnt work. VisualStudio says that's a wrong path format. How can iI build a working path?.

spath = "@" + tb_path.text;

System.IO.File.ReadAllBytes(path);

Didn't worked for me. It is certainly easy, but no matter what I try it does not work. But I think someone can help me here. Thanks for help!

Your code appears OK. The problem can be in the data you enter into the textbox instead. "C:\Users\Janek\Pictures\testpicture" can be a valid file name. but most likely it isn't, and you are missing a file extension. Something like

C:\Users\Janek\Pictures\testpicture.jpg

or

C:\Users\Janek\Pictures\testpicture.bmp

or

C:\Users\Janek\Pictures\testpicture.png

or whatever you file type is, is more likely to be correct.

Don't add "@" to the string, add it on the outside?

string path = tb_path.Text;

var x = File.ReadAllBytes(@path);

You want to escape like this : (@"C:\") not ("@C:\")
