.NET String Literal File Path Error

Question

I have a filepath string defined like so:

string projectPath = @"G:\filepath\example\example\";

however when I debug:

projectPath = G:\\filepath\\example\\example\\

am I missing something? I thought the @ was for literal string's so I don't have to escape backslashes. If I try escaping

string projectPath = "G:\\filepath\\example\\example\\";

I get the same problem, any ideas?

EDIT: Apparently this is a non-issue, my code just happens to break where projectPath is used:

string [] folders = Directory.GetDirectories(projectPath);

I guess I have an incorrect path?

EDIT 2: the issue wasn't the string, it was an access denied on the folder I tried to access. Oops!

Can you tell us the text in the error? It could be an incorrect path. — B.K.

For future questions try to see if question is really scoped to what you trying to do - there is nothing special about file path - you could have asked more generic question about just strings... (but I see that it would be immediate duplicate instead of surviving for some time). — Alexei Levenkov

No, the debugger shows the extra backslashes but they are not actually there.So you don't need to be worry.

Oh, I see. The issue is my function breaks at the line where projectPath is used, so I assumed that was the problem.

Based on your edits and comments, I gather that you might benefit from using try{}catch(){} statements in your code. If it's an invalid IO operation, such an invalid path, you would be able to see it from the exception's message and avoid "crashes."

Example:

string projectPath = @"G:\filepath\example\example\";
string[] folders = null;

try
{
    folders = Directory.GetDirectories(projectPath);
}
catch(Exception e)
{
    Debug.WriteLine(e.Message);
}

You may also try Directory.Exists() method:

string projectPath = @"G:\filepath\example\example\";
string[] folders = null;

if (Directory.Exists(projectPath))
{
    folders = Directory.GetDirectories(projectPath);
}

Although, I prefer try{}catch(){}, just in case there's a permissions issue.
