C# Syntax Error

richard smith

I get a compile error of Newline in constant, but I don't see any issue with the code...can someone please point it out?

if (File.Exists(@"C:\Excel\Excel2010\Reports\" + workbookName[i] + "CompletedFiles\" + userName + ".xls"))

and my code highlights the ".xls" and gives a compile error of Newline in Constant. What is my issue?

Accepted answer
The reason for the original error is that in C# a backslash is regarded as being part of an 'escape sequence' such as \n, \r, \t etc. unless:

1. It's a 'verbatim' string preceded by @.

2. The backslash is doubled.

In these two cases it's regarded as an actual backslash.

So, doubling the backslash solved the problem :)

Disregard my post...I don't understand why, but adding double "\\" fixed it

if (File.Exists(@"C:\\Excel\\Excel2010\\Reports\\" + workbookName[i] + "CompletedFiles\\" + userName + ".xls"))
