Solution 1

Because, inside a string literal, the backslash must be escaped, that is you write

C#

string path = "ADMIN\\SQLEXPRESS";

to assign ADMIN\SQLEXPRESS to variable path. See "Escape Sequences" at MSDN[^]

Is it me or you did not escape the backslash in your example? :)

You said: "when i am executing in debug mode"
That sounds like the issue is when you are looking at the value in the debugger.
If that is the case, then there is no actual problem, it is just that the debugger adds the extra backslash when it is displaying the string value.

So if you have a string that actually contains: ADMIN\SQLEXPRESS
The debugger will display this as: ADMIN\\SQLEXPRESS
