Failed to map the path '/'

I have an ASP.Net website solution in Visual Studio, and when trying to Server.MapPath(@"\");I receive the following error. I know this question has been asked before but I am yet to find a solution that has worked for me. Any ideas would be great.

Failed to map the path '/'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidOperationException: Failed to map the path '/'.

Line 10:     protected void Page_Load(object sender, EventArgs e)
Line 11:     {
Line 12:       string directory = Server.MapPath(@"\");
Line 13:       Response.Write(directory);

If all of the others suggested solution if not working it means that your Visual Studio doesn't have a administrative privileged.

Hence you may run the Visual Studio "Run as Administrator" and try to execute once again.

if none of the answers here How to solve error message: "Failed to map the path '/'." help, try Server.MapPath(@".\");. This and your code worked for me, and produced the same results.
