Error when create a folder by code

Question

I have a Member Register aspx page.

ACCOUNT(user,pass,mail,privilege)

When a user is registerd sucessfully, if the privilege == "lecturer" --> a folder is created which folder's name= user.

Take a look at my code below:

 if(privilege=="lecturer")
        {
            string path = this.Server.MapPath("~/Lecturer/"); // path="D:\\C#Projects\\website\\Lecturer\\"
            string targetPath = path + @"\";           
            System.IO.Directory.CreateDirectory(Server.MapPath(targetPath+newuser));

        }

It has an error: 'D:/C#Projects/website/Lecturer/david' is a physical path, but a virtual path was expected. Why???

I really want to create a david folder in Lecturer folder. Help???

You're calling MapPath twice. stackoverflow.com/questions/5039725/… stackoverflow.com/questions/8171275/… — taha ahmed

You do not need to use Server.MapPath again as you have already converted the virtual path to physical path.

Change

 System.IO.Directory.CreateDirectory(Server.MapPath(targetPath+newuser));

To

 System.IO.Directory.CreateDirectory(targetPath+newuser);

If you already have a physical path D:\\C#Projects\\website\\Lecturer\\, it doesn't make sense to call Server.MapPath

You can try this:-

var files = Directory.GetFiles(@"D:\C#Projects\website\Lecturer");

or simply try this:-

System.IO.Directory.CreateDirectory(targetPath+newuser);
