Relative path to txt in ASP

Question

Good afternoon, I am generating a file with Asp net the function saved in the hard drive if I put the path, however this file will be saved in a server and I’m having difficulty to put the relative path of where this file will be saved, I don’t know if I’m using the right function because I’m new.

function I’m using:

 string[] lines = {ENAME, FNAME,LNAME };
        System.IO.File.WriteAllLines(@"~/WriteLines.csv", lines);

error generated:

Details of Exception§System.IO.Directorynotfoundexception: Unable to locate a part of the path 'C: Program Files (x86) IIS Express ~ Writelines.csv'.

Answer 1

To get the relative path, you can use this form:

 string[] lines = {ENAME, FNAME,LNAME };
        System.IO.File.WriteAllLines(Server.MapPath("~/WriteLines.csv"), lines);

So just concatenate with your code.

The Server.Mappath code maps to the corresponding physical directory.

Answer 2

Use the function Server.MapPath("~/WriteLines.csv"). Would look like this:

string[] lines = {ENAME, FNAME,LNAME };
System.IO.File.WriteAllLines(Server.MapPath("~/WriteLines.csv"), lines);
