I want to write a text file in c#... but it is giving error

Access to the path 'C:\Program Files(x86)\Anil\demoSettings.txt' is denied.

string executableLocation = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string FileName = Path.Combine(executableLocation, "demoSettings.txt");
var permissionSet = new PermissionSet(PermissionState.None);
var writePermission = new FileIOPermission(FileIOPermissionAccess.Write, FileName);
permissionSet.AddPermission(writePermission);
if (permissionSet.IsSubsetOf(AppDomain.CurrentDomain.PermissionSet))
{
using (FileStream fstream = new FileStream(FileName, FileMode.Create))
using (TextWriter sw = new StreamWriter(fstream))
{
sw.WriteLine("Name," + "Anil");
sw.WriteLine("Code," + "C#");
}
}

how to fix this ??? can anyone help me out???

Change path:

From: C:\Program Files(x86)\Anil\demoSettings.txt

To: C:\Users\\Documents\demoSettings.txt

I think its hanging up because you are attempting to make change to the root folder for program installation. Its treated like a system folder where admin rights must be used to make changes.

However you should be able to write files to your user document folder without issues because when you log in, you gain immediate read and write permission access to that folder structure. Windows makes this your own space seperate from any other user and system folders.

This is my file location : @Nitin Sontakke

C:\Program Files (x86)\Anil\demoSettings.txt ,

I changed to string executableLocation = AppDomain.CurrentDomain.BaseDirectory; but then also same error ....

This file should create automatically @Bhairab Dutt , i can not set permission every time to that file, i want to give the permission when the file will create...

Note: But when i run with Run as administrator then their is no error....

Any other way to fix this ????

Hi anilananda,

I think when you add the permission to text file then the problem will solved .
Right click on textfile set the permission of Write ,Read etc by Properties .

Hope its help you.
Thanks.

Are you sure about the executableLocation? Can you please try modifying it as follows?
string executableLocation = AppDomain.CurrentDomain.BaseDirectory;

Hi Anilananda,

when your file is in C drive then you have to run .exe

-

by right click and *Run as administrator*

after it will not give error
