Writing a text file to the file system

[cwbp15]

Using Visual Studio C#

When I ran the following code:

System.IO;

private void Button1_Click(object sender, System.EventArgs e)
{
//FileStream fs = File.Create(Server.MapPath("test.txt"));
FileStream fs = File.Create("C:\\MYSAVEDFILES\\test.txt");
StreamWriter sw = new StreamWriter(fs);
sw.Write(TextBox1.Text);
sw.Close();
fs.Close();

}

I initially got an error message that "access was denied." The message
suggested that I give ASP.NET user access rights/permissions to the folder.

I then [manually] gave the logged in user write permission to the folder.

Then, when I ran the above code, the text file was created.

Is there another way [i.e., programatically using C#] to allow my code to
write a text file to the file system without giving access rights to a user?
Can the permissions be given to the app [the code] instead of to a user?

Any suggestions would be appreciated.

Thanks.

Yes, you can use impersonation.

For example, you can add a line similar to this to your web.config file:
<identity impersonate="true" userName="domain\MyUserName">
password="password"/>

Here's more info on impersonation:

That helped. Thanks Steve.

I noticed the password for my currently logged in user is in clear text when
using impersonation.

Added this line to the Application's web.config file

<identity impersonate="true" userName="username" password="password"/>

Wondering if there's a way to use impersonation and have the password
encrypted or placed elsewhere.

Thanks for the information on encrypting the passwords.

I've never tried DPAPI before.

This will work and u don't need to give permissions to any folder!!!

string strFilePath = "C:\\Test.txt";
FileStream fs = new FileStream(strFilePath,FileMode.Append);
StreamWriter sw = new
StreamWriter(fs,System.Text.Encoding.Default);
sw.Write("Shiva Test");
sw.Close();
