Create a file in the userfiles folder (C#, Windows Forms)

Question

I'm trying to create a text file in my Windows Forms application. It is working fine, but it is creating the text file in the application's default location (like in folder bin). But I want to save that created text file in my user files folder. How can I do it?

This is my code:

FileInfo fileusername = new FileInfo("userinfo.txt");
StreamWriter namewriter = fileusername.CreateText();
namewriter.Write(txtUsername.Text);
namewriter.Close();

Answer 1

You can use Environment.GetFolderPath to get the path to the user data folder:

string fileName = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
    "userinfo.txt");

Look into the documentation of the Environment.SpecialFolder enum in order to find the folder that best suits your needs.

Answer 2

You can use the Environment.GetFolderPath() function together with the Environment.SpecialFolder enumeration.

Use:

String filePath = Path.Combine(
    Evironment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
    "userinfo.txt");

to create the file name in the current users My Documents folder.

Answer 3

You can use Environment.SpecialFolder to create a filepath that points to my documents:

string filePath = System.IO.Path.Combine(Environment.SpecialFolder.ApplicationData.ToString(), "userinfo.txt");
