Access a file on local area network with authorization

Hi. Firstly, I apologize to you for my poor english.

I want to access a file on a different machine that is on the same network as me. I also need to authenticate when doing this.

For Example;

My Local IP : 10.1.1.138

Target Local IP: 10.1.1.235

File Location is \\10.1.1.235\FolderName\example.txt

Username for target machine is: "username"

Password for target machine is: "password"

I want to do like this:

string data = File.GetAllText(@"\\10.1.1.235\FolderName\example.txt"); //with authentication

How can I do?
