Display data from txt file to richtextbox

I want to be able to display data from .txt file up into a richtextbox.

This is the code I have at the moment:

private void getDetails()
{
string Path = $@"Z:\IT\Shares\PC\DA-0123\SD\SDD\DataFile.txt";
if (File.Exists(Path))
{
var data = File
.ReadAllLines(Path)
.Select(x => x.Split('='))
.Where(x => x.Length > 1)
.ToDictionary(x => x[0].Trim(), x => x[1]);
using (StreamWriter tw = File.AppendText($@"Z:\IT\Shares\PC\DA-0123\SD\Files\SysLog.txt"))
{
//I want this data being displayed in richTextBox
tw.WriteLine("Details..\n");
tw.WriteLine("Name: {0}", data["Name"]);
tw.WriteLine("Emp ID: {0}", data["Emp ID"]);
tw.WriteLine("---------------------------------------------\n");
}
}
}
