Display data from txt file to richtextbox

Question

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");
       }
   }
}
