when displaying, it should seperate the name and age, but it doesnt

Outputs:
   Jiin Taq 19

To keep the "\n" format when displaying text in a textbox, you can use the Environment.NewLine property instead of "\n" in your code. This property will insert a new line character that is appropriate for the current operating system.

For example, you could modify the ReadFile method in the following way:

public void ReadFile()
{
    TextReader reder = File.OpenText(@"C:\Users\Dat.txt");
    textBox1.Text = reder.ReadToEnd().Replace("\n", Environment.NewLine);
}

This will replace any "\n" characters in the text with the appropriate new line character for the current operating system, allowing the text to be displayed properly in the textbox.
