Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new Windows Forms Application in C# is created using Visual Studio 2017 with name "Demo_RandomNumberFileReader".This application contains a form with name "Form1.cs".Below are the files associated with form1.

1.Form1.cs[Design]

一口 Random Number File Reader × Click to Read File Exit

2.Form1.Designer.cs

namespace Demo_RandomNumberFileReader
{
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
