篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Visual Studio 2019 C#下WinForm窗体设计 & 凯撒，单码，乘法逆元对的GUI相关的知识，希望对你有一定的参考价值。
1、窗体和控件设计
-
GUI界面程序的创建和CUI界面类似，直接VS创建 C# windows 窗体应用即可。
-
创建后默认会有一个Program.cs和一个Form1窗体。
Program里决定了启动运行的窗体，Form1是系统自带的。
-
在菜单栏的项目里可以添加窗体
-
可以通过左边的工具箱为窗体添加控件，常用的有按钮，文本框，文字显示等。
右键属性可以更改控件的长宽高等设置。
双击控件会进入控件默认触发事件的程序编辑模式（当然也可以自己写别的）。
- 可以通过这两行代码实现在一个窗体中打开另一个窗体。
Form2 f2 = new Form2();
f2.ShowDialog();
2、凯撒，单码，乘法逆元的GUI实现
Program
using System;

namespace 古典加密系列
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.SetHighDpiMode(HighDpiMode.SystemAware);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
Form1

{
Form2 f2 = new Form2();
f2.ShowDialog();
}
private void button2_Click(object sender, EventArgs e)
{
Form3 f3 = new Form3();

Form4 f4 = new Form4();
f4.ShowDialog();
}
