using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace WinFormsApp16 { public class student { private int stuno; private string stuname; private int stuage; private string stusex; private string stuspeciality; public student(int myno ,string myname, int myage ,string mysex,string myspecility) { this.Stuno = myno; this.Stuname = myname; this.Stuage = myage; this.Stusex = mysex; this.Stuspeciality = myspecility; } public int Stuno { get => stuno; } public string Stuname { get => stuname; } public string Stusex { get => stusex; } public string Stuspeciality { get => stuspeciality; set => stuspeciality = value; } public int Stuage { get => stuage; set => stuage = value; } } }把这段代码优化成输入信息后再只读

这段代码是 C# 语言的代码，可以通过在 Windows 系统上安装 Visual Studio 编辑器进行修改和运行。

以下是将该代码优化为输入信息后再只读的代码示例：

using System;
using System.Windows.Forms;

namespace WinFormsApp
{
    public partial class Form1 : Form
    {
        private int stuno;
        private string stuname;
        private int stuage;
        private string stusex;
        private string stuspeciality;

        public Form1()
        {
            InitializeComponent();
        }

        private void btnSubmit_Click(object sender, EventArgs e)
        {
            stuno = int.Parse(txtStuno.Text);
            stuname = txtStuname.Text;
            stuage = int.Parse(txtStuage.Text);
            stusex = txtStusex.Text;
            stuspeciality = txtStuspeciality.Text;

            // 显示信息
            txtInfo.Text = $"学号：{stuno}\r\n姓名：{stuname}\r\n年龄：{stuage}\r\n性别：{stusex}\r\n专业：{stuspeciality}";

            // 设置文本框只读
            txtStuno.ReadOnly = true;
            txtStuname.ReadOnly = true;
            txtStuage.ReadOnly = true;
            txtStusex.ReadOnly = true;
            txtStuspeciality.ReadOnly = true;
        }
    }
}

这段代码实现了一个简单的 Windows 窗体应用程序，包含了一个输入学生信息的表单，用户在填写完信息后，点击提交按钮，会将学生信息显示在一个文本框中，并将输入框设置为只读状态，不允许再次编辑。
