引言

C#作为一种强大的编程语言，在图形界面开发领域有着广泛的应用。通过C#，开发者可以轻松地创建出功能丰富、界面美观的应用程序。本文将为您详细介绍C#图形界面开发的实战案例，帮助您快速掌握相关技能。

一、C#图形界面开发基础

1.1 窗体设计

在C#中，窗体是图形界面开发的基础。以下是一个简单的窗体设计示例：

using System;
using System.Windows.Forms;
public class MyForm : Form
{ public MyForm() { this.Text = "我的窗体"; this.Size = new System.Drawing.Size(400, 300); this.Controls.Add(new Button { Text = "点击我", Location = new System.Drawing.Point(100, 100) }); } [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MyForm()); }
}

1.2 控件使用

在窗体中，我们可以使用各种控件来实现不同的功能。以下是一些常用的控件：

• 按钮（Button）：用于触发事件。
• 文本框（TextBox）：用于输入和显示文本。
• 标签（Label）：用于显示文本信息。
• 单选按钮（RadioButton）：用于单选操作。
• 复选框（CheckBox）：用于多选操作。

二、实战案例一：计算器

以下是一个简单的计算器实现：

using System;
using System.Windows.Forms;
public class CalculatorForm : Form
{ private TextBox textBox; private Button buttonAdd, buttonSub, buttonMul, buttonDiv; public CalculatorForm() { this.Text = "计算器"; this.Size = new System.Drawing.Size(300, 200); textBox = new TextBox { Location = new System.Drawing.Point(10, 10), Width = 280 }; buttonAdd = new Button { Text = "+", Location = new System.Drawing.Point(10, 40), Width = 60 }; buttonSub = new Button { Text = "-", Location = new System.Drawing.Point(80, 40), Width = 60 }; buttonMul = new Button { Text = "*", Location = new System.Drawing.Point(150, 40), Width = 60 }; buttonDiv = new Button { Text = "/", Location = new System.Drawing.Point(220, 40), Width = 60 }; buttonAdd.Click += Button_Click; buttonSub.Click += Button_Click; buttonMul.Click += Button_Click; buttonDiv.Click += Button_Click; this.Controls.Add(textBox); this.Controls.Add(buttonAdd); this.Controls.Add(buttonSub); this.Controls.Add(buttonMul); this.Controls.Add(buttonDiv); } private void Button_Click(object sender, EventArgs e) { string text = textBox.Text; double result = 0; double number1 = double.Parse(text.Split(' ')[0]); double number2 = double.Parse(text.Split(' ')[2]); switch (((Button)sender).Text) { case "+": result = number1 + number2; break; case "-": result = number1 - number2; break; case "*": result = number1 * number2; break; case "/": result = number1 / number2; break; } textBox.Text = text + " = " + result; } [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new CalculatorForm()); }
}

三、实战案例二：学生信息管理系统

以下是一个简单的学生信息管理系统实现：

using System;
using System.Collections.Generic;
using System.Windows.Forms;
public class StudentInfoForm : Form
{ private TextBox textBoxName, textBoxAge; private Button buttonAdd, buttonRemove, buttonList; private List students; public StudentInfoForm() { this.Text = "学生信息管理系统"; this.Size = new System.Drawing.Size(400, 300); textBoxName = new TextBox { Location = new System.Drawing.Point(10, 10), Width = 150 }; textBoxAge = new TextBox { Location = new System.Drawing.Point(170, 10), Width = 100 }; buttonAdd = new Button { Text = "添加", Location = new System.Drawing.Point(280, 10), Width = 60 }; buttonRemove = new Button { Text = "移除", Location = new System.Drawing.Point(10, 40), Width = 60 }; buttonList = new Button { Text = "列表", Location = new System.Drawing.Point(80, 40), Width = 60 }; students = new List(); buttonAdd.Click += Button_Click; buttonRemove.Click += Button_Click; buttonList.Click += Button_Click; this.Controls.Add(textBoxName); this.Controls.Add(textBoxAge); this.Controls.Add(buttonAdd); this.Controls.Add(buttonRemove); this.Controls.Add(buttonList); } private void Button_Click(object sender, EventArgs e) { switch (((Button)sender).Text) { case "添加": students.Add(new Student { Name = textBoxName.Text, Age = int.Parse(textBoxAge.Text) }); textBoxName.Clear(); textBoxAge.Clear(); break; case "移除": students.RemoveAt(0); break; case "列表": foreach (var student in students) { MessageBox.Show($"姓名：{student.Name}，年龄：{student.Age}"); } break; } } [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new StudentInfoForm()); }
}
public class Student
{ public string Name { get; set; } public int Age { get; set; }
}
