这是一个我认为您想要的示例:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Resources;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication8
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
this.Icon = Properties.Resources.icon;
}
private void button2_Click(object sender, EventArgs e)
{
this.Icon = Properties.Resources.image;
}
private void button3_Click(object sender, EventArgs e)
{
this.Icon = Properties.Resources.ICO_Logo;
}
}
}
