C# Button点击变颜色

来源:百度知道 编辑:UC知道 时间:2024/06/28 06:04:17
在窗体上加一个按钮Button1,当启动调试时显示的是蓝色的“在线”,再点一下显示的是红色的“离线”,如此反复。请问代码该怎么写?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
public partial class Form1 : Form
{
Boolean isTrue = true;
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
if(isTrue)
{
this.button1.Text = "在线";
this.button1.ForeColor = Color.Blue;
}
else
{
this.button1.Text = "离线";
this.button1.ForeColor = Color.Red;
}
isTrue = !isTrue;
}
}
}

if(this.button1.Text=="离线")
