在亮拆VS中新建一个Windows 窗体应用程序项目,然后从工具敬州枣箱中拖拽两个按钮和一个文本框到Form1窗体中,分别双击两个按钮之后(其实就是建立按钮迹烂点击事件),在代码中粘贴如下代码即可.
private void button1_Click(object sender, EventArgs e)
{
this.textBox1.BackColor = Color.Blue;
this.textBox1.TextAlign = HorizontalAlignment.Center;
this.textBox1.Text = "努力学习C#!";
}
private void button2_Click(object sender, EventArgs e)
{
this.textBox1.BackColor = Color.White;
this.textBox1.TextAlign = HorizontalAlignment.Left;
this.textBox1.ResetText();
}
private void button1_Click(object sender, EventArgs e)
{
this.textBox1.BackColor = Color.Blue;
this.textBox1.TextAlign = HorizontalAlignment.Center;
this.textBox1.Text = "努力学习C#!";
}
private void button2_Click(object sender, EventArgs e)
{
this.textBox1.BackColor = Color.White;
this.textBox1.TextAlign = HorizontalAlignment.Left;
this.textBox1.ResetText();
}

往窗体中添加一个 label 两个Button 控件
添加两个按钮的单击事件,如下:
private void button1_Click(object sender, EventArgs e)
{
label1.Visible = true;
label1.Text = "努力学习C#";
label1.BackColor = Color.Blue;/侍森枯/背景颜色为蓝老洞色
label1.Location = new Point(50, 50);/春族/位置
}
private void button2_Click(object sender, EventArgs e)
{
label1.Text = "";
label1.Visible = false;//隐藏
label1.BackColor = Color.White;
}
添加两个按钮的单击事件,如下:
private void button1_Click(object sender, EventArgs e)
{
label1.Visible = true;
label1.Text = "努力学习C#";
label1.BackColor = Color.Blue;/侍森枯/背景颜色为蓝老洞色
label1.Location = new Point(50, 50);/春族/位置
}
private void button2_Click(object sender, EventArgs e)
{
label1.Text = "";
label1.Visible = false;//隐藏
label1.BackColor = Color.White;
}
