本文实例讲述了C#透明窗体实现方法。分享给大家供大家参考。具体实现方法如下：

namespace WindowsApplication1
{
  public partial class Form2 : Form
  {
    public Form2()
    {
      InitializeComponent();
      this.Opacity = 1;
      this.Text = "opacity=1";
      this.TopMost = true;
    }
    private void Form2_Activated(object sender, EventArgs e)
    {
      this.timer1.Enabled = true;
    }
    private void Form2_Deactivate(object sender, EventArgs e)
    {
      this.timer1.Enabled = false;
      this.Opacity = 1;
      this.Text = "opacity=" + this.Opacity.ToString();
    }
    private void Form2_Load(object sender, EventArgs e)
    {
    }
    private void timer1_Tick(object sender, EventArgs e)
    {
      if (this.Opacity > 0)
      {
        this.Opacity -= 0.1;
        this.Text = "opacity=" + this.Opacity.ToString();
      }
      else if (this.Opacity == 0)
      {
        this.Close();
      }
      else this.timer1.Enabled = false;
    }
  }
}

希望本文所述对大家的C#程序设计有所帮助。
