WinForm实现窗体最大化并遮盖任务栏的方法

本文实例讲述了WinForm实现窗体最大化并遮盖任务栏的方法。分享给大家供大家参考。具体实现方法如下：

using System;
using System.Windows.Forms;
using System.Drawing;
namespace CSImageFullScreenSlideShow
{
public class FullScreen
{
 private FormWindowState winState;
 private FormBorderStyle brdStyle;
 private bool topMost;
 private Rectangle bounds;
 public FullScreen()
 {
  IsFullScreen = false;
 }
 public bool IsFullScreen
 {
  get;
  set;
 }
 public void EnterFullScreen(Form targetForm)
 {
  if (!IsFullScreen)
  {
   Save(targetForm); // Save the original form state.
   targetForm.WindowState = FormWindowState.Maximized;
   targetForm.FormBorderStyle = FormBorderStyle.None;
   targetForm.TopMost = true;
   targetForm.Bounds = Screen.GetBounds(targetForm);
   IsFullScreen = true;
  }
 }
 /// <summary>
 /// Save the current Window state.
 /// </summary>
 private void Save(Form targetForm)
 {
  winState = targetForm.WindowState;
  brdStyle = targetForm.FormBorderStyle;
  topMost = targetForm.TopMost;
  bounds = targetForm.Bounds;
 }
 /// <summary>
 /// Leave the full screen mode and restore the original window state.
 /// </summary>
 public void LeaveFullScreen(Form targetForm)
 {
  if (IsFullScreen)
  {
   // Restore the original Window state.
   targetForm.WindowState = winState;
   targetForm.FormBorderStyle = brdStyle;
   targetForm.TopMost = topMost;
   targetForm.Bounds = bounds;
   IsFullScreen = false;
  }
 }
}
}

调用：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace CSImageFullScreenSlideShow
{
public partial class Test : Form
{
 public Test()
 {
  InitializeComponent();
  }
 private FullScreen fullScreen = new FullScreen();
 private void button1_Click(object sender, EventArgs e)
 {
  if (fullScreen.IsFullScreen)
  {
   fullScreen.LeaveFullScreen(this);
  }
  else
  {
   fullScreen.EnterFullScreen(this);
  }
 }
}
}

希望本文所述对大家的C#程序设计有所帮助。
