WinForm进入全屏模式

本文关键字：模式 WinForm | 更新日期: 2023-09-27 18:34:26

我有WinForm应用程序，我想进入全屏模式并删除所有栏和任务栏。我用这个做到了：

this.WindowState = FormWindowState.Maximized;
this.FormBorderStyle = FormBorderStyle.None;
this.TopMost = true;

顶部栏确实隐藏了，但Windows TaskBar仍然可见。知道会有什么麻烦吗？

WinForm进入全屏模式

全屏运行您可以使用此方法。 

private void Form1_Load(object sender, EventArgs e)
{
    this.TopMost = true;
    this.FormBorderStyle = FormBorderStyle.None;
    this.WindowState = FormWindowState.Maximized;
}

要隐藏TaskBar只需将此类添加到您的项目中，.it 即可按预期工作。

using System;
using System.Runtime.InteropServices;
public class Taskbar
{
    [DllImport("user32.dll")]
    private static extern int FindWindow(string className, string windowText);
    [DllImport("user32.dll")]
    private static extern int ShowWindow(int hwnd, int command);
    [DllImport("user32.dll")]
    public static extern int FindWindowEx(int parentHandle, int childAfter, string className, int windowTitle);
    [DllImport("user32.dll")]
    private static extern int GetDesktopWindow();
    private const int SW_HIDE = 0;
    private const int SW_SHOW = 1;
    protected static int Handle
    {
        get
        {
            return FindWindow("Shell_TrayWnd", "");
        }
    }
    protected static int HandleOfStartButton
    {
        get
        {
            int handleOfDesktop = GetDesktopWindow();
            int handleOfStartButton = FindWindowEx(handleOfDesktop, 0, "button", 0);
            return handleOfStartButton;
        }
    }
    private Taskbar()
    {
        // hide ctor
    }
    public static void Show()
    {
        ShowWindow(Handle, SW_SHOW);
        ShowWindow(HandleOfStartButton, SW_SHOW);
    }
    public static void Hide()
    {
        ShowWindow(Handle, SW_HIDE);
        ShowWindow(HandleOfStartButton, SW_HIDE);
    }
}

用法：

Taskbar.Hide();

重新排序行以最大化表单之后将使用 FormBorderStyle.None 和 TopMost 标记

this.FormBorderStyle = FormBorderStyle.None;
this.TopMost = true;
this.WindowState = FormWindowState.Maximized;

您需要对语句重新排序，请尝试：

    this.TopMost = true;
    this.FormBorderStyle = FormBorderStyle.None;
    this.WindowState = FormWindowState.Maximized;
