如何使WinForms应用程序全屏显示

this.WindowState = FormWindowState.Maximized;

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

public class FullScreenForm : Form
{
    [DllImport("user32.dll")]
    private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

    [DllImport("user32.dll")]
    private static extern int GetWindowLong(IntPtr hWnd, int nIndex);

    private const int GWL_STYLE = -16;
    private const int WS_SYSMENU = 0x80000;

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        // 隐藏任务栏
        int style = GetWindowLong(this.Handle, GWL_STYLE);
        SetWindowLong(this.Handle, GWL_STYLE, style & ~WS_SYSMENU);

        // 设置全屏
        this.WindowState = FormWindowState.Maximized;
        this.FormBorderStyle = FormBorderStyle.None;
        this.TopMost = true;
    }
}
