c#winform禁用關閉按鈕的方法

一、設定ControlBox為false
二、呼叫API實現了禁用關閉按鈕
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace winFormDemo
{
public partial class Form2 : Form
{
[DllImport("USER32.DLL")]
public static extern int GetSystemMenu(int hwnd, int bRevert);
[DllImport("USER32.DLL")]
public static extern int RemoveMenu(int hMenu, int nPosition, int wFlags);
const int MF_REMOVE = 0x1000;
const int SC_RESTORE = 0xF120; //還原
const int SC_MOVE = 0xF010; //移動
const int SC_SIZE = 0xF000; //大小
const int SC_MINIMIZE = 0xF020; //最小化
const int SC_MAXIMIZE = 0xF030; //最大化
const int SC_CLOSE = 0xF060; //關閉
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
int hMenu = GetSystemMenu(this.Handle.ToInt32(), 0);
RemoveMenu(hMenu, SC_CLOSE, MF_REMOVE);
}
}
}
