双击Form_Closing事件，然后直接写以下代码，使得窗体无法关闭：private
void
Form_FormClosing(object
sender,
FormClosingEventArgs
e)
{
e.Cancel
=
true;
} C#中可没有直接屏蔽关闭按钮的方法，你硬要这样也可以：[System.Runtime.InteropServices.DllImport("user32.dll")]
static
extern
IntPtr
GetSystemMenu(IntPtr
hWnd,
bool
bRevert);
[System.Runtime.InteropServices.DllImport("user32.dll")]
static
extern
int
GetMenuItemCount(IntPtr
hMenu);
[System.Runtime.InteropServices.DllImport("user32.dll")]
static
extern
bool
DrawMenuBar(IntPtr
hWnd);
[System.Runtime.InteropServices.DllImport("user32.dll")]
static
extern
bool
RemoveMenu(IntPtr
hMenu,
uint
uPosition,
uint
uFlags);
protected
override
void
OnLoad(EventArgs
e)
{

base.OnLoad
(e);

const
Int32
MF_BYPOSITION
=
0x400;

const
Int32
MF_REMOVE
=
0x1000;

IntPtr
menu
=
GetSystemMenu(this.Handle,
false);

int
menuCount
=
GetMenuItemCount(menu);

if
(menuCount
>
1)

{

//删除菜单的「关闭」和分隔符

RemoveMenu(menu,
(uint)
(menuCount
-
1),
MF_BYPOSITION
|
MF_REMOVE);

RemoveMenu(menu,
(uint)
(menuCount
-
2),
MF_BYPOSITION
|
MF_REMOVE);

DrawMenuBar(this.Handle);

}
