如果你想保持你的窗体顶部与其他形式的在自己的应用大部分可以使用
MyForm.TopMost = true;
否则,如果你想保持你的应用程序在其他窗口的顶部,你有Windows操作系统调用Win32函数。下面是一个示例
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
static readonly IntPtr HWND_TOP = new IntPtr(0);
static readonly IntPtr HWND_BOTTOM = new IntPtr(1);
const UInt32 SWP_NOSIZE = 0x0001;
const UInt32 SWP_NOMOVE = 0x0002;
const UInt32 TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
SetWindowPos(this.Handle, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS);
}
}
}
