一,创建AutoSizeFormClass类
using System;
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApp15
{
public static class AutoSizeFormClass
{
public static float X;
public static float Y;
public static void setTag(Control cons)
{
foreach (Control con in cons.Controls)
{
con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
if (con.Controls.Count > 0)
setTag(con);
}
}
public static void setControls(float newx, float newy, Control cons)
{
foreach (Control con in cons.Controls)
{
string[] mytag = con.Tag.ToString().Split(new char[] { ':' });
float a = Convert.ToSingle(mytag[0]) * newx;
con.Width = (int)a;
a = Convert.ToSingle(mytag[1]) * newy;
con.Height = (int)(a);
a = Convert.ToSingle(mytag[2]) * newx;
con.Left = (int)(a);
a = Convert.ToSingle(mytag[3]) * newy;
con.Top = (int)(a);
Single currentSize = Convert.ToSingle(mytag[4]) * Math.Min(newx, newy);
con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
if (con.Controls.Count > 0)
{
setControls(newx, newy, con);
}
}
}
}}
二,MainFrom中添加：
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace WindowsFormsApp15
{
public partial class MainFrom : Form
{
public MainFrom()
{
InitializeComponent();
}
[DllImport("user32")]
private static extern int SendMessage(IntPtr hwnd, int wMsg, int wParam, IntPtr lParam);
private const int WM_SETREDRAW = 0xB;
private void MainFrom_Resize(object sender, EventArgs e)
{
SendMessage(this.Handle, WM_SETREDRAW, 0, IntPtr.Zero);
float newx = (this.Width) / AutoSizeFormClass.X;
float newy = this.Height / AutoSizeFormClass.Y;
AutoSizeFormClass.setControls(newx, newy, this);
SendMessage(this.Handle, WM_SETREDRAW, 1, IntPtr.Zero);
this.Invalidate(true);
}
private void MainFrom_Load(object sender, EventArgs e)
{
this.Resize += new EventHandler(Form1_Resize);
AutoSizeFormClass.X = this.Width;
AutoSizeFormClass.Y = this.Height;
AutoSizeFormClass.setTag(this);
Form1_Resize(new object(), new EventArgs());
}
}
}
