Winform 控件随窗体大小改变而变化

有如下3种方法：

方法1

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace MarkPrinter

{

public partial class ResizeTest : Form

{

public float X;

public float Y;

public float y;

public ResizeTest()

{

InitializeComponent();

}

private 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);

}

}

private 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]) * newy;

//改变字体大小

con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);

if (con.Controls.Count > 0)

{

setControls(newx, newy, con);

}

}

}

void Form1_Resize(object sender, EventArgs e)

{

// throw new Exception("The method or operation is not implemented.");

float newx = (this.Width) / X;

// float newy = (this.Height - this.statusStrip1.Height) / (Y - y);

float newy = this.Height / Y;

setControls(newx, newy, this);

this.Text = this.Width.ToString() + " " + this.Height.ToString();

}

private void ResizeTest_Load(object sender, EventArgs e)

{

this.Resize += new EventHandler(Form1_Resize);

X = this.Width;

Y = this.Height;

y = this.statusStrip1.Height;

setTag(this);

}

}

}

方法2

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace MarkPrinter

{

public partial class ResizeTest : Form

{

public float X;

public float Y;

public float y;

public ResizeTest()

{

InitializeComponent();

}

private void ResizeTest_Load(object sender, EventArgs e)

{

AutoScale(this);

}

/// <summary>

/// 控件随窗体自动缩放

/// </summary>

/// <param name="frm"></param>

public static void AutoScale(Form frm)

{

frm.Tag = frm.Width.ToString() + "," + frm.Height.ToString();

frm.SizeChanged += new EventHandler(frm_SizeChanged);

}

static void frm_SizeChanged(object sender, EventArgs e)

{

string[] tmp = ((Form)sender).Tag.ToString().Split(',');

float width = (float)((Form)sender).Width / (float)Convert.ToInt16(tmp[0]);

float heigth = (float)((Form)sender).Height / (float)Convert.ToInt16(tmp[1]);

((Form)sender).Tag = ((Form)sender).Width.ToString() + "," + ((Form)sender).Height;

foreach (Control control in ((Form)sender).Controls)

{

control.Scale(new SizeF(width, heigth));

}

}

}

}

用此方法时，如果界面一开始就要求最大化，在最大化之前就要调用AutoScale方法

方法3

将控件放进容器中， 然后使用控件的Dock属性来获取或设置控件停靠到父容器的哪一个边缘。(略)
