vs2013 窗体应用编程—控件大小随窗体变化（通过代码实现）

namespace Example
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private float X; private float Y;
//获取控件的width、height、left、top、字体大小的值
//存放在控件的Tag属性中
private void setTag(Control cons)
{
//遍历窗体中的控件
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 SetTag(Control cons)
{
//遍历窗体中的控件
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);
}
}
}
//根据窗体大小调整控件大小
private void setControls(float newx, float newy, Control cons)
{
//遍历窗体中的控件，重新设置控件的值
foreach (Control con in cons.Controls)
{

string[] mytag = con.Tag.ToString().Split(new char[] { ':' });//获取控件的Tag属性值，并分割后存储字符串数组
float a = Convert.ToSingle(mytag[0]) * newx;//根据窗体缩放比例确定控件的值，宽度
con.Width = (int)a;//宽度
a = Convert.ToSingle(mytag[1]) * newy;//高度
con.Height = (int)(a);
a = Convert.ToSingle(mytag[2]) * newx;//左边距离
con.Left = (int)(a);
a = Convert.ToSingle(mytag[3]) * newy;//上边缘距离
con.Top = (int)(a);
Single currentSize = Convert.ToSingle(mytag[4]) * newy;//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)
{

float newx = (this.Width) / X; //窗体宽度缩放比例
float newy = this.Height / Y;//窗体高度缩放比例
setControls(newx, newy, this);//随窗体改变控件大小
this.Text = "witdth:"+this.Width.ToString() + " heighet:   " + this.Height.ToString();//窗体标题栏文本

}

private void Form1_Load(object sender, EventArgs e)
{
this.Resize += new EventHandler(Form1_Resize);//窗体调整大小时引发事件

X = this.Width;//获取窗体的宽度
Y = this.Height;//获取窗体的高度
setTag(this);//调用方法
}

}
}
