窗体和控件的大小整体变化 代码纠错
程序代码：using System;
using System.Collections.Generic;
using using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace winfomchange
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private float X; private float Y;
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;
con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
if (con.Controls.Count > 0)
{
setControls(newx, newy, con);
}
}
}
private 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 Form1_Load(object sender, EventArgs e)
{
this.Resize += new EventHandler(Form1_Resize);
X = this.Width;
Y = this.Height;
x = this.statusStrip1.Width;
y = this.statusStrip1.Height;
setTag(this);
}
}
}
代码出现 “未对对象引用实例”错误、、、、、不知道该怎么修改。。。
