C#控件随窗体大小自动调整

构造函数中：

            int count = this.Controls.Count * 2 + 2;
            float [] factor=new float [count];
            int i = 0;
            factor[i++] = Size.Width;
            factor[i++] = Size.Height;
            foreach (Control ctrl in this.Controls)
            {
                factor[i++] = ctrl.Location.X / (float)Size.Width;
                factor[i++] = ctrl.Location.Y / (float)Size.Height;
                ctrl.Tag = ctrl.Size;
            }
            Tag = factor;

为控件的TAG属性加入大小

Resize事件中自动调整大小

        private void Summary_Resize(object sender, EventArgs e)
        {
            float[] scale = (float[])Tag;
            int i = 2;
            foreach (Control ctrl in this.Controls)
            {
                ctrl.Left = (int)(Size.Width * scale[i++]);
                ctrl.Top = (int)(Size.Height * scale[i++]);
                ctrl.Width = (int)(Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width);
                ctrl.Height = (int)(Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height);
            }
        }
