C#窗体程序随电脑分辨率自动调整大小

添加类方法，代码如下：

        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)
            {
                try
                {
                    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);
                    }
                }
                catch
                {

                }
            }

窗体程序调用方法，代码如下：

#region 自动调整界面大小

        private float X;

        private float Y;

        private void Test_Load(object sender, EventArgs e)
        {
            this.Resize += new EventHandler(Test_Resize);

            X = this.Width;

            Y = this.Height;

            Autosize.setTag(this);

            Test_Resize(new object(), new EventArgs());

        }

        private void Test_Resize(object sender, EventArgs e)
        {
            if (X==0)
            {
                Test_Load(new object(), new EventArgs());
            }
            else
            {
                float newx = (this.Width) / X;

                float newy = this.Height / Y;

                Autosize.setControls(newx, newy, this);
            }
        }

        #endregion

在窗体程序初始化后面增加一次load的方法调用，如下图：
