你好，



我在表单隐藏和显示期间遇到问题，问题是： - 当windows state属性设置为正常时，我的两个表单都打开了，当我们设置的属性是最大化的，所以代码运行正常，只有一个表单显示。

推荐答案

phil.o和Wes Aday说的是真的 - 你见证的行为是预期的。



但是，如果你限制每个表单的大小，然后您可以控制表单最大化时占用的桌面格局的大小。实现此目的的一种方法是重写OnSizeChanged事件处理程序。以下应用程序演示了此解决方案。

What phil.o and Wes Aday stated is true - the behavior you witness is expected.

However, if you limit the size of each form, then you can control how much of the desktop landscape the forms will occupy when they are maximized. One way you achieve this is by overriding the OnSizeChanged event handler. The following application demonstrates this solution.

using System;
using System.Windows.Forms;

namespace MaximizeWindowOverride
    {

    public partial class Form1 : Form
        {

        // ******************************************* class constants

        const int       MAXIMUM_HEIGHT = 500;
        const int       MAXIMUM_WIDTH = 600;

        // ******************************************* class variables

        FormWindowState current_window_state;

        // ***************************************************** Form1

        public Form1 ( )
            {

            InitializeComponent ( );

            current_window_state = this.WindowState;
            }

        // ********************************************* OnSizeChanged
        
        protected override void OnSizeChanged ( EventArgs e )
            {

            base.OnSizeChanged ( e );

            if ( ( this.WindowState == FormWindowState.Maximized ) &&
                 ( current_window_state != FormWindowState.Maximized ) )
                {
                this.Width = MAXIMUM_WIDTH;
                this.Height = MAXIMUM_HEIGHT;

                this.WindowState = FormWindowState.Normal;
                }

            current_window_state = this.WindowState;
            }

        } // class Form1

    } // namespace MaximizeWindowOverride

希望有所帮助。
