C#winform窗体如何通过windowApi的FindWindow函数获取窗体句柄

在同一个程序里，传统方式是通过this来设置当前窗体的最大化、最小化等操作，

那么怎样通过窗体句柄来设置窗体的最大化、最小化呢？

1、界面布局

通过this设置窗体最大化： name:btnWindowThis

通过handle设置窗体最大化：name:btnWindowHandle

2、设置窗体最大化

1）this方式

直接设置当前窗体的状态为最大化就可以了，

       /// <summary>

        /// 通过this设置方法

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void btnWindowThis_Click(object sender, EventArgs e)

        {

            //通过this.WindowState设置窗体最大化

            this.WindowState = FormWindowState.Maximized;

        }

2）handle方式

首先获取当前窗体的句柄，通过句柄控制窗体最大化

        /// <summary>

        /// 通过句柄设置方法

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void btnWindowHander_Click(object sender, EventArgs e)

        {

            // 获取查找窗体句柄(通过窗体标题名)

            IntPtr mainHandle = FindWindow(null, "演示窗体");

            if (mainHandle != IntPtr.Zero)

            {

                //通过句柄设置当前窗体最大化（0：隐藏窗体，1：默认窗体，2：最小化窗体，3：最大化窗体，....）

                bool result = ShowWindowAsync(mainHandle, );

            }

        }

Ps: 获取窗体句柄，也可以用C++的Spy++工具查看（获取到的句柄是16进制，而FindWindow()是获取10进制）
