C#窗体封闭

C#窗体关闭
请问大神们，这样之后怎么关闭窗体。。小弟刚搞这个，不是很会。求解ing。。

C# code

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace Dynamic{    public partial class Dynamic : Form    {        public Dynamic()        {            InitializeComponent();        }        int offset = 25;//垂直增量        int offset1 = 25;//水平增量        private void Dynamic_FormClosing(object sender, FormClosingEventArgs e)        {            timer_dynamic.Enabled = true;            e.Cancel = true;        }          private void timer_dynamic_Tick(object sender, EventArgs e)        {            this.Top += offset;            this.Height -= 70;            if (this.Top > 300)            {                offset = 0;                this.Left += offset1;                this.Width = -50;                if (this.Left > 600)                {                    offset1 = 0;                }            }        }    }}

[解决办法]
protected override void OnFormClosing(FormClosingEventArgs e)
{
base.OnFormClosing(e);
if (MessageBox.Show(this, "确定退出系统？", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)
{
this.Dispose();
GC.Collect();
Application.Exit();
}
else
{
e.Cancel = true;
}
}
[解决办法]

探讨

引用:

e.Cancel = true;去掉


e.Cancel = true;
是我为了捕获关闭事件。你可以测试下我的代码，我是想在实现那种效果之后在关闭。。

不知道你要执行动作之后自动关闭还是手动关闭？（应该是自动关闭吧）
（1）如果自动关闭，那么添加两个临时变量，用于检测何时关闭窗体。并在FormClosing事件中，将e.Cancel=true;改为根据timer的Enabled来调整。具体代码如下（具体变量名与你的不一样，自己改动）：

C# code

public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        int offset = 25;//垂直增量        int offset1 = 25;//水平增量        int tempHeight;        int tempWidth;        private void timer1_Tick(object sender, EventArgs e)        {            tempHeight=this.Height;            tempWidth=this.Width;            this.Top += offset;            this.Height -= 70;            if (this.Top > 300)            {                offset = 0;                this.Left += offset1;                this.Width -=50;                if (this.Left > 600)                {                    offset1 = 0;                }            }            if(this.Width==tempWidth&&this.Height==tempHeight)            {                this.Close();            }        }        private void Form1_FormClosing(object sender, FormClosingEventArgs e)        {            timer1.Enabled = !timer1.Enabled;            if (timer1.Enabled)            {                e.Cancel = true;            }        }    }

你在关闭事件中调用你写的要显示效果的方法不就行了嘛
  private void Dynamic_FormClosing(object sender, FormClosingEventArgs e)
{
  timer_dynamic.Enabled = true;
  timer_dynamic_Tick(null, null);
}
