一、.实现弹窗淡入淡出等效果即弹窗自动关闭
技术要点：
1.弹窗效果（淡入淡出，自下而上滑入）使用WIN API实现
2.弹出的窗体在一定时间后，自动关闭使用一个timer实现，弹窗开始是，打开timer，到设置时间后，触发timer关闭窗体
代码：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Media; using System.Runtime.InteropServices; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace test007 { public partial class Message : Form { public Message() { InitializeComponent(); }
[DllImport("user32")] private static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags); //下面是可用的常量，根据不同的动画效果声明自己需要的 private const int AW_HOR_POSITIVE = 0x0001;//自左向右显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志 private const int AW_HOR_NEGATIVE = 0x0002;//自右向左显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志 private const int AW_VER_POSITIVE = 0x0004;//自顶向下显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志 private const int AW_VER_NEGATIVE = 0x0008;//自下向上显示窗口，该标志可以在滚动动画和滑动动画中使用。使用AW_CENTER标志时忽略该标志该标志 private const int AW_CENTER = 0x0010;//若使用了AW_HIDE标志，则使窗口向内重叠；否则向外扩展 private const int AW_HIDE = 0x10000;//隐藏窗口 private const int AW_ACTIVE = 0x20000;//激活窗口，在使用了AW_HIDE标志后不要使用这个标志 private const int AW_SLIDE = 0x40000;//使用滑动类型动画效果，默认为滚动动画类型，当使用AW_CENTER标志时，这个标志就被忽略 private const int AW_BLEND = 0x80000;//使用淡入淡出效果 private void Message_Load(object sender, EventArgs e) {
timer1.Enabled = true;
//弹窗 int x = Screen.PrimaryScreen.WorkingArea.Right - this.Width; int y = Screen.PrimaryScreen.WorkingArea.Bottom - this.Height; this.Location = new Point(x, y); //自下而上弹出窗体 AnimateWindow(this.Handle, 3000, AW_SLIDE | AW_ACTIVE | AW_VER_NEGATIVE); } private void timer1_Tick(object sender, EventArgs e) { //关闭窗体，淡入淡出 AnimateWindow(this.Handle, 1000, AW_BLEND | AW_HIDE);this.Close(); timer1.Enabled = false;
this.Close();
this.Dispose(); } } }
二、连接数据库
技术要点：
1.连接数据库需要使用Oracle.ManagedDataAccess.dll，具体如何安装，请看前面的文章
2.使用App.config文件来存放数据库连接字符串，方便后面更改
3.OracleHelper辅助类
代码：
App.config
<?xml version="1.0" encoding="utf-8"?> <configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> </startup> <appSettings> <add key="ConnectionStringSMTP" value="User id=XXX;password=XXX;Data Source=XXX.XXX.XXX.XXX:XXXX/XXX" /> </appSettings> </configuration>
获取配置代码
public static string connstrSMTP = ConfigurationManager.AppSettings["ConnectionStringSMTP"];
OracleHelper.cs
using Oracle.ManagedDataAccess.Client; using System; using System.Collections.Generic; using System.Configuration; using System.Data; using System.Linq; using System.Text; using System.Threading.Tasks; namespace test007 { public static class OracleHelper { public static string connstrSMTP = ConfigurationManager.AppSettings["ConnectionStringSMTP"]; public static string connstrTest = ConfigurationManager.AppSettings["ConnectionStringTest"];

三、最小化到托盘

四、弹窗在所有窗体最前
技术要点：
使用窗体的TopMost属性
代码：
