关于C# 开发Winfrom事后总结

一：要求能读取文件夹中视频及图片并判断

 private void Form1_Load(object sender, EventArgs e){string foldPath = "路径";//获取该目录下的文件 string[] files = Directory.GetFiles(@foldPath + "\\", "*.*", System.IO.SearchOption.TopDirectoryOnly);var th = new Thread(delegate (){//遍历每个文件for (int i = 0; i < files.Length; i++){//判断当前组文件中第i个文件if (IsPicture(files[i]))  //图片{Bitmap picture = new Bitmap(files[i]);ChangeBringToFrontImage(picture);}if (IsVideo(files[i]))    //视频{ChangeBringToFrontVideo(files[i]);}if (i == files.Length - 1){//从0开始重新播放i = 0;}}});
//开辟新线程
//th.IsBackground = true;
//th.Start();}
//定义判断是否为图片
public bool IsPicture(string filePath)
{var extension = Path.GetExtension(filePath).ToLowerInvariant();return extension == ".jpg" ||extension == ".jpeg" ||extension == ".png" ||extension == ".gif" ||extension == ".bmp" ||extension == ".tiff" ||extension == ".ico";}//定义判断是否为视频
public bool IsVideo(string filePath)
{var extension = Path.GetExtension(filePath).ToLowerInvariant();return extension == ".wmv" ||extension == ".asf" ||extension == ".asx" ||extension == ".avi" ||extension == ".mp4" ||extension == ".mov" ||extension == ".mkv";
}

二：视频跟图片要等比例放大缩小

pictureBox1.Dock = DockStyle.Fill;
axWindowsMediaPlayer1.Dock = DockStyle.Fill;

三：更换窗体运行图标

// 移除窗体边框
this.FormBorderStyle = FormBorderStyle.None;// 允许用户调整窗体大小
this.SizeGripStyle = SizeGripStyle.Show;//设置窗体的最大大小和最小大小
this.MaximumSize = new Size(1920, 1080);
this.MinimumSize = new Size(400, 300);//设置窗体的开始位置（CenterScreen将窗体居中）
this.StartPosition = FormStartPosition.CenterScreen;// 设置窗体的举头文本
this.Text = "Trs宣传播报";// 设置窗体的背景色
//this.BackColor = Color.Lime;// 设置窗体50%的透明度
//this.Opacity = 0.5;//更改窗体图标
this.Icon = Resources.Trs;

四：要求可配置文件路径及更换时间

//config<appSettings><add key="Time" value="4000" /><!--循环的时间--><add key="FromPath" value="C:\Users\N01465\Desktop\1" /><!--播放路径--></appSettings>//From1_cs// 强制重新加载app.configConfigurationManager.RefreshSection("appSettings");// 读取所有设置Time     = ConfigurationManager.AppSettings["Time"];FromPath = ConfigurationManager.AppSettings["FromPath"];

五：运行渲染的过程中不运行卡顿

//如一 开启新线程不使用主线程去渲染
private void ChangeBringToFrontImage(Image img)
{if (pictureBox1.InvokeRequired){// 使用Invoke安全地从其他线程调用pictureBox1.Invoke(new Action(() =>{pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;axWindowsMediaPlayer1.Visible = false;pictureBox1.Visible = true;pictureBox1.Image = img;Delay(Convert.ToInt32(Time));}));}else{// 如果已经在创建控件的线程上，直接设置值pictureBox1.Visible = true;axWindowsMediaPlayer1.Visible = false;pictureBox1.Image = img;Thread.Sleep(Convert.ToInt32(Time));}
}private void ChangeBringToFrontVideo(string filePath)
{if (axWindowsMediaPlayer1.InvokeRequired){// 使用Invoke安全地从其他线程调用axWindowsMediaPlayer1.Invoke(new Action(() =>{axWindowsMediaPlayer1.Visible = true;pictureBox1.Visible = false;#region 解决报错的方式你可以先不加这个你试试会不会报错((System.ComponentModel.ISupportInitialize)(this.axWindowsMediaPlayer1)).BeginInit();//axWindowsMediaPlayer2为第三方控件名axWindowsMediaPlayer1.uiMode = "None"; //隐藏视频播放器布局状态栏this.Controls.Add(axWindowsMediaPlayer1);((System.ComponentModel.ISupportInitialize)(this.axWindowsMediaPlayer1)).EndInit();#endregionthis.axWindowsMediaPlayer1.URL = filePath;//1 的时候是关闭，结束了try{while (!((int)axWindowsMediaPlayer1.playState == 1)){Delay(500);}}catch{}}));}else{axWindowsMediaPlayer1.Visible = true;pictureBox1.Visible = false;#region 解决报错的方式你可以先不加这个你试试会不会报错((System.ComponentModel.ISupportInitialize)(this.axWindowsMediaPlayer1)).BeginInit();//axWindowsMediaPlayer2为第三方控件名axWindowsMediaPlayer1.uiMode = "None"; //隐藏视频播放器布局状态栏this.Controls.Add(axWindowsMediaPlayer1);((System.ComponentModel.ISupportInitialize)(this.axWindowsMediaPlayer1)).EndInit();#endregionthis.axWindowsMediaPlayer1.URL = filePath;//1 的时候是关闭，结束了while (!((int)axWindowsMediaPlayer1.playState == 1)){Delay(500);}}
}

六：隐藏标题栏后需要可拖拽缩放

可通过游标去实现我这边就不粘出来了
