開發環境：

Visual Studio 2015

.Net Framework 4.5

1.新建一個Windows窗體應用程序

修改框架為.Net Framework 4.5

2.管理NuGet包

下載安裝5個包

VideoLAN.LibVLC.Windows

Vlc.DotNet.Core

Vlc.DotNet.Core.Interops

Vlc.DotNet.Forms

Vlc.DotNet.Wpf

3.添加VlcControl

工具箱添加VlcControl，dll位於當前項目中

將VlcControl添加到窗體上

在VlcControl的VlcLibDirectoryNeeded事件中添加如下代碼（必須）

　　　　　/// <summary>
        /// Looks for the vlc directory on the opening of the app
        /// Opens a dialog if the libvlc folder is not found for the user to pick the good one
        /// Folder for 32bits should be "libvlc\win-x86\" and "libvlc\win-x64\" for 64 bits
        /// </summary>
        ///
 
 <param name="sender"></param>
        /// <param name="e"></param>
        private void myVlcControl_VlcLibDirectoryNeeded(object sender, VlcLibDirectoryNeededEventArgs e)
        {
            var currentAssembly = Assembly.GetEntryAssembly();
            var currentDirectory = new
 
 FileInfo(currentAssembly.Location).DirectoryName;

            if (currentDirectory == null)
                return;
            if (IntPtr.Size == 4)
                e.VlcLibDirectory = new DirectoryInfo(Path.GetFullPath(@".\libvlc\win-x86\"));
            else
                e.VlcLibDirectory = new DirectoryInfo(Path.GetFullPath(@".\libvlc\win-x64\"));

            if (!e.VlcLibDirectory.Exists)
            {
                var folderBrowserDialog = new System.Windows.Forms.FolderBrowserDialog();
                folderBrowserDialog.Description = "Select Vlc libraries folder.";
                folderBrowserDialog.RootFolder = Environment.SpecialFolder.Desktop;
                folderBrowserDialog.ShowNewFolderButton = true;
                if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
                {
                    e.VlcLibDirectory = new DirectoryInfo(folderBrowserDialog.SelectedPath);
                }
            }
        }

4.播放在線視頻

使用VlcControl.Play()方法播放一個網絡視頻（本地視頻不能播放原因未知）

vlcControl1.Play("http://**************/******.flv");
