最近由于工作需要，需要做一个播放软件，在网上参考了很多例子，园子里有很多代码。其中最多的就是wpf自带的MediaElement控件，或者VLC视频播放器。

先附我自己查询资料的链接：

MediaEmelent控件例子

VLC

由于我电脑可能是Ghost系统或者由于被优化了。我发现我的MediaElement无法播放任何视频。通过控制面板关闭媒体中心之后，再也打不开了。真是坑！！！

只能放弃自带控件，查到有一个VLC的NET版。so。。。

附vlc.dotnet的github链接

首先，自己在nuget里面下载所需要的扩展：

完成之后就看示例代码咯，github里面是有example的

 1 <Window x:Class="Vlc.DotNet.Wpf.Samples.MainWindow"
 2         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
 5         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
 6         xmlns:local="clr-namespace:Vlc.DotNet.Wpf.Samples"
 7         xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"
 8         mc:Ignorable="d"
 9         Title="MainWindow" Height="350" Width="525">
10     <Grid>
11         <Grid.RowDefinitions>
12             <RowDefinition Height="*"/>
13             <RowDefinition Height="Auto"/>
14             <RowDefinition Height="Auto"/>
15             <RowDefinition Height="Auto"/>
16             <RowDefinition Height="Auto"/>
17             <RowDefinition Height="Auto"/>
18         </Grid.RowDefinitions>
19 
20         <wpf:VlcControl Grid.Row="0" x:Name="myControl"/>
21 
22         <Button Grid.Row="1" Click="OnPlayButtonClick">Play</Button>
23         <Button Grid.Row="2" Click="OnForwardButtonClick" x:Name="Forward">Forward</Button>
24         <Button Grid.Row="3" Click="GetLength_Click" x:Name="GetLength">Get Length</Button>
25         <Button Grid.Row="4" Click="GetCurrentTime_Click" x:Name="GetCurrentTime">Get Current Time</Button>
26         <Button Grid.Row="5" Click="SetCurrentTime_Click" x:Name="SetCurrentTime">Set Current Time to 5s</Button>
27     </Grid>
28 </Window>

首先加上 xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"

然后加上 <wpf:VlcControl Grid.Row="0" x:Name="myControl"/>

55             SetCurrentTime.Content = myControl.MediaPlayer.Time + " ms";
56         }
57     }
58 }
