WPF視頻音頻實現(xiàn)方法解析
作者:佚名
WPF視頻音頻在實際代碼編寫中是比較常見的。我們會通過兩段代碼示例來為大家詳細介紹有關(guān)實現(xiàn)方法,幫助大家理解。
WPF視頻音頻的播放方法可以通過一段代碼來幫助我們實現(xiàn)。這里將會為大家?guī)碓敿毜膶崿F(xiàn)方法,希望對又需要的朋友有所幫助。#t#
WPF視頻音頻之Window1.xaml代碼
- < Window x:Class="WpfApplica
tion1.Window1" - xmlns="http://schemas.
microsoft.com/winfx/2006
/xaml/presentation" - xmlns:x="http://schemas.
microsoft.com/winfx/2006/xaml" - Title="Window1" Height="300"
Width="300"> - < Grid>
- < Button Height="23" Margin=
"12,12,0,0" Name="button1"
VerticalAlignment="Top" Click=
"button1_Click" Horizontal
Alignment="Left" Width="74">
Button< /Button> - < Button Height="23" Horizontal
Alignment="Right" Margin="0,12,54,0"
Name="button2" VerticalAlignment="Top"
Width="75" Click="button2_Click">
Button< /Button> - < MediaElement Name="McMediaElement"
LoadedBehavior="Manual"/> - < /Grid>
- < /Window>
WPF視頻音頻之Window1.xaml.cs代碼
- using System;
- using System.Collections.
Generic;- using System.Linq;
- using System.Text;
- using System.Windows;
- using System.Windows.Controls;
- using System.Windows.Data;
- using System.Windows.Documents;
- using System.Windows.Input;
- using System.Windows.Media;
- using System.Windows.Media.Imaging;
- using System.Windows.Navigation;
- using System.Windows.Shapes;
- namespace WpfApplication1
- {
- /// < summary>
- /// Window1.xaml 的交互邏輯
- /// < /summary>
- public partial class Window1
: Window- {
- public Window1()
- {
- InitializeComponent();
- }
- private void button1_Click(object
sender, RoutedEventArgs e)- {
- //用MediaPlayer類進行播放
- MediaPlayer player = new MediaPlayer();
- player.Open(new Uri(Environment.
CurrentDirectory + "\\music.mp3",
UriKind.Relative));- VideoDrawing aVideoDrawing =
new VideoDrawing();- aVideoDrawing.Rect = new
Rect(0, 0, 100, 100);- aVideoDrawing.Player = player;
- player.Play();
- }
- private void button2_Click(object
sender, RoutedEventArgs e)- {
- //用MediaElement控件進行播放
- McMediaElement.Source = new
Uri(Environment.CurrentDirectory
+ "\\music.mp3");- McMediaElement.Play();
- }
- }
- }
其中Environment.CurrentDirectory表示和項目生成的exe同一目錄,請將WPF視頻音頻文件copy至此目錄
