用MediaPlayer播放MP3没声音

Question

自己写了一段很短的测试代码，但是播放没声音，代码如下

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 AudioPlayTest
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            MediaPlayer player = new MediaPlayer();

            player.Open(new Uri("D:\\KuGou\\张信哲 - 爱你没错.mp3", UriKind.RelativeOrAbsolute));
            player.Volume = 1;

            player.Play();
        }
    }
}

是我用法有问题？求解

应该不是new一下对象，还有一些属性要设置

你好 wpf萌新：

问题在于你的MediaPlayer是局部变量，你需要将其定义为字段或属性。

    public partial class MainWindow : Window
    {
        MediaPlayer player = new MediaPlayer();
        public MainWindow()
        {
            InitializeComponent();

            player.Open(new Uri("D:\\KuGou\\张信哲 - 爱你没错.mp3", UriKind.RelativeOrAbsolute));
            player.Volume = 1;

            player.Play();
        }
    }
