使用Microsoft.DirectX.AudioVideoPlayback播放視頻時出錯; 程序集版本錯誤

Question

我試圖在基於c＃windows form的應用程序上嵌入視頻，使用程序集Microsoft.DirectX.AudioVideoPlayback但是得到以下錯誤

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

我正在使用Visual Studio 2010 .NET版本4.0還安裝了Microsoft DirectX SDK任何鏈接更新版本的庫或任何替代？

碼：

using Microsoft.DirectX.AudioVideoPlayback;
namespace MathBook
{
    public partial class Form1 : Form
    {
        Video vd;
        public Form1()
        { InitializeComponent(); }

        private void Form1_Load(object sender, EventArgs e)
        { }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                vd = new Video(@"absolute_file_location.wmv", true);
                vd.Owner = panel1;
                vd.Play();
            }
            catch (Exception ex) { }
        }
    }
}

Answer 1

如錯誤消息所示，您需要其他配置信息。

在您的應用配置文件中將useLegacyV2RuntimeActivationPolicy設置為true

<startup useLegacyV2RuntimeActivationPolicy="true">
   <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
