我试图从我的硬盘播放视频avi文件，但得到fileloadeexception错误的原因

这是我在Form1中的代码:

private void play()
        {
            pictureBox1.Load(vp.PlayVideoFile(@"D:'testdata'new.avi"));
        }

vp是VideoPlayer类的一个变量:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ScreenVideoRecorder
{
    class VideoPlayer
    {
        public VideoPlayer()
        {
        }
        public string PlayVideoFile(string fileName)
        {
            //create the video
            Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(fileName);
            //Play the video (put this in a buttons click event)
            video.Play();
            //Pause the video (put this in a buttons click event)
            video.Pause();
            //Stop the video (put this in a buttons click event)
            video.Stop();
            return fileName;
        }
    }
}

为什么我得到这个异常?

混合模式程序集是根据运行时版本'v1.1.4322'构建的，如果没有额外的配置信息，则无法在4.0运行时中加载

还需要哪些额外的配置信息?怎么做呢?

编辑:

现在我在我的VideoPlayer类中得到一个异常:

Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(fileName);

异常是:Loader lock was detected:

DLL 'C:'WINDOWS'assembly'GAC'Microsoft.DirectX'1.0.2902.0__31bf3856ad364e35'Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

LoaderLock被检测到消息:DLL 'C:'WINDOWS'assembly'GAC'Microsoft.DirectX'1.0.2902.0__31bf3856ad364e35'Microsoft.DirectX. DLL '试图在操作系统加载器锁定内托管执行。不要尝试在DllMain或图像初始化函数中运行托管代码，因为这样做会导致应用程序挂起。
