这是我在 Form1 中的代码：
private void play()
{
pictureBox1.Load(vp.PlayVideoFile(@"D:\testdata\new.avi"));
}
vp 是我的 VideoPlayer 类的变量：
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？
混合模式程序集是针对运行时的“v1.1.4322”版本构建的，如果没有额外的配置信息，则无法在 4.0 运行时中加载
它需要哪些额外的配置信息？怎么做？
System.IO.FileLoadException was unhandled
HResult=-2146232799
Message=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.

编辑：
现在我在我的 VideoPlayer 类中遇到异常：
Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(fileName);
例外情况是：检测到加载程序锁：
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.
检测到 LoaderLock 消息：DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.dll' 正在尝试在 OS Loader 锁内进行托管执行。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。
