C# 我正试图从我的硬盘播放视频avi文件，但收到FileLoadException错误为什么？

这是我在表格1中的代码：

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

vp是我的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;
        }
    }
}

为什么我会得到这个例外

混合模式程序集是根据运行时版本“v1.1.4322”生成的，如果没有其他配置信息，则无法在4.0运行时中加载

它需要什么额外的配置信息？怎么做呢

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：

现在我在视频播放器课上遇到了一个例外：

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

异常情况是：检测到加载程序锁定：

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\uu 31bf3856ad364e35\Microsoft.DirectX.DLL”正在尝试在OS加载程序锁内执行托管。请勿尝试在DllMain或image initialization函数中运行托管代码，因为这样做可能会导致应用程序挂起。

使用以下内容将app.config文件添加到项目中：

 <?xml version="1.0"?>
 <configuration>
   <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v1.0"/>
    <supportedRuntime version="v4.0"/>
  </startup>
 </configuration>

您是否尝试添加VC++运行时DLL，并且.Net不向后兼容您需要安装正确的.Net版本：（尝试Laszlokiss88我现在试过当我运行程序时我看到弹出窗口说我需要安装.NET 1.0当我单击“确定”时它将我的浏览器带到搜索引擎网页：我将此添加到app.config：但现在我在另一个地方遇到异常我用新的异常编辑我的问题。我已经下载了d it。我试图在2010年6月安装directx，但在安装结束时，它说安装失败。dll不在那里，所以我下载了它。我使用windows 8 64位和vidusal studio 2012 pro，我的项目在.net 4.0上。你能复制url吗？可能有一个4.0版本。你安装了directx软件DevKit吗？（也许您应该从此引用dll。）
