如何解决缺少 dll 的异常？ dll文件在目录中

Question

这一行：

Boolean bl = InitializeDirectX(mypb);

以及使用 DirectX 的 InitializeDirectX 方法：

public Boolean InitializeDirectX(PictureBox pb)
        {
            DispMode = Manager.Adapters[Manager.Adapters.Default.Adapter].CurrentDisplayMode;
            D3Dpp = new PresentParameters();
            D3Dpp.BackBufferFormat = DispMode.Format;
            D3Dpp.PresentFlag = PresentFlag.LockableBackBuffer;

            D3Dpp.SwapEffect = SwapEffect.Discard;
            D3Dpp.PresentationInterval = PresentInterval.One; //wait for vertical sync. Synchronizes the painting with
            //monitor refresh rate for smoooth animation
            D3Dpp.Windowed = true; //the application has borders

            try
            {
                D3Ddev = new Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, pb.Handle,
                                                                           CreateFlags.SoftwareVertexProcessing, D3Dpp);
                D3Ddev.VertexFormat = CustomVertex.PositionColored.Format;
                D3Ddev.RenderState.Lighting = false;
                D3Ddev.RenderState.CullMode = Cull.CounterClockwise;

                backTexture = TextureLoader.FromStream(D3Ddev, mymem);
                scannedCloudsTexture = new Texture(D3Ddev, 512, 512, 1, Usage.Dynamic, Format.A8R8G8B8, Pool.Default);

                //sprite is used to draw the texture
                D3Dsprite = new Sprite(D3Ddev);

                return true;
            }
            catch
            {
                return false;
            }
        }

抛出异常就行了：

Boolean bl = InitializeDirectX(mypb);

例外是 FileNotFoundException：

A first chance exception of type 'System.IO.FileNotFoundException' occurred in My Weather Station.exe

Additional information: Could not load file or assembly 'Microsoft.DirectX.Direct3DX.dll' or one of its dependencies. The specified module could not be found.

并且文件 Microsoft.DirectX.Direct3DX.dll 确实存在于我在参考文件中看到的目录中。我也没有在这个 dll 的引用中看到任何黄色或文件丢失的状态。

而且我之前没有出现异常，就像 dll 文件中的某些内容发生了变化一样？

System.IO.FileNotFoundException occurred
  _HResult=-2147024770
  _message=Could not load file or assembly 'Microsoft.DirectX.Direct3DX.dll' or one of its dependencies. The specified module could not be found.
  HResult=-2147024770
  IsTransient=false
  Message=Could not load file or assembly 'Microsoft.DirectX.Direct3DX.dll' or one of its dependencies. The specified module could not be found.
  Source=My Weather Station
  FileName=Microsoft.DirectX.Direct3DX.dll
  FusionLog=""
  StackTrace:
       at mws.ScanningClouds.InitializeDirectX(PictureBox pb)
       at mws.ScanningClouds.ScanClouds_Load(Object sender, EventArgs e) in d:\C-Sharp\myprog.cs:line 179
  InnerException:

第 179 行是：

Boolean bl = InitializeDirectX(mypb);

如果 dll 中的某些依赖项丢失了，不知道为什么，我怎样才能找到哪些依赖项？

日期：

这是文件DirectXDirect3DX.dll的dotPeek中的引用

在我的项目中：

我不明白 T.S 解决方案中的记事本部分。

更新

这是我的项目文件中的引用：

您的计算机上可能未安装Directx 的组件或部分。在你的机器上安装DirectX 可以解决这个问题。
