我收到此運行時錯誤： InvalidProgramException: Invalid IL code . 我正在使用unity 5.3.1f1 . 該項目是編輯器擴展 . 代碼的簡化版本是：

public unsafe class PPAGraph

{

PaddedImage downSampleImage;

int downSampleRate;

internal void Calculate(PaddedImage sourceImage)

{

sourceImage.DownSample(downSampleImage, downSampleRate);

}

此行發生此錯誤 .

InvalidProgramException：Assets.UPlus.TerrEngine.PaddedImage中的IL代碼無效：DownSample(Assets.UPlus.TerrEngine.PaddedImage，int)：IL_00a9：stloc.s 15 Assets.UPlus.TerrEngine.PPAGraph.Calculate(Assets.UPlus.TerrEngine .

DownSample方法是：

public void DownSample(PaddedImage downSampImg, int downsampleRate)

{

int dsW = downSampImg.Width;

int dsH = downSampImg.Height;

float* dsPix = downSampImg.Pixels,padDSPix=downSampImg.PaddedPixels;

int pad = Padding;

int twoPad = pad + pad;

float* rowMyPix = PaddedPixels;

rowMyPix += pad*PaddedWidth + pad;

float* myPix;

int yStep = downsampleRate * PaddedWidth;

int dsPad = downSampImg.Padding;

int twoDSPad = dsPad + dsPad;

padDSPix += downSampImg.PaddedWidth*dsPad + dsPad;

if (downSampImg.PixelsPtr != IntPtr.Zero)

{

for (int y = 0; y < dsH; y++)

{

myPix = rowMyPix;

for (int x = 0; x < dsW; x++)

{

*padDSPix++ = *dsPix++ = *myPix;

myPix += downsampleRate;

}

padDSPix += twoDSPad;

rowMyPix += yStep;

}

}

else

{

for (int y = 0; y < dsH; y++)

{

myPix = rowMyPix;

for (int x = 0; x < dsW; x++)

{

*padDSPix++ = *dsPix++ = *myPix;

myPix += downsampleRate;

}

padDSPix += twoDSPad;

rowMyPix += yStep;

}

}

}
