c# gdal 错误 "System.ApplicationException："D：\test.tiff， band 1： GDALRasterIOExtraArg 的未处理版本"

Question

使用GDAL Band.WriteRaster(int，int，int、short[](，int，整型，整型，osgeo。GDAL。Rasterioextrarg(函数对原始图像重新采样，但运行时出现错误：；系统应用程序异常："D： \test.tiff，band 1：未处理的gdalasterioextraarg版本">

public Dataset NearestNeighbour(Dataset oriimg,Dataset srcimg)
{
OSGeo.GDAL.RasterIOExtraArg extraArg=new RasterIOExtraArg();
extraArg.eResampleAlg =RIOResampleAlg.GRIORA_NearestNeighbour;
//DataType dataType = oriimg.GetRasterBand(1).DataType;
int bandsnum = oriimg.RasterCount;
int orilines = oriimg.RasterYSize;
int orisamples = oriimg.RasterXSize;
int srclines = srcimg.RasterYSize;
int srcsamples = srcimg.RasterXSize;
int[] oribanddata = new int[orilines * orisamples];
for(int i=1;i<=bandsnum;i++)
{
oriimg.GetRasterBand(i).ReadRaster(0, 0, orisamples, orilines, oribanddata, orisamples, orilines, 0, 0);
srcimg.GetRasterBand(i).WriteRaster(0, 0, orisamples, orilines, oribanddata, srcsamples, srclines, 0, 0, extraArg);
}
return srcimg;
}

Answer 1

您需要设置

extraArg.nVersion = 1;
