我要评论ao的版本为10.2，开发的语言是c#。栅格数据来源irasterdataset接口。
irasterbandcollection prasterbandcollection = prasterdataset as irasterbandcollection;
irasterband prasterband = prasterbandcollection.item(0);
iraster praster = (prasterdataset as irasterdataset2).createfullraster();
irawpixels prawpixels = prasterband as irawpixels;
irasterprops prasterprops = prasterband as irasterprops;
int dheight = prasterprops.height;
int dwidth = prasterprops.width;
ipnt pntsize = new pntclass();
pntsize.setcoords(dheight, dwidth);
ipnt ppixelblockorigin = new pntclass();
ppixelblockorigin.setcoords(0, 0);
ipixelblock pixelblock = praster.createpixelblock(pntsize);
prawpixels.read(ppixelblockorigin, pixelblock);
system.array arr = (system.array)(pixelblock as ipixelblock3).get_pixeldata(0);
for (int i = 0; i < dheight;i++ )
{
for (int j = 0; j < dwidth; j++)
{
float number = 0;
float.tryparse(arr.getvalue(i,j).tostring(),out number);
}
}
