On possible problem in this particular example is that the ArcInfo ASCII Grid (AAIGrid) driver does not support the Create method of the GDAL API, only the CreateCopy method, correct? (Please correct me if I am wrong about this.) Therefore the procedure for converting IMG to ArcInfo ASCII Grid with code will be slightly different than the one you outlined. C++, C, and Python examples are here: http://www.gdal.org/gdal_tutorial.html#gdal_tutorial_createcopy

The idea is that you: 1) open your source dataset (the img file) 2) instantiate the arcinfo ascii driver (gdal.GetDriverByName in python to get a driver instance) 3) use the driver instance to create a new file with the correct parameters (size, #bands, datatype) 4) copy the metadata (projection, geotransform) from the input to the output file 5) read data from the input file 6) write data to the output file Depending on the size of the file and the amount of memory, you might need to read/write in a loop per chunk or line instead of reading the whole shebang at once and writing after that. About the details (in C#) I can't help you, you'll have to digg a bit yourself. Maybe there are some C# examples included in the gdal source code? Good luck! Vincent.
