How to export a raster dataset to a geodatabase and specify options

static void exportToGeodatabase()throws Exception{
    //    Use CopyRaster GP tool to load single raster dataset to GDB with options.
    //    Syntax: CopyRaster <in_raster> <out_rasterdataset> {config_keyword} {background_value} {nodata_value} {NONE | OneBitTo8Bit} {NONE | ColormapToRGB}

    //    Set parameters in the same order as the syntax shows, change any parameter to fit your data and loading requirement.
    IVariantArray parameters = new VarArray();
