I have a code like this:...................
IGeoDataset pGeoDataset = pDataset as IGeoDataset;
IMapAlgebraOp rsalgebra = new RasterMapAlgebraOpClass();
IRasterAnalysisEnvironment rasAnaEnv = (IRasterAnalysisEnvironment)rsalgebra;
...................
rsalgebra.BindRaster(pGeoDataset, "R");
//FocalStatistics(,NbrRectangle(7,7,"CELL"),"MINORITY","NODATA")
String mpastr = "FocalStatistics(," + "NbrRectangle(7,7," + "\"" + "CELL" + "\"" + ")," + "\"" + "MINORITY" + "\"" + "," + "\"" + "NODATA" + "\"" + ")";
IGeoDataset outGetDataset=rsalgebra.Execute(mpastr);
I use ArcEngine 10.1 SDK and want achieve the FocalStatistics function same as in ArcGIS Desktop. I run this code and get messages"ERROR 010328: Syntax error at or near symbol ,.ERROR 010267: Syntax error in parsing grid expression.But when I use the text got when run the code by tracks 'String var mpastr' in the code,I got " FocalStatistics(,NbrRectangle(7,7,"CELL"),"MINORITY","NODATA") " ,and get write result in ArcGIS Desktop.I want to know how can I write the expression as mpastr to excute FocalStatistics Functions?Thanks!
