Create fishnet

rs_gs — Tue, 25 Jun 2024 10:48:39 GMT

I want to create a fishnet using the csharp code，Why isn't it generated after the code runs？thank you.

await QueuedTask.Run(async () =>
{

string out_feature_class = @"F:\data\fishnet.shp";
double cellSizeWidth = 0;
double cellSizeHeight = 0;
long numRows = 10;
long numCols = 10;
string labels = "NO_LABELS";
string template = "DISPLAY";
string geometryType = "POLYGON";
var parameters = Geoprocessing.MakeValueArray(out_feature_class, null, null, cellSizeWidth, cellSizeHeight, numRows, numCols, "",labels, template, geometryType);

await Geoprocessing.ExecuteToolAsync("management.CreateFishnet", parameters）；

}
});

Does the shapefile get created on your drive but isn't added to the map? If so, set the GPExecuteToolFlags enumeration to AddOutputsToMap in the ExecuteToolAsync.

await Geoprocessing.ExecuteToolAsync("management.CreateRandomPoints", createPointsParamsValueArray, null, CancelableProgressor.None, GPExecuteToolFlags.AddOutputsToMap);

Or does it result in nothing getting created? I return an IGPResult from my geoprocessing tasks to check if they're successful.

IGPResult createRandomPointsMessage = await Geoprocessing.ExecuteToolAsync("management.CreateRandomPoints", createPointsParamsValueArray, null, CancelableProgressor.None, GPExecuteToolFlags.AddOutputsToMap); if (createRandomPointsMessage.IsFailed) { System.Diagnostics.Debug.WriteLine("Create random points errors"); }

I checked the file location，no shapefile （fishnet ）was created.

The problem is solved, two parameters are added（origin_coord，y_axis_coord）, and two parameters are modified（cell_width，cell_height）.And delete this code：LayerFactory.Instance.CreateLayer(new Uri(out_feature_class), mapView.Map)
