Error running geoprocessing tool "management.createfeatureclass"

zhangjinzhou — Fri, 24 Jan 2025 17:18:59 GMT

I am trying to create an empty feature class in a file geodatabase, but it's not working. The geoprocessing tool doesn't provide a specific error message. When I run the tool on a folder, it creates an empty shapefile without any issues. Here is my code:

string path = analysis.Path + "\\CVAnalysis.gdb"; // This doesn't work. The CVAnalysis.gdb exists, and I have no problem creating a feature class when running the geoprocessing tool manually in ArcGIS Pro. string path = analysis.Path; // This works and output a shapefile. var parameters = Geoprocessing.MakeValueArray( path, "NewLayer", "Polygon" ); string toolName = "management.CreateFeatureclass"; var result = await Geoprocessing.ExecuteToolAsync(toolName, parameters, null, null, null); if (result.IsFailed) { foreach (var message in result.Messages) { MessageBox.Show(message.Text); // There is no message in the error } } else { System.Diagnostics.Debug.WriteLine("Feature class created successfully."); }

Hi,

Your code works fine. There are some reasons why you can't create featureclass within geodatabase:

1. analysis.Path ends with "\". I would recommend to use Path.Combine method to construct full path.

2. Your geodatabase already contains "NewLayer" featureclass.

I would recommend to use ExecuteToolAsync method with GPToolExecuteEventHandler parameter as in API reference sample. It will show issues with input parameters.

System.Threading.CancellationTokenSource _cts; string ozone_points = @"C:\data\ca_ozone.gdb\O3_Sep06_3pm"; string[] args = { ozone_points, "OZONE", "", "in_memory\\raster", "300", "EMPIRICAL", "300", "5", "5000", "NBRTYPE=StandardCircular RADIUS=310833.272442914 ANGLE=0 NBR_MAX=10 SECTOR_TYPE=ONE_SECTOR", "PREDICTION", "0.5", "EXCEED", "", "K_BESSEL" }; string tool_path = "ga.EmpiricalBayesianKriging"; _cts = new System.Threading.CancellationTokenSource(); var result = await Geoprocessing.ExecuteToolAsync(tool_path, args, null, _cts.Token, (event_name, o) => // implement delegate and handle events { switch (event_name) { case "OnValidate": // stop execute if any warnings if ((o as IGPMessage[]).Any(it => it.Type == GPMessageType.Warning)) _cts.Cancel(); break; case "OnProgressMessage": string msg = string.Format("{0}: {1}", new object[] { event_name, (string)o }); System.Windows.MessageBox.Show(msg); _cts.Cancel(); break; case "OnProgressPos": string msg2 = string.Format("{0}: {1} %", new object[] { event_name, (int)o }); System.Windows.MessageBox.Show(msg2); _cts.Cancel(); break; } }); var ret = result; _cts = null;

The problem was invalid featureclass name with number at the beginning and space. With the code sample shared by @GKmieliauskas, I was able to se the error message. Thank you @GKmieliauskas !
