Delete Field

Hi,

I'm trying to get the columns out, but it doesn't do anything at all, I tried it gradually, I tried them all at once but without any success. Can anyone advise me?

FeatureLayer flRamyPresahu = mapView.Map.FindLayers(ramyPresahu).FirstOrDefault() as FeatureLayer; FeatureClass fcRamyPresahu = flRamyPresahu.GetTable() as FeatureClass; var minX = "ExtentMinX"; var minY = "ExtentMinY"; var maxX = "ExtentMaxX"; var maxY = "ExtentMaxY"; object[] sloupce = {maxX,maxY,minX,minY}; object[] seznamSloupcu = { fcRamyPresahu, sloupce }; await StartATask("management.DeleteField", seznamSloupcu);

If your FeatureClass is in a geodatabase (file, mobile, enterprise, or memory), you can use this snippet to remove a field

https://github.com/Esri/arcgis-pro-sdk/wiki/ProSnippets-Geodatabase#removing-fields-from-a-table

Otherwise, you can use this code to use the GeoProcessing tool to remove a field.

var args = Geoprocessing.MakeValueArray(fcRamyPresahu, sloupce); IGPResult result = await Geoprocessing.ExecuteToolAsync("management.DeleteField", args, null, null, null, GPExecuteToolFlags.None); //the last parameter does not add the result to the map

Read this page on more information about using GeoProcessing tools

What does your StartATask function look like?

public static async Task<bool> StartATask(string funcArc, object[] parame) { var parameters = Geoprocessing.MakeValueArray(parame); await Geoprocessing.ExecuteToolAsync(funcArc, parameters); return true; }

Instead of just returning true, why not get a report on why it failed?

public static async Task<bool> StartATask(string funcArc, object[] parame) { var parameters = Geoprocessing.MakeValueArray(parame); var result = await Geoprocessing.ExecuteToolAsync(funcArc, parameters); if (result.IsFailed) { Geoprocessing.ShowMessageBox(result.Messages, "Content Header", GPMessageBoxStyle.Error); } return !result.IsFailed; }
