ArcGIS Pro Add-in: How to use Geoprocessing tools

JadedEarth

Hi,

I'm creating an Add-in Application for ArcGIS Pro v2.9 using Visual Studio 2019 in C#. 

How do I access the geoprocessing assemblies so I can execute them in my codes?  I have the following code but I'm getting an error:  "Unable to load DLL ArcGISVersion.dll.  The specified module could not be found."

Here's my code snippet:

 

using ESRI.ArcGIS.Geoprocessor;
using ESRI.ArcGIS.DataManagementTools;

private void ConnectToSQLServerDb()
{
            //Declares variables here...

            //Initialize a geoprocessing object
            Geoprocessor GP = new Geoprocessor();
            CreateDatabaseConnection dbCon = new CreateDatabaseConnection();

            try
            {
                //Specify parameters
                dbCon.out_folder_path = outFolder;
                dbCon.out_name = outName;
                dbCon.database_platform = dbPlatform;
                dbCon.instance = sqlInstance;
                dbCon.database = dbName;
                dbCon.account_authentication = "OPERATING_SYSTEM_AUTH";
     
                //Execute tool
                GP.OverwriteOutput = true;
                GP.Execute(dbCon, null);
            }
            catch (Exception ex)
            {
                ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Failed to reset table: " + ex.Message, "Error Message", MessageBoxButton.OK, MessageBoxImage.Error);
            }
            finally
            {
                GP = null;
                dbCon = null;
            }
}

This looks like code from ArcObjects to run Geoprocessing tools. It's much different in ArcGIS Pro, using different assemblies and supplying the parameters using a list of arguments rather than properties. Take a look at the documentation on how to run Geoprocessing tools.

Here's an example I use that runs the "Create Feature Class" tool.

using ArcGIS.Desktop.Core.Geoprocessing;
using ArcGIS.Core.Geometry;
using System.Collections.Generic;
using System.Threading.Tasks; 

   public static async Task<IGPResult> CreateLayer(string path, string featureclassName, string featureclassType, int SR_wkid)
    {
      List<object> arguments = new List<object>
      {
        // store the results in the default geodatabase
        //CoreModule.CurrentProject.DefaultGeodatabasePath,
        path,
        // name of the feature class
        featureclassName,
        // type of geometry
        featureclassType,
        // no template
        "",
        // no m values
        "DISABLED",
        // no z values
        "DISABLED"
      };
      await QueuedTask.Run(() =>
      {
        // spatial reference
        arguments.Add(SpatialReferenceBuilder.CreateSpatialReference(SR_wkid));
      });

      IGPResult result = await Geoprocessing.ExecuteToolAsync("CreateFeatureclass_management", Geoprocessing.MakeValueArray(arguments.ToArray()), null, null, null, GPExecuteToolFlags.None);
      return result;
    }
