Write statisticsField in Dissolve

DavidMrázek

Hello,

how to write statisticsFields in managment Dissolve correctly?

I tried it like this:

 object[] sumArea = { "Shape_Area", "SUM" };
            object[] sumLenght = { "Shape_Length", "SUM" };
            object[] statisticsFields = { sumArea, sumLenght };
  object[] listOfPara = { shpLayer, file, dissolveFields, statisticsFields, "MULTI_PART", "DISSOLVE_LINES" };
//second
 object[] statisticsFields = { "Shape_Area", "SUM" ,"Shape_Length", "SUM"}
 object[] listOfPara = { shpLayer, file, dissolveFields, statisticsFields, "MULTI_PART", "DISSOLVE_LINES" };

Both without success.

 

I will be happy for any advice.

Thank you in advance

David

Hi,

Have you tried like this:

string statisticsFields = "Shape_Length SUM;Shape_Area SUM";
var parameters = Geoprocessing.MakeValueArray(shpLayer, file, dissolveFields, statisticsFields, "MULTI_PART", "DISSOLVE_LINES");
var gpResult = Geoprocessing.ExecuteToolAsync("Dissolve_management", parameters, null, CancelableProgressor.None, GPExecuteToolFlags.None);
