Executing Intersect tool in arcgis pro .net sdk

[omorfaruk]

In ArcGIS Pro version 2.0.0 I use this code to execute merge tool  

public async Task<bool> ExecuteToolAsync()
{
var valueArray = await QueuedTask.Run(() =>
{
// Creates a 8000-meter buffer around the geometry object
// null indicates a default output name is used
return Geoprocessing.MakeValueArray(_inputs, _output);
});
var result = await Geoprocessing.ExecuteToolAsync("Merge_management", valueArray);
return !result.IsFailed;
}

where _inputs is list of fullpath of layers 

it works well.

but to execute intersect tool i use this:

public async Task<bool> ExecuteToolAsync()
{
var _inpputs= new List<string>() { _featureLayer1, _featureLayer2 };
var valueArray = await QueuedTask.Run(() => Geoprocessing.MakeValueArray(_inpputs, _outputFeatureClass, "ALL, "0", "POINT"));

var result = await Geoprocessing.ExecuteToolAsync("Intersect_analysis", valueArray);
return !result.IsFailed;
}

It doesn't  work. How can I solve this.

Insert this line before your return statement:

Geoprocessing.ShowMessageBox(result.Messages, "Intersect Messages", 
                             result.IsFailed ? GPMessageBoxStyle.Error : GPMessageBoxStyle.Default);

Let me know what returned messages do you see. You'll find some snippets in this link:

Could you please put a break at this line and check what values do you get for valueArray variable when you step-over?

var valueArray = await QueuedTask.Run(() => Geoprocessing.MakeValueArray(_inpputs, _outputFeatureClass, "ALL, "0", "POINT"));

Where (how) are you getting the values of _featureLayer1 and _featureLayer2 - where are these variables defined? How are they defined.

var _inpputs= new List<string>() { _featureLayer1, _featureLayer2 };

Are these Map layer objects obtained from a 'map' object - such as map.GetLayersAsFlattenedList() ... ? If so, you can call GetFeatureClass on both _featureLayer1 and _featureLayer2 as follows:

_featureLayer1.GetFeatureClass()  and _featureLayer2.GetFeatureClass() and use these feature classes instead.

@NobbirAhmed , Thanks for your response. It helped me resolve my problem. The only thing I changed was the following:

var _inpputs = new List<FeatureLayer>() {_featureLayer1,_featureLayer2};

A list of feature layer or feature class will work for this geoprocessing tool. 

Thanks!
