Where can I find info on name and parameters for Geoprocessing tools

[René_AstadDupont]

I try to execute a geoprocessing tool "SplitLineBypoint" and I have the code below, witch do not give me the expected result.

My first question is:

      Where can i find the name/id of the tool. My guess in the code are "analysis.SplitLineAtPoint", but that just my guess.

secondly: Were can I find documentation on the values that I have to pack into the valueArray.

private async Task<bool> SplitPipesByJunctions()
        {
            var valueArray = await QueuedTask.Run(() =>
            {
                mVannledninger = GetLayer("Vannledninger");
                mJunctions = GetLayer("Vann_nett_Junctions");
                mDestVannledninger = GetLayer("Vannledninger_SplitLineAtPoi");

                return Geoprocessing.MakeValueArray(mVannledninger, mJunctions, mDestVannledninger, 0.1 );
            });

            var res = await Geoprocessing.ExecuteToolAsync("analysis.SplitLineAtPoint", valueArray);

            return true;
        }

SplitLineAtPoint ... is a geoprocessing tool in both arcmap and PRO.

Documentation of any ArcToolbox tools can be found in the appropriate help topic regardless of the developing language

Hei Dan

Thank you for the resonse.

I have been looking at that page, but that did not really give me the nessesary information. 

It might be my mistake, but i dont find the name to use in C# at that page, and i don't find any C#  examle.

And whitch parameters should I use? Name of the featureclass? The Fetureclass? a geometry? Where can I find information on that?

The following has C# example code: ArcGIS Pro 2.1 API Reference Guide - ExecuteToolAsync  .  Use the references from Dan to understand what the tool's arguments are to pass using ExecuteToolAsync.

Thank you Joshua.

Your answer was very helpfull, even it did not directly answer my question.

To answer my own question.

Right clikking the tool of interest in ArcGIS Pro and selecting properties.

eg. "Split Line at Point" show:

In this example the name to use is: "toolboxsalias.SplitLineAtPoint".  I still don't know where to find toolboxalias" but i think that this can be figured out by a qualified guess.

The Parameters Show a table of parameters and their Data Type to pack into the valueArray. 

Hope this can help someone else.
