Check if toolbox tool exists before opening it

Question

Is there a way to check if a toolbox tool exists before opening it using the arcgis pro sdk? When I tried OpenToolDialog()  on a tool not in the toolbox it tried to open it and failed.

string analysisToolName = "C:\Program Files\ArcGIS\Pro\Resources\ArcToolBox\Toolboxes\Analysis Tools.tbx\NewToolBuffer";

var param_values = Geoprocessing.MakeValueArray();
 param_values = null;
 if (File.Exists(analysisToolName))
 {
    Debug.WriteLine("FOUND");
    Geoprocessing.OpenToolDialog(analysisToolName, param_values);
 }
 else
 {
    Debug.WriteLine("DID NOT FIND TOOL");
 }

I tried this but when I run OpenToolDialog it is not throwing an exception so it just finishes and I see this. Is there a way to throw an exception when Tool has failed to open happens?

Map Vis You can use a try/catch statement. The exception can also be used to handle other specific error other than the tool not being loaded. var param_values = Geoprocessing.MakeValueArray(); param_values = null; try { Geoprocessing.OpenToolDialog(analysisToolName, param_values); } catch (Exception e) { Debug.WriteLine("DID NOT FIND TOOL"); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
