Add results (C#)

Hello all. I'm very new to C#. I've been putting together bits of code to create a tool that gets the current selection (of pipe) and displays the "Length" parameter for each instance. The attached jpg shows the current result.

 

What I'd like to do next is provide a TOTAL length for all the pipes selected.

 

How can I append/add to my "p" value (below) for each instance?

(Sorry about the formatting of the code)

 

#region Namespaces

using System;

using System.Collections.Generic;

using Autodesk.Revit.ApplicationServices;

using Autodesk.Revit.Attributes;

using Autodesk.Revit.DB;

using Autodesk.Revit.UI;

using Autodesk.Revit.UI.Selection;

using System.Windows.Forms;

using System.Diagnostics;

using Autodesk.Revit.DB.Plumbing;

using System.Text;

#endregion

namespace TryThis

{

[Transaction(TransactionMode.Manual)]

public class Class1 : IExternalCommand

{

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)

{

try

 

// Select some elements in Revit before invoking this command

// Get the handle of current document.

UIDocument uidoc = commandData.Application.ActiveUIDocument;

 

// Get the element selection of current document.

Selection selection = uidoc.Selection;

 

ElementSet collection = selection.Elements;

if (0 == collection.Size)

 

// If no elements selected.

TaskDialog.Show("Revit", "You haven't selected any elements.");

}

else

{

String info = "Pipe Lengths are: ";

foreach (Pipe pipe in collection)

 

//this is the code I would like to add to for each instance of pipe, so I can pull a TOTAL later

Parameter p = pipe.get_Parameter(BuiltInParameter.CURVE_ELEM_LENGTH);

info += "\n\t" + p.AsValueString();

}

TaskDialog.Show("Revit", info);

}

}

catch (Exception e)

{

message = e.Message;

return Autodesk.Revit.UI.Result.Failed;

}

return Result.Succeeded;

}

}

}

**UPDATE**

 

I figured out how to add the results and total it. This is the code I added:

 

double total = 0; (located in my else statement)

total = total += p.AsDouble(); (located in my foreach statment)

 

//Finally. Show results:

TaskDialog.Show("Total", total.ToString());

 

My variable "p" (which is "pipe.get_Parameter(BuiltInParameter.CURVE_ELEM_LENGTH)", if converted straight to a string, gives me a length in this format: 12'-6".

 

But, when I use the code above to add/total the pipe lengths it converts the 12'-6" to 12.5. Is there a way to convert this back to displaying feet and inches?

 

Thank you ahead of time.

Hi, RG-ClearyZ

Recently I wrote simple class for unit converting. Jeremy Tammik wrote a post on his blog about unit converter and my class . You can read it here

 

Good luck, Victor
