How to use RevitLinkType LoadFrom?

[BIM.Frankliang]

Dear Friends,

          I want to manage link file worksets open/close, thus I use WorksetConfiguration and RevitLinkType.LoadFrom() to Reload link files in current rvt, but it always makes Revit crash 😞

          I try some methods according to previous Forum records, but all failed...

          Here is my codes:

    foreach (var key in result.Keys)
    {
          var linkdoc = key;
          var openids = result[key].OpenedList.Select(x => x.Id).ToList();
          var closeids = result[key].ClosedList.Select(x => x.Id).ToList();

          var config = new WorksetConfiguration();
          if (openids != null && openids.Any())
          {
                config.Open(openids);
          }
          if (closeids != null && closeids.Any())
          {
                config.Close(closeids);
          }

          var mp = ModelPathUtils.ConvertUserVisiblePathToModelPath(linkdoc.PathName);
          var rlt = rvtlinktypes.FirstOrDefault(x => x.Name.Equals(linkdoc.Title)) as RevitLinkType;
          rlt.LoadFrom(mp, config);
  }

         I hope that you can help me,  many thanks!

I solved this issue by myself, haha ~~

I found that RevitLinkType.LoadFrom() is not always successful to change link file workset open/close.

Thus, I use this way:

foreach (var key in result.Keys)
{
    var linkpath = key;
    var openids = result[key].OpenedList.Select(x => x.Id).ToList();
    var closeids = result[key].ClosedList.Select(x => x.Id).ToList();

    var config = new WorksetConfiguration(WorksetConfigurationOption.CloseAllWorksets);
    if (openids != null && openids.Any())
    {
          config.Open(openids);
    }

    var filePath = new FileInfo(linkpath);
    var mp = ModelPathUtils.ConvertUserVisiblePathToModelPath(filePath.ToString());
    var linktitle = Path.GetFileName(linkpath);
    var rlt = rvtlinktypes.FirstOrDefault(x => x.Name.Equals(linktitle)) as RevitLinkType;

    doc.Delete(rlt.Id);
    doc.Regenerate();
    RevitLinkOptions option = new RevitLinkOptions(true);
    option.SetWorksetConfiguration(config);
    RevitLinkType.Create(doc, mp, option);
}

Remember that it should run in transaction

Wish it is helpful for everybody

I recommend that a Autodesk Help Link:Autodesk Revit 2014 Help ，

it gave me a lot of Inspirations about link file workset configuration operation.

Wish it is helpful for everyone 🙂

Thank you for posting this, I'm struggling with this same issue.

I'm having a bit of trouble understanding the linkpath that you sent to the mp. Is this the path of the RevitLinkType? How do you access it? I have a filtered element collector of my RevitLinkTypes, and I'm accessing each element with the iterator 'e'. Can I just use FileInfo(e)?

For the record, I managed to get this working in Python using the following code:
