[CONNECT C# Addin] LevelHandle.Name throws Access Violation

I'm using the following code to determine the level name of an element. The code is encountering a System.AccessViolationException when I use the LevelHandle.Name to retrieve the level name. Works fine on some elements, but throws this exception on others. The code doesn't actually catch the exception due to the unmanaged nature of the application throwing the exception (CONNECT) but if I watch the code blow up in the debugger the evaluation of the levelname shows the exception.

///<summary>Gets the level of an Element.</summary>

///<param name="element">The source element from which to retrieve the level name.</param>

///<returns>The level name that the element is on.</returns>

publicstaticstring GetElementLevelName(Element element)

{

// Get Element Property Getter

ElementPropertiesGetter elementPropertiesGetter = newElementPropertiesGetter(element);

// Get DGN Model element belongs to

DgnModel dgnModel = element.DgnModel;

// Get DGN File

DgnFile dgnFile = dgnModel.GetDgnFile();

// Get File Level Cache

FileLevelCache fileLevelCache = dgnFile.GetLevelCache();

// Get Level Id

LevelId levelId = elementPropertiesGetter.Level;

// Get Level Handle

LevelHandle levelHandle = fileLevelCache.GetLevel(levelId, true);

// Return Level Name

string levelName;

try

{

levelName = levelHandle.Name;

}

catch (System.AccessViolationException)

{

levelName = "";

throw;

}

return levelName;

}
