Revit二次开发--取得Revit版本号

在Revit插件开发过程中有时需要提取Revit版本号：

  public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
    {
        m_productName = commandData.Application.Application.VersionName;
        m_version = commandData.Application.Application.VersionNumber;
        m_buildNumber = commandData.Application.Application.VersionBuild;
        return Result.Succeeded;
    }
