Revit二次开发_将数据导入Excel

有时需要将Revit模型的一些信息提取到Excel中进行处理或者是作为记录进行储存，但也许是因为Revit的数据结构相对复杂，并不支持直接将数据导出Excel，所以平时通过二次开发将信息输出到Excel中。

常使用的输出方法有三个，分别是com组件；NPOI库；Epplus库。

com组件需要电脑安装Excel软件，由于Excel版本比较多，导出的时候要注意版本的问题。下面的代码通过com组件的方法导出模型中的一张明细表。

//使用Excel2013，引用Microsoft Excel 15.0 Object Library

using EXCEL = Microsoft.Office.Interop.Excel;

    class ViewScheduleExport : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            Document document = commandData.Application.ActiveUIDocument.Document;

            //获取项目中的一张门明细表
            FilteredElementCollector collector = new FilteredElementCollector(document);
            foreach (ViewSchedule vs in collector.OfClass(typeof(ViewSchedule)))
            {
                if (vs.Name == "门明细表")
                {
                    //Excel文件路径
                    string path = @"D:\LST\Test\ViewSchedule.xlsx";
                    //如文件已存在则删除

                    EXCEL.Worksheet excelWorkSheet = excelWorkBook.Sheets[1] as EXCEL.Worksheet;

                    //获取表格的行列数
                    int rows, cols;

                    {
                        for(int j = 0; j < cols; j++)
                        {
                            EXCEL.Range cell = excelWorkSheet.Cells[i + 1, j + 1] as EXCEL.Range;

                            //获取明细表中的字符串

                            {
                                cell.Font.Bold = true;
                            }
                            //添加边框线
                            cell.BorderAround2();
                        }
                    }

                    //保存文件
                    excelWorkBook.Close(true, path);
                    excelApplication.Quit();
                    excelApplication = null;

                    continue;
                }
            }

            return Result.Succeeded;

NPOI与Epplus都是开源免费的，NPOI库用的比较少，因为它只支持03和07版的Excel，但它不需要电脑安装有Excel软件。下面的代码读取模型中的建筑标高，然后通过NPOI库在Excel中制作一个层高表。

Epplus库也不需要电脑安装Excel，但只支持xlsx格式的excel文件，网上的一些评论是导出的效率及稳定性都比NPOI好，但由于没进行过非常大数据量的导出，所以暂时没有体现出来。 下面代码将模型中的管道信息按照一定的规则处理后导出到Excel中，然后在Excel中简单的做个数据透视即可获得对应的工程量。
