不安装excel使用c#创建excel文件

//创建excel

Excel.Application app = new Excel.Application();
app.Application.Workbooks.Add(true);
Excel.Workbook book = (Excel.Workbook)app.ActiveWorkbook;
Excel.Worksheet sheet = (Excel.Worksheet)book.ActiveSheet;

需要引用com里的Microsoft Excel 14.0 Object Libary(其它版本方法大致相同)

当然就意味着做这件事情就必须安装office Excel,

如果需要饶过office Excel那么就看我最后的实现方法吧~!

我最后的实现是使用的第三方Aspose.Cells.dll

具了解这个dll一直免费,(第三方有风险,使用需谨慎)

//创建excel
Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook();
Aspose.Cells.Worksheet sheet = workbook.Worksheets[0];
sheet.FreezePanes(1, 1, 1, 0);//冻结第一行
