range.NumberFormatLocal = "@"; //设置单元格格式为文本

range = (Range)worksheet.get_Range("A1", "E1"); //获取Excel多个单元格区域：本例做为Excel表头

range.Merge(0); //单元格合并动作

worksheet.Cells[1, 1] = "Excel单元格赋值"; //Excel单元格赋值

range.Font.Size = 15; //设置字体大小

range.Font.Underline=true; //设置字体是否有下划线

range.Font.Name="黑体"; 设置字体的种类

range.HorizontalAlignment=XlHAlign.xlHAlignCenter; //设置字体在单元格内的对其方式

range.ColumnWidth=15; //设置单元格的宽度

range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb(); //设置单元格的背景色
