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.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb();     //设置单元格的背景色
 
range.Borders.LineStyle=1;     //设置单元格边框的粗细
 
range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb());     //给单元格加边框
 
range.Borders.get_Item(Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeTop).LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlLineStyleNone; //设置单元格上边框为无边框
 
range.EntireColumn.AutoFit();     //自动调整列宽
 
Range.HorizontalAlignment= xlCenter;     // 文本水平居中方式
 
Range.VerticalAlignment= xlCenter     //文本垂直居中方式
