c#中设置Excel格式 Excel对象形式

 

生成excel的时候有时候需要设置单元格的一些属性,可以参考一下: 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

 

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.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

 

Range.WrapText=true; //文本自动换行

 

Range.Interior.ColorIndex=39; //填充颜色为淡紫色

 

Range.Font.Color=clBlue; //字体颜色

 

xlsApp.DisplayAlerts=false; //保存Excel的时候，不弹出是否保存的窗口直接进行保存

 

workbook.SaveCopyAs(temp);///填入完信息之后另存到路径及文件名字

 

 

 

注：要添加COM组件 Microsoft Excel 11.0 Object Library 引用。

 

具体代码如下：

using System.Collections.Generic;

 

using System.Text;

 

using System.Data.SqlClient;
