c#利用office组件导出

Microsoft.Office.Interop.Excel.Application excel1 = new Microsoft.Office.Interop.Excel.Application();

Worksheet worksheet1= (Worksheet)excel1.Worksheets[1];

Microsoft.Office.Interop.Excel.Range range = worksheet1.Range[worksheet1.Cells[4, 1], worksheet1.Cells[8, 1]];//获取Excel多个单元格区域

1.合并单元格

range.Merge(0);//单元格合并动作

worksheet1.Cells[4, 1] = "项目";//为合并的单元格赋值

---------

2.给单元格加边框

//内外边框都显示

range.Borders.LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous;

range.Borders.Weight = 3;//边框线的粗细

//只显示外边框

range.BorderAround(XlLineStyle.xlContinuous, XlBorderWeight.xlMedium, XlColorIndex.xlColorIndexAutomatic, System.Drawing.Color.Black.ToArgb());

---------

3.设置单元格的宽度，和自动调整列宽

excelRange.ColumnWidth = 15;//设置单元格的宽度

rang.EntireColumn.AutoFit();//自动调整列宽

---------

4.设置背景填充颜色

range.Interior.ColorIndex = 8;

---------

5.其他小设置

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range.Borders.LineStyle=1; //设置单元格边框的粗细

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
