                //worksheet.get_Range(worksheet.Cells[1, 1], worksheet.Cells[2, 8]).Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeRight].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThick;

                if (savedialog.FileName != "")

                {

                    try

                    {

                        workbook.Saved = true;

                        workbook.SaveCopyAs(savedialog.FileName);

                    }

                    catch (Exception ex)

                    {

                        MessageBox.Show("导出文件时出错,文件可能正被打开！..." + ex.Message, "系统提示 ", MessageBoxButtons.OK, MessageBoxIcon.Error);

                    }

                }

                //GC.Collect();//强行销毁

                MessageBox.Show("数据导出成功！ ", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

2.单元格样式设置

Excel.Range r =mySheet.get_Range(mySheet.Cells[,],mySheet.Cells[DT.Rows.Count + ,DT.Columns.Count - ]);

r.NumberFormat="@";  //设置单元格格式为文本类型，文本类型可设置上下标

r.NumberForma="0.00_ "//设置单元格格式为数值类型，小数点后2位

r.NumberForma="￥#,##0.00;￥-#,##0.00"//设设置单元格格式为货币类型，小数点后2位

r.NumberForma=_"_ ￥*#,##0.00_;_ ￥*-#,##0.00_ ;_ ￥*""-""??_;_ @_ "//置单元格格式为会计专用类型，小数点后2位

r.NumberForma="yyyy-m-d"//设置单元格格式为日期类型

r.NumberForma="[$-F400]h:mm:ss AM/PM"//设置单元格格式为时间类型

r.NumberForma="0.00%"//设置单元格格式为百分比类型，小数点后2位

r.NumberForma="# ?/?"设置单元格格式为分数类型，分母为一位数

r.NumberForma="0.00E+00"//设置单元格格式为科学技术类型，小数位数为2

r.NumberForma=""//设置单元格格式为特殊类型

B、上下标格式的控制；

mySheet.get_Range(mySheet.Cells[i+, DT.Columns.Count - ],mySheet.Cells[i + , DT.Columns.Count -]).get_Characters(a.Length+ ,b.Length).Font.Subscript =true;//控制输出样式为下标

mySheet.get_Range(mySheet.Cells[i+, DT.Columns.Count - ],mySheet.Cells[i + , DT.Columns.Count-]).get_Characters(a.Length + b.Length+ , c.Length).Font.Superscript =true; //控制输出样式为上标

C、单元格水平垂直对齐方式；

//单元格水平，垂直居中

r.HorizontalAlignment=Excel.XlHAlign.xlHAlignCenter;

r.VerticalAlignment=Excel.XlVAlign.xlVAlignCenter;

上面代码中，枚举XLHAlign的值还有：

// 右对齐

xlHAlignRight,

// 左对齐.

xlHAlignLeft,

// 两端对齐.

xlHAlignJustify,

// 分散对齐(缩进)

xlHAlignDistributed,

// 居中对齐

xlHAlignCenter,

// 依照数据类型对齐,常规

xlHAlignGeneral,

// 填充

xlHAlignFill,

// 跨列对齐.

xlHAlignCenterAcrossSelection=,

枚举XLVAlign的值还有：

// 靠上对齐

xlVAlignTop,

//两端对齐.

xlVAlignJustify=-,

//分散对齐.

xlVAlignDistributed,

//居中对齐.

xlVAlignCenter,

//靠下对齐.

xlVAlignBottom=-,

D、 单元格边框设置；

//设置边框

Excel.Range r =mySheet.get_Range(mySheet.Cells[,],mySheet.Cells[DT.Rows.Count + ,DT.Columns.Count - ]);

r.Borders.LineStyle=Excel.XlLineStyle.xlContinuous;

枚举XlLineStyle中还有下面线形：

//没边框线

xlLineStyleNone,

//双线.

xlDouble,

//点状线.

xlDot,

//虚线.

xlDash,

//连续线.

xlContinuous,

//点线交互型

xlDashDot,

//两点一线型

xlDashDotDot,

//斜线.

xlSlantDashDot,

E、单元格合并 

用get_Range方法获取要合并的单元格，再设置MergeCells属性的值进行合并。

代码：

//合并单元格

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).MergeCells =true;

F、字体设置

先用get_Range方法选中要设置字体的某个单元格或者或者直接用get_Characters方法直接选中要设置的字符进行设置；

代码：

//加粗字体

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.Bold =true;

//设置字体大小

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.Size=;

//设置字体的颜色

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.ColorIndex = ;

//设置字体

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.Name ="隶书";

//设置成斜体

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.Italic =true;

//设置下划线

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Font.Underline =true;

G、冻结行列 

用get_Range方法获取单元格，再设置其Freezepanes属性为true，就把该单元格右上方的行和列都冻结了，取消冻结将其值设为false即可。

//冻结行列

myExcel.get_Range(myExcel.Cells[,],myExcel.Cells[,]).Activate();

myExcel.ActiveWindow.FreezePanes=true;

H、 公式输入栏的隐藏

//设置是否显示Excel公式输入栏，默认为true

myExcel.DisplayFormulaBar=false;

I、 列标题与行标题的隐藏

//设置是否显示行和列的标题，默认为true

myExcel.ActiveWindow.DisplayHeadings=false;

J、网格的隐藏

//设置是否显示网格，默认为true

myExcel.ActiveWindow.DisplayGridlines=false;

K、 水平、垂直滚动条的隐藏

//设置是否显示水平滚动条

myExcel.ActiveWindow.DisplayHorizontalScrollBar=false;

//设置是否显示垂直滚动条

myExcel.ActiveWindow.DisplayVerticalScrollBar=false;

L、页的隐藏Sheet

//设置是否显示Sheet页

myExcel.ActiveWindow.DisplayWorkbookTabs=false;

M、 电子表格外观控制：

Sheet.DisplayToolbar= false;//是否显示工具栏默认值为 true

Sheet.DisplayOfficeLogo=  false;// 取消显示Office图标

Sheet.DisplayColumnHeadings=  false;// 是否显示列标题，默认是true

Sheet.DisplayRowHeadings=  false;// 是否显示行标题，默认是true

Sheet.DisplayHorizontalScrollBar=  false;// 是否显示水平滚动条，默认为true

Sheet.DisplayVerticalScrollBar=  false;// 是否显示垂直滚动条，默认为true

Sheet.DisplayGridlines=  false;// 电子表格是否显示网格，默认为true

for (int i = ; i < DT.Columns.Count- ; i += )

{

Sheet.get_Range(Sheet.Rows.Cells[i,],Sheet.Rows.Cells[i, DT.Columns.Count - ]).Interior.set_ColorIndex(); //设置行的颜色

}

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

 range.Font.Size = ; //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=; //设置单元格的宽度

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

range.Borders.LineStyle=; //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

 Range.WrapText=true; //文本自动换行

Range.Interior.ColorIndex=; //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

向Excel中填充数据，并保存为临时文件

Excel.ApplicationmyExcel =newExcel.Application();

//打开模板文件

myExcel.Application.Workbooks.Open(mode.FullName,missing,missing,missing, missing, missing, missing, missing, missing,missing, missing,missing,missing, missing, missing);

//选中有数据的Cells

Excel.WorkbookmyBook = myExcel.Workbooks[];

Excel.WorksheetmySheet = (Excel.Worksheet)myBook.Worksheets[];

Excel.Ranger = mySheet.get_Range(mySheet.Cells[,],mySheet.Cells[DT.Rows.Count + ,DT.Columns.Count - ]);

r.Select();

//不单独显示Excel，最后在IE中显示

myExcel.Visible=false;

//第一行为报表的标题

myExcel.Cells[,]= "用模板导出的报表";

//逐行写入数据，数组中第一行为报表的列标题

for (int i = ; i <DT.Columns.Count - ; i++)

{

myExcel.Cells[,+ i] =DT.Columns[i].Caption; ;

}

//在当前目录下指定一个临时文件

string FileName =Server.MapPath("~")+"""Temp.xls";

if (File.Exists(FileName))

{

File.Delete(FileName);

}

myExcel.Save(FileName);

mySheet.Cells.Clear();

//设置不出现保存提示框

myBook.Saved=true;

myExcel.Application.Workbooks.Close();
