}
}
//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[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]);
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="000000"//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+3, DT.Columns.Count - 3],mySheet.Cells[i + 3, DT.Columns.Count -3]).get_Characters(a.Length+ 1,b.Length).Font.Subscript =true;//控制输出样式为下标
mySheet.get_Range(mySheet.Cells[i+3, DT.Columns.Count - 3],mySheet.Cells[i + 3, DT.Columns.Count-3]).get_Characters(a.Length + b.Length+ 1, 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=7,
枚举XLVAlign的值还有：
// 靠上对齐
xlVAlignTop,
//两端对齐.
xlVAlignJustify=-4130,
//分散对齐.
xlVAlignDistributed,
//居中对齐.
xlVAlignCenter,
//靠下对齐.
xlVAlignBottom=-4107,
D、 单元格边框设置；
//设置边框
Excel.Range r =mySheet.get_Range(mySheet.Cells[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]);
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[1,1],myExcel.Cells[1,4]).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[1,1],myExcel.Cells[1,1]).Font.Bold =true;
//设置字体大小
myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Size=16;
//设置字体的颜色
myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.ColorIndex = 3;
//设置字体
myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Name ="隶书";
//设置成斜体
myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).Font.Italic =true;
//设置下划线
myExcel.get_Range(myExcel.Cells[1,1],myExcel.Cells[1,1]).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[3,1],myExcel.Cells[3,1]).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 = 1; i < DT.Columns.Count- 2; i += 2)
{
Sheet.get_Range(Sheet.Rows.Cells[i,1],Sheet.Rows.Cells[i, DT.Columns.Count - 3]).Interior.set_ColorIndex(2); //设置行的颜色
}
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.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=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
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[1];
Excel.WorksheetmySheet = (Excel.Worksheet)myBook.Worksheets[1];
Excel.Ranger = mySheet.get_Range(mySheet.Cells[1,1],mySheet.Cells[DT.Rows.Count + 2,DT.Columns.Count - 3]);
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[1,1]= "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 = 0; i <DT.Columns.Count - 3; i++)
{
myExcel.Cells[2,1+ 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();
