    1.例子导出Excel的样式

    样式代码

    public void Exportdatagridviewtoexcel(string Textname)

                }

    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
