一、对行高，列宽、单元格边框等的设置
private _Workbook _workBook = null;
private Worksheet _workSheet = null;
private Excel.Application _excelApplicatin = null;
_excelApplicatin = new Excel.Application();
_excelApplicatin.Visible = true;
_excelApplicatin.DisplayAlerts = true;
_workBook = _excelApplicatin.Workbooks.Add(XlSheetType.xlWorksheet);
_workSheet = (Worksheet)_workBook.ActiveSheet;
_workSheet.Name = "workSheetName";
//打开已存在的Excel
string strExcelPathName = AppDomain.CurrentDomain.BaseDirectory + "excelSheetName.xls";
Excel.Workbook workBook = application.Workbooks.Open(strExcelPathName, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
<br>//读取已打开的Excel
Excel.Worksheet workSheet1 = (Excel.Worksheet)workBook.Sheets["SheetName1"];
Excel.Worksheet workSheet2 = (Excel.Worksheet)workBook.Sheets["SheetName2"];
//添加一个workSheet
Worksheet workSheet = (Worksheet)workBook.Worksheets.Add(System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing);
//RowHeight "1:1"表示第一行, "1:2"表示,第一行和第二行
((Excel.Range)_workSheet.Rows["1:1", System.Type.Missing]).RowHeight = 100;
//ColumnWidth "A:B"表示第一列和第二列, "A:A"表示第一列
((Excel.Range)_workSheet.Columns["A:B", System.Type.Missing]).ColumnWidth = 10;
// EXCEL操作(需要冻结的字段 按住ALT+W 再按F)
Excel.Range excelRange = _workSheet .get_Range(_workSheet .Cells[10, 5], _workSheet .Cells[10, 5]);
excelRange.Select();
excelApplication.ActiveWindow.FreezePanes = true;
//Borders.LineStyle 单元格边框线
Excel.Range excelRange = _workSheet.get_Range(_workSheet.Cells[2, 2], _workSheet.Cells[4, 6]);
//单元格边框线类型(线型,虚线型)
excelRange.Borders.LineStyle = 1;
excelRange.Borders.get_Item(XlBordersIndex.xlEdgeTop).LineStyle = Excel.XlLineStyle.xlContinuous;
//指定单元格下边框线粗细,和色彩
excelRange.Borders.get_Item(XlBordersIndex.xlEdgeBottom).Weight = Excel.XlBorderWeight.xlMedium;
excelRange.Borders.get_Item(XlBordersIndex.xlEdgeBottom).ColorIndex =3;
//设置字体大小
excelRange.Font.Size = 15;
//设置字体是否有下划线
excelRange.Font.Underline = true;
//设置字体在单元格内的对其方式
excelRange.HorizontalAlignment = XlHAlign.xlHAlignCenter;
//设置单元格的宽度
excelRange.ColumnWidth = 15;
//设置单元格的背景色
excelRange.Cells.Interior.Color = System.Drawing.Color.FromArgb(255, 204, 153).ToArgb();
// 给单元格加边框
excelRange.BorderAround(XlLineStyle.xlContinuous, XlBorderWeight.xlThick,
XlColorIndex.xlColorIndexAutomatic, System.Drawing.Color.Black.ToArgb());<br>
//自动调整列宽
excelRange.EntireColumn.AutoFit();
// 文本水平居中方式
excelRange.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;
//文本自动换行
excelRange.WrapText = true;
//填充颜色为淡紫色
excelRange.Interior.ColorIndex = 39;
//合并单元格
excelRange.Merge(excelRange.MergeCells);
_workSheet.get_Range("A15", "B15").Merge(_workSheet.get_Range("A15", "B15").MergeCells);

for (int i = 5; i < countRow + 1; i++)
{
string strKB = null;
Microsoft.Office.Interop.Excel.Range kbrng = (Microsoft.Office.Interop.Excel.Range)sheSource.Cells[i, 1];
if (kbrng.Value2 != null)
strKB = kbrng.Value2.ToString();
if (strTotal.Contains(strKB))
kbrng.Interior.ColorIndex = 3;
}
二、常见的Excel单元格格式设置内容
1、 数字(Range.NumberFormatlocal 属性)
常规：
Range.NumberFormatlocal = "G/通用格式"
数值：
Range.NumberFormatlocal = "0.000_" --保留小 数位数为3 (此处“_”表示：留下一个与下一个字符同等宽度的空格)
Range.NumberFormatlocal = "0" --不要小数
Range.NumberFormatlo cal = "#,##0.000" --保留小数位数为3，并使用千位分隔符
货币：
Range.NumberFormatlocal = "RMB]G/通用格式"---人民币大写
2、 对齐
水平对齐：Range.HorizontalAlignment = etHAlignCenter ---居中
垂 直对齐：Range.VerticalAlignment = etVAlignCenter---居中
是否自动换行：Range.WrapText = True
是否缩小字体填充：Range.ShrinkToFit = True
是否合并单元格：Range.MergeCells = False
文字竖排：Range.Orientation = etVertical
文字倾斜度数：Range.Orientation = 45 -----倾斜45度
字体（Font对象）
字体名称：Font.Name = "华文行楷"
字形： Font.FontStyle = "常规"
字号：Font.Size = "10"
下划线：Font.Strikethrough = True; Font.Underline = etUnderlineStyleDouble ---双下划线
上标：Font.Superscript = True
下 标：Font.SubScript = True
删除线：Font.OutlineFont = True
3、 边框（Borders对象）
Borders.Item(etEdgeTop)：上边框
Borders.Item(etEdgeLeft)：左边框
Borders.Item (etEdgeRight)：右边框
Borders.Item(etEdgeBottom)：下边框
Borders.Item(etDiagonalDown) ：左上--右下边框
Borders.Item(etDiagonalUp)：左下--右上边框
Border.LineStyle = etContinuous 线条样式
