using Excel = Microsoft.Office.Interop.Excel;

定义

1 Excel.ApplicationClass app;
2 Excel.Workbooks books;
3 Excel.Workbook book;
4 Excel.Sheets sheets;
5 Excel.Worksheet sheet;
6 Excel.Range m_objRange;
7 object missing = System.Reflection.Missing.Value;

读取有效单元格区域

 1 foreach (Excel.Worksheet sheet in book.Sheets)
 2 {
 3     for (int i = 1; i <= sheet.UsedRange.Cells.Rows.Count; i++)
 4     {
 5         for (int j = 1; j <= sheet.UsedRange.Cells.Columns.Count; j++)
 6         {
 7             Excel.Range m_objRange = (Excel.Range)sheet.Cells[i, j];
 8         }
 9     }
10 }

单元格区域赋值

1 m_objRange = sheet .get_Range("A1"，missing ); 
2 m_objRange.set_Value(missing , "单元格的值");

单元格区域设置Excel公式

1 m_objRange = sheet .get_Range("A1", missing ); 
2 m_objRange.set_Value(missing , "=SUM(A2:A5)");

字体加粗

1 m_objRange.Font.Bold = true;

设置数字格式

1 //保留2位小数
2 m_objRange.NumberFormat = "0.00";

设置边框

1 m_objRange = sheet .get_Range("A1", "B2");
2 //设置边框粗细
3 m_objRange.Borders.Weight = 2;
4 //设置边框样式
5 m_objRange.Borders.get_Item(Excel.XlBordersIndex.xlEdgeTop).LineStyle = Excel.XlLineStyle.xlDouble;
