基于.NET的Excel开发：单元格区域的操作（读取、赋值、边框和格式）

• 引用

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;

• XlLineStyle枚举

• XlBordersIndex枚举
