生成excel的時候有時候需要設置單元格的一些屬性,可以參考一下:
1 range.NumberFormatLocal = "@"; //設置單元格格式為文本 2 ange.get_Range("B1","B"+dataGridView2.RowCount+1).NumberFormat = "yyyy-m-d hh:mm:ss"; //時間格式的設置 3 range = (Range)worksheet.get_Range("A1", "E1"); //獲取Excel多個單元格區域：本例做為Excel表頭 4 range.Merge(0); //單元格合並動作 5 worksheet.Cells[1, 1] = "Excel單元格賦值"; //Excel單元格賦值 6 range.Font.Size = 15; //設置字體大小 7 range.Font.Underline=true; //設置字體是否有下划線 8 range.Font.Name="黑體"; 設置字體的種類 9 range.HorizontalAlignment=XlHAlign.xlHAlignCenter; //設置字體在單元格內的對其方式 10 range.ColumnWidth=15; //設置單元格的寬度 11 range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb(); //設置單元格的背景色 12 range.Borders.LineStyle=1; //設置單元格邊框的粗細 13 range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb()); //給單元格加邊框 14 range.EntireColumn.AutoFit(); //自動調整列寬 15 Range.HorizontalAlignment= xlCenter; // 文本水平居中方式 16 Range.VerticalAlignment= xlCenter //文本垂直居中方式 17 Range.WrapText=true; //文本自動換行 18 Range.Interior.ColorIndex=39; //填充顏色為淡紫色 19 Range.Font.Color=clBlue; //字體顏色 20 xlsApp.DisplayAlerts=false; //保存Excel的時候，不彈出是否保存的窗口直接進行保存 21 workbook.SaveCopyAs(temp);///填入完信息之后另存到路徑及文件名字
注：要添加COM組件 Microsoft Excel 11.0 Object Library 引用。
具體代碼如下：
