C#操作Excell常用方法

這是在博客園看的文章，寫的很好，所以轉一下，方便自己以后用到的時候可以隨時查看。

操作range類需要在項目中引用兩個dll，不然點不出來，分別是：

microsoft office XX.0 Object Library

microsoft excelXX.0 Object Library

----------------------------------------------------------------------分割線

range.NumberFormatLocal = "@";     //設置單元格格式為文本


range = (Range)worksheet.get_Range("A1", "E1");     //獲取Excel多個單元格區域：本例做為Excel表頭

range.Merge(0);     //單元格合並動作

worksheet.Cells[1, 1] = "Excel單元格賦值";     //Excel單元格賦值

range.Font.Size = 15;     //設置字體大小

range.Font.Underline=true;     //設置字體是否有下划線

range.Font.Name="黑體";      設置字體的種類

range.HorizontalAlignment=XlHAlign.xlHAlignCenter;     //設置字體在單元格內的對其方式

range.ColumnWidth=15;     //設置單元格的寬度

range.Cells.Interior.Color=System.Drawing.Color.FromArgb(255,204,153).ToArgb();     //設置單元格的背景色

range.Borders.LineStyle=1;     //設置單元格邊框的粗細

range.BorderAround(XlLineStyle.xlContinuous,XlBorderWeight.xlThick,XlColorIndex.xlColorIndexAutomatic,System.Drawing.Color.Black.ToArgb());     //給單元格加邊框

range.Borders.get_Item(Microsoft.Office.Interop.Excel.XlBordersIndex.xlEdgeTop).LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlLineStyleNone; //設置單元格上邊框為無邊框

range.EntireColumn.AutoFit();     //自動調整列寬

Range.HorizontalAlignment= xlCenter;     // 文本水平居中方式

Range.VerticalAlignment= xlCenter     //文本垂直居中方式

Range.WrapText=true;     //文本自動換行

Range.Interior.ColorIndex=39;     //填充顏色為淡紫色

Range.Font.Color=clBlue;     //字體顏色

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
