導出excel小結(C#,.NET,Wpf)

 做項目時收集的一些資料，分享一下，希望對大家有用

 

常用的一些操作

range.NumberFormatLocal = "@"; //設置單元格格式爲文本 range = (Range)worksheet.get_Range("A1", "E1"); //獲取Excel多個單元格區域：本例做爲Excel表頭 range.Merge(0); //單元格合併動作 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; //設置字體是否有下劃線 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; //設置單元格上邊框爲無邊框 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; //填充顏色爲淡紫色 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

 

Excel 行高,列寬,合併單元格,單元格邊框線,凍結

在Excel中設置背景字體及其它顏色的時候用的都是索引

如： xSt.get_Range(excel.Cells[2, i], excel.Cells[2, i]).Font.ColorIndex = 5

特此提供一個對應的Excel顏色索引圖例

還有就是可能是大家最關心的Excel.exe的問題了，分享我們項目中的幾個釋放進程的方法，希望對大家有用，都是絕對好使的

方法1

 #region 釋放excel.exe [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)] static extern int GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId); public void KillSpecialExcel() { try { if (excel != null) { int lpdwProcessId; GetWindowThreadProcessId(new IntPtr(excel.Hwnd), out lpdwProcessId); System.Diagnostics.Process.GetProcessById(lpdwProcessId).Kill(); } } catch (Exception ex) { Console.WriteLine("Delete Excel Process Error:" + ex.Message); } } #endregion

 

方法2

#region KillAllExcel public bool KillAllExcel() { try { if (m_objExcel != null) { m_objExcel.Quit(); System.Runtime.InteropServices.Marshal.ReleaseComObject(m_objExcel); //釋放COM組件，其實就是將其引用計數減1 //System.Diagnostics.Process theProc; foreach (System.Diagnostics.Process theProc in System.Diagnostics.Process.GetProcessesByName("EXCEL")) { //先關閉圖形窗口。如果關閉失敗...有的時候在狀態裏看不到圖形窗口的excel了， //但是在進程裏仍然有EXCEL.EXE的進程存在，那麼就需要殺掉它 if (theProc.CloseMainWindow() == false) { theProc.Kill(); } } m_objExcel = null; return true; } } catch { return false; } return true; } #endregion
