將二維數組插入到C＃中的excel中WPF

Question

我想插入String[][]（二維數組）以代替「逐個單元格」或Row的excel。

另一件事： 我想打開一個模板XLS文件，寫入它並用另一個名稱保存它。 我試圖搜索谷歌已經2天了。

請幫我:-)

（在C＃WPF）

Answer 1

我正在使用對象終於沒有[，]，並插入RO通過

 xlApp = new Excel.Application(); 

     xlWorkBook = xlApp.Workbooks.Open(ExcelFile); 
     xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); 

     Excel.Range firstCell = xlWorkSheet.get_Range("A1", Type.Missing); 

     Excel.Range lastCell = xlWorkSheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell, Type.Missing); 


     Excel.Range worksheetCells = xlWorkSheet.get_Range(firstCell, lastCell); 

     int rowCount = worksheetCells.Rows.Count; 
     int colCount = worksheetCells.Columns.Count; 

     object[,] cellFormulas = new String[rowCount, colCount]; 

     cellFormulas = worksheetCells.Formula as object[,]; 

     // String[][] ResultMatrix = new String[rowCount][]; 



     xlWorkBook.Close(true, misValue, misValue); 
     xlApp.Workbooks.Close();'

我能解決的第一個問題是：

我要插入的String [] []（二維數組）來改爲「逐個細胞」或Row。

在第一你應該String[][]轉換爲String[,]，然後使用這個（我測試）：

 public static void ExportToExcel(String[,] data, String sheetName, String path) 
     { 
      var dt = new DataTable(); 

      for (var row = 0; row < data.GetLength(0); ++row) 
      { 
       for (var col = 0; col < data.GetLength(1); col++) 
       { 
        dt.Rows[row][col] = data[row, col]; 
       } 
      } 

      Excel.Application oXL; 
      Excel.Workbook oWB; 
      Excel.Worksheet oSheet; 
      //Excel.Range oRange; 

      oXL = new Excel.Application(); 

      oXL.Visible = true; 
      oXL.DisplayAlerts = false; 

      oWB = oXL.Workbooks.Add(Missing.Value); 

      oSheet = (Excel.Worksheet)oWB.ActiveSheet; 
      oSheet.Name = sheetName; 

      var rowCount = 1; 

      foreach (DataRow dr in dt.Rows) 
      { 
       rowCount += 1; 
       for (var i = 1; i < dt.Columns.Count + 1; i++) 
       { 
        if (rowCount == 2) 
        { 
         oSheet.Cells[1, i] = dt.Columns[i - 1].ColumnName; 
        } 
        oSheet.Cells[rowCount, i] = dr[i - 1].ToString(); 
       } 
      } 

      oSheet = null; 
      oWB.SaveAs(path, Excel.XlFileFormat.xlWorkbookNormal, 
       Missing.Value, Missing.Value, Missing.Value, Missing.Value, 
       Excel.XlSaveAsAccessMode.xlExclusive, 
       Missing.Value, Missing.Value, Missing.Value, 
       Missing.Value, Missing.Value); 
      oWB.Close(Missing.Value, Missing.Value, Missing.Value); 
      oWB = null; 

      oXL.Quit(); 

      GC.WaitForPendingFinalizers(); 
      GC.Collect(); 
      GC.WaitForPendingFinalizers(); 
      GC.Collect(); 
     } 

注：應使用在你引用添加的Microsoft.Office.Interop.Excel。

你想要的東西，如：

雖然我認爲它只會在交錯數組，而不是二維數組。未在2d陣列上測試。

var startCell = Worksheet.Cells[row, col]; 
var endCell = Worksheet.Cells[row, col]; 
var writeRange = (Excel.Range)Worksheet.Cells[startCell, endCell]; 
writeRange.Value = myArray;
