写在两个不同的工作表上不起作用excel 2007

Question

我有一个问题，我需要在excel上写一些信息。

我可以在两个工作表之一（“worksheet”）上正确书写，而在另一个工作表（“worksheet2”）上，它什么也没写，我不知道为什么。所有的过程都是一样的，但它不写任何东西。

我把我的代码放在下面，希望对你有帮助：

var excelApp = new Microsoft.Office.Interop.Excel.Application();
        excelApp.Workbooks.Open(destFile);
        Microsoft.Office.Interop.Excel.Worksheet worksheet = excelApp.Worksheets.get_Item(2);
        Microsoft.Office.Interop.Excel.Worksheet worksheet2 = excelApp.Worksheets.get_Item(1);
        excelApp.Visible = false;

        var data = new object[numRows, numColumns];
        int contadorMedidas = 0;
        //int primeraVez = 0;
        for (int i = 1; i <= numRows; i++)  // assuming the data starts at 1,1
        {
            for (int j = 1; j <= numColumns; j++)
            {
                if (contadorMedidas < contents.Count)
                {
                    worksheet.Cells[i, j] = contents[contadorMedidas];
                    contadorMedidas++;
                }
            }
        }

        //Escribir en la hoja de pautas el nombre y los valores de codigo y plano
        //Codigo
        worksheet2.Cells[2, 5] = codigo;
        //Plano
        worksheet2.Cells[3, 4] = plano;
        //Trabajador
        worksheet2.Cells[6, 2] = cbxWorker.Text;
        //Si es BR, hay que añadir un código extra:
        if (br)
        {
            for (int i = 0; i < numRows; i++)
            {
                worksheet2.Cells[8 + i, 6] = "7525SI-0203-FA"; 
            }
        }

        excelApp.Quit();

我注意到你的代码当它要写到工作表2时，你有一个条件。也许这个条件是假的，这就是它没有写入工作表2的原因。

if (br)
{
    //write to worksheet2
}

否则，我使用以下代码并能够在同一个 Excel 工作簿中的两个工作表上进行书写。 希望这会有所帮助。

//I created a class called ExcelFunctions which has the 
//methods OpenExcelFile and AccessSpecificExcelSheet
var excelFunction = new ExcelFunctions();    

//Open the Excel file
excelWorkbook = excelFunction.OpenExcelFile(excelApp, excelFilePath);

//Get the sheets
Sheets excelSheets = excelWorkbook.Worksheets;

//Access the first sheet
string sheetName = "Sheet1";
Worksheet activeWorksheet = excelFunction.AccessSpecificExcelSheet(excelSheets, sheetName);
                activeWorksheet.Cells[2, 1] = "Write to sheet1";

//Access the second sheet
string sheetName2 = "Sheet2";
activeWorksheet = excelFunction.AccessSpecificExcelSheet(excelSheets, sheetName2);
activeWorksheet.Cells[4, 1] = "Write to sheet2";

这就是我的“AccessSpecificationExcelSheet”方法的样子：

public Worksheet AccessSpecificExcelSheet(Sheets allExcelSheets, string sheetName)
{
    Worksheet selectedWorksheet = allExcelSheets.get_Item(sheetName);
    selectedWorksheet.Select();

    //Select cell A1 when opening
    Range topExcel = selectedWorksheet.get_Range("A1", Type.Missing);
    topExcel.Select();

    return selectedWorksheet;
}

这就是我的“OpenExcelFile”方法的样子：

public Workbook OpenExcelFile(Application excelApp, string excelFilePath)
{
    Workbook excelWorkbook = excelApp.Workbooks.Open(excelFilePath);
    return excelWorkbook;
}
