在c＃中創建和使用excel文件 - Unity

我嘗試從Unity3D應用程序將一些數據寫入excel文件。我創建了以下功能：在c＃中創建和使用excel文件 - Unity

void WriteToExcel(int i, decimal time, decimal speed, int hr) { 

    string file = "newdoc.xls"; 
    Workbook workbook = new Workbook(); 
    Worksheet worksheet = new Worksheet("First Sheet"); 

    worksheet.Cells[i, 0] = new Cell(i); 
    worksheet.Cells[i, 1] = new Cell(time); 
    worksheet.Cells[i, 2] = new Cell(speed); 
    worksheet.Cells[i, 3] = new Cell(hr); 

    worksheet.Cells.ColumnWidth[0, 1] = 3000; 
    workbook.Worksheets.Add(worksheet); 
    workbook.Save(file); 

}

當我嘗試運行應用程序，我得到以下錯誤：

Unhandled Exception: System.TypeLoadException: Could not load type
'ExcelLibrary.SpreadSheet.CellStyle' from assembly 'ExcelLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

誰能告訴我，爲什麼我得到這個例外？因爲我認爲我的程序寫得很好。謝謝。

您可能會考慮使用Microsoft Office Interop庫以外的庫。 EPPlus，NPOI或Open Office XML SDK將是不錯的選擇。 – mason

我相信你會得到這個異常，因爲你使用的DLL文件與Mono不兼容。您需要找到要使用的Mono兼容庫，不是Office Interop庫，不確定關於EPPlus，但是Open Office XML SDK可能是。 –

我通常使用Spreadsheet XML。更換#ColCount因此，#RowCount（被填充的行數，+ 5左右，否則你會得到一個錯誤大方），#Headers並使用一個for循環相應的行#Rows：即

頁眉

<Row> 
<Cell><Data ss:Type="String">s</Data></Cell> 
<Cell><Data ss:Type="String">d</Data></Cell> 
<Cell><Data ss:Type="String">f</Data></Cell> 
<Cell><Data ss:Type="String">h</Data></Cell> 
<Cell><Data ss:Type="String">j</Data></Cell> 
<Cell><Data ss:Type="String">j</Data></Cell> 
</Row>

RowData

<Row> 
<Cell><Data ss:Type="Number">5</Data></Cell> 
<Cell><Data ss:Type="Number">4</Data></Cell> 
<Cell><Data ss:Type="Number">3</Data></Cell> 
<Cell><Data ss:Type="Number">2</Data></Cell> 
<Cell><Data ss:Type="Number">1</Data></Cell> 
<Cell><Data ss:Type="Number">0</Data></Cell> 
</Row>

然後保存作爲filename.xls。讓用處理格式。無需額外的庫或安裝Excel。

快樂編碼。 :)
