问如何在MS visual C++中使用excel

EN

Excel files without using COM interop or OLEDB connection.

Example code: 

//create new xls file
string file = "C:\\newdoc.xls";
Workbook workbook = new Workbook();
Worksheet worksheet = new Worksheet("First Sheet");
worksheet.Cells[0, 1] = new Cell((short)1);
worksheet.Cells[2, 0] = new Cell(9999999);
worksheet.Cells[3, 3] = new Cell((decimal)3.45);
worksheet.Cells[2, 2] = new Cell("Text string");
worksheet.Cells[2, 4] = new Cell("Second string");
worksheet.Cells[4, 0] = new Cell(32764.5, "#,##0.00");
worksheet.Cells[5, 1] = new Cell(DateTime.Now, @"YYYY\-MM\-DD");
worksheet.Cells.ColumnWidth[0, 1] = 3000;
workbook.Worksheets.Add(worksheet);
workbook.Save(file);

// open xls file
Workbook book = Workbook.Load(file);
Worksheet sheet = book.Worksheets[0];

// traverse cells
foreach (Pair<Pair<int, int>, Cell> cell in sheet.Cells)
{
 dgvCells[cell.Left.Right, cell.Left.Left].Value = cell.Right.Value;
}

// traverse rows by Index
for (int rowIndex = sheet.Cells.FirstRowIndex; 
rowIndex <= sheet.Cells.LastRowIndex; rowIndex++)
{
 Row row = sheet.Cells.GetRow(rowIndex);
 for (int colIndex = row.FirstColIndex; 
 colIndex <= row.LastColIndex; colIndex++)
 {
 Cell cell = row.GetCell(colIndex);
 }
 }
