大家好,是否可以在不使用的情况下加载excel数据OLEDB
,我已经使用连接字符串编写了一个代码,如下所示.xls and .xlsx
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
在我的系统中,12.0
相关dll
的不存在我得到了一个错误。所以我想知道是否有任何方法可以实现我的要求而不是一般方法
编写的示例代码
public void Method(string pFilePath)
{
DataTable dt = new DataTable();
using (SpreadsheetDocument spreadSheetDocument = SpreadsheetDocument.Open(pFilePath, false))
{
WorkbookPart workbookPart = spreadSheetDocument.WorkbookPart;
IEnumerable<Sheet> sheets = spreadSheetDocument.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>();
string relationshipId = sheets.First().Id.Value;
WorksheetPart worksheetPart = (WorksheetPart)spreadSheetDocument.WorkbookPart.GetPartById(relationshipId);
Worksheet workSheet = worksheetPart.Worksheet;
SheetData sheetData = workSheet.GetFirstChild<SheetData>();
IEnumerable<Row> rows = sheetData.Descendants<Row>();
foreach (Cell cell in rows.ElementAt(0))
{
dt.Columns.Add(GetCellValue(spreadSheetDocument, cell));
}
foreach (Row row in rows)
{
DataRow tempRow = dt.NewRow();
for (int i = 0; i < row.Descendants<Cell>().Count(); i++)
{
tempRow[i] = GetCellValue(spreadSheetDocument, row.Descendants<Cell>().ElementAt(i - 1));
}
dt.Rows.Add(tempRow);
}
}
dt.Rows.RemoveAt(0);
}
public static string GetCellValue(SpreadsheetDocument document, Cell cell)
{
SharedStringTablePart stringTablePart = document.WorkbookPart.SharedStringTablePart;
string value = cell.CellValue.InnerXml;
if (cell.DataType != null && cell.DataType.Value == CellValues.SharedString)
{
return stringTablePart.SharedStringTable.ChildElements[Int32.Parse(value)].InnerText;
}
else
{
return value;
}
}
但是在foreach (Row row in rows)
这种情况下,我遇到了一个例外Specified argument was out of the range of valid values.
Parameter name: index
