大家好,是否可以在不使用OLEDB
的情况下加载Excel数据,我已经使用连接字符串为.xls和.xlsx
编写了代码,如下所示
ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ pFilePath + ";扩展属性=\"Excel 8.0;HDR=Yes;IMEX=2\"";
ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+ pFilePath + ";扩展属性=\"Excel 12.0;HDR=Yes;IMEX=2\"";
在我的系统中,与 12.0
相关的 dll
不存在,我收到错误。所以我想知道是否有什么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,我收到一个异常,因为 指定的参数超出了有效值的范围。
参数名称:索引
最佳答案
我从 excel 读入 mysql 数据库。也许不是最好的方法。 但这是我的代码:
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"\\xxxx\yyyy.xlsx");
Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
Excel.Range xlRange = xlWorksheet.UsedRange;
int rowCount = xlRange.Rows.Count;
int colCount = xlRange.Columns.Count;
string Kund = "";
for (int i = 1; i <= rowCount; i++)
{
for (int j = 1; j <= colCount; j++)
{
if ((j == 1) && (i > 1))
{
MySqlConnection conn = new MySqlConnection(databas);
Kund = xlRange.Cells[i, j].Value2.ToString();
}
...
}
...
}
xlApp.Workbooks.Close();
您必须使用using Excel = Microsoft.Office.Interop.Excel;
