我正在使用MySQL数据库开发一个Web应用程序(ASP.NET)。当我尝试通过此应用程序上载Excel文件(.xlsx)时,我没有问题。当文件超过24904条记录时,问题就开始了。
此时,我得到以下错误:
此表包含超出此电子表格中定义的单元格范围的单元格。
它记录了前24904条记录。
我试着将负载分成多个批次,但没有成功。
有什么想法吗?
Dim connExcel As New System.Data.OleDb.OleDbConnection(conStr)
Dim cmdExcel As New System.Data.OleDb.OleDbCommand()
Dim dt As New DataTable()
Dim dataset As New DataSet
Dim x As Integer = 2
Dim y As Integer = 20001
Dim range As String = "A" + x.ToString + ":" + "I" + y.ToString
cmdExcel.Connection = connExcel
If erro = 0 Then
Try
For i As Integer = 0 To 50
connExcel.Open()
dataset.Reset()
dataset.Clear()
Dim oda As New System.Data.OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$" & range.ToString & "]", connExcel)
oda.TableMappings.Add("Table", "ExcelTest")
oda.Fill(dataset)
connExcel.Close()
If dataset.Tables(0).Rows.Count > 0 Then
SendToDB(dataset)
Else
i = 50
End If
x = x + 20000
y = y + 20000
range = "A" + x.ToString + ":" + "I" + y.ToString
Next
Label7.Visible = True
Label7.Text = "The information has been written successfully from 0 to " + y.ToString
Catch ex As Exception
Label9.Visible = True
Label9.Text = "Database Error 2:" + ex.Message
connExcel.Close()
End Try
End If
最佳答案
我不使用oldb或excel,因为它在阅读excel时会产生很多问题。
我使用ExcelDataReaderhttps://github.com/ExcelDataReader/ExcelDataReader
试试这个
安装包ExcelDataReader
public static DataSet GetExcelDataSet(string filePath)
{
FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader;
if (Path.GetExtension(filePath) == ".xls")
{
//Choose one of either 1 or 2
//1. Reading from a binary Excel file ('97-2003 format; *.xls)
excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
}
else
{
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
}
//Choose one of either 3, 4, or 5
//3. DataSet - The result of each spreadsheet will be created in the result.Tables
////////DataSet result = excelReader.AsDataSet();
//4. DataSet - Create column names from first row
excelReader.IsFirstRowAsColumnNames = true;
DataSet result = excelReader.AsDataSet();
//5. Data Reader methods
//while (excelReader.Read())
//{
// //excelReader.GetInt32(0);
//}
//6. Free resources (IExcelDataReader is IDisposable)
excelReader.Close();
return result;
}
