将Excel文件从ASP.NET应用程序上传到MySQL时出错

我正在使用 MySQL 数据库的Web应用程序(ASP.NET).当我尝试通过此应用程序上传Excel文件(.xlsx)时,我没有任何问题.当文件超过24904条记录时,该问题开始.

那时我得到以下错误：

This table contains cells that are outside the range of cells defined in this spreadsheet.

并写入了第24904条记录.

我试图分批加载多个批次,它没有工作.

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

我不会使用OLDB或excel,因为它在阅读excel时创建了许多问题

我使用ExcelDataReader https://github.com/ExcelDataReader/ExcelDataReader

尝试这个

Install-Package 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;
    }
