Hi,i try to search this code.. i'm not really sure its work this,but you try it.. thank you?

you could try with this Excel C# / VB.NET library. They send .NET 1.1 library on demand.

Here is a sample Excel C# code how to export DataSet to Excel:

var ef = new ExcelFile();

foreach (DataTable dataTable in dataSet.Tables)
ef.Worksheets.Add(dataTable.TableName).InsertDataTable(dataTable, 0, 0, true);

ef.SaveXlsx(dataSet.DataSetName + ".xlsx");

Hi Promit,

Please use these codes to export your data table to excel.

If dgInvoice_SalesReport_Accounts.RowCount = Nothing Then
            MessageBox.Show("Sorry nothing to export into excel sheet.." & vbCrLf & "Please retrieve data in datagridview", "", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Exit Sub
        End If
        Dim rowsTotal, colsTotal As Short
        Dim I, j, iC As Short
        System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor
        Dim xlApp As New Excel.Application

        Try
            Dim excelBook As Excel.Workbook = xlApp.Workbooks.Add
            Dim excelWorksheet As Excel.Worksheet = CType(excelBook.Worksheets(1), Excel.Worksheet)
            xlApp.Visible = True

            rowsTotal = dgInvoice_SalesReport_Accounts.RowCount
            colsTotal = dgInvoice_SalesReport_Accounts.Columns.Count - 1
            With excelWorksheet
                .Cells.Select()
                .Cells.Delete()
                For iC = 0 To colsTotal
                    .Cells(1, iC + 1).Value = dgInvoice_SalesReport_Accounts.Columns(iC).HeaderText
                Next
                For I = 0 To rowsTotal - 1
                    For j = 0 To colsTotal
                        .Cells(I + 2, j + 1).value = dgInvoice_SalesReport_Accounts.Rows(I).Cells(j).Value
                    Next j
                Next I
                .Rows("1:1").Font.FontStyle = "Bold"
                .Rows("1:1").Font.Size = 14


                .Cells.Columns.AutoFit()
                .Cells.Select()
                .Cells.EntireColumn.AutoFit()
                .Cells(1, 1).Select()
            End With
        Catch ex As Exception
            MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        Finally
            'RELEASE ALLOACTED RESOURCES
            System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.Default
            xlApp = Nothing
        End Try
